15 Best Waterproof Motorcycle Side Cases Sets for 2027

A waterproof motorcycle side cases set can keep touring gear sheltered, but the right choice depends on whether you prioritize hard-shell protection, soft-bag flexibility, or easy bike fitment. My best overall pick is the Tusk Aluminum Panniers V2, Large, which stands out as a substantial hard-case option; the KEMIMOTO 50L saddlebags offer a softer, lighter approach, while the SHAD SH23 suits riders who want a smaller hard-case pair. Capacity, mounting compatibility, weight, and how water resistance is achieved are the main tradeoffs. Read on for the full breakdown of all 15 options and guidance on matching a set to your motorcycle.

Key Takeaways

• Hard cases dominate the larger-capacity choices: Several aluminum pairs are listed at 36–38L, while the Tusk Large panniers are the lineup’s adventure-oriented hard-case contenders.
• The KEMIMOTO set makes capacity its main distinction: Its 50L total soft-bag capacity is higher than the 28L HI-LINE set, but soft bags do not provide the same rigid impact protection as aluminum cases.
• Mounting hardware can change the real value: GSTP’s 36L set and several 18L or 38L aluminum sets specify support racks, while many universal cases may need separate compatible racks.
• Small cases suit different jobs: The 18L aluminum pairs and 23L SHAD SH23 trade packing space for a more compact setup; the RIDEIRON 5L-per-side bags are auxiliary storage, not substitutes for full panniers.
• Waterproof claims need a fit-and-seal check: The product names identify waterproof or aluminum construction, but buyers should confirm closure design, lid seals, and mounting fit before relying on any set for sustained rain.

More Details on Our Top Picks

1. HI-LINE Waterproof Motorcycle Saddlebags, 28L

   

   Best for Flexible, Tool-Free Mounting

   View on Amazon

   The HI-LINE set suits riders who want soft, waterproof storage without committing to hard cases or a rack system. Its two 14L compartments provide 28L total, less room than the KEMIMOTO 50L saddlebags, but the smaller footprint may be easier to manage on bikes where bulky luggage is a concern. Roll-top PVC closures help keep rain out, while padded interiors add a buffer for packed gear. Adjustable throw-over straps allow tool-free mounting, and the detachable shoulder strap makes a bag easier to carry off the bike. The tradeoff is that universal fit still calls for checking strap placement and exhaust clearance on your motorcycle. This is a practical pick for moderate loads, not riders who need the capacity or rigid security of aluminum cases.

   Pros:

   • Waterproof PVC construction with roll-top closures
   • Tool-free throw-over mounting with adjustable straps
   • Padded interiors help cushion stored gear
   • Detachable shoulder strap and reflective accents add carrying convenience and visibility

   Cons:

   • Universal fit requires checking placement on the specific motorcycle
   • 28L total capacity may be restrictive for longer trips
   • Soft bags do not provide the rigid structure or locking security of aluminum cases

   Best for: Riders who want waterproof, removable luggage for weekend trips and prefer not to install hard-case racks.

   Not ideal for: Touring riders carrying bulky loads or anyone who needs lockable hard cases; the 28L capacity is split between two soft compartments.

   • Total capacity:28L (2 x 14L)
   • Material:Polyvinyl chloride (PVC)
   • Closure:Roll closure
   • Mounting:Throw-over seat mount with adjustable straps
   • Water resistance:Waterproof
   • Dimensions:18.1 x 6.7 x 13.8 in
   • Weight:6.6 lb
   • Compartments:2
   Our verdict

   “Choose the HI-LINE set for removable, rain-ready luggage and simple mounting when 28L is enough.”

2. KEMIMOTO Waterproof Motorcycle Saddlebags, 50L (25L × 2)

   

   Best for Maximum Soft-Bag Capacity

   View on Amazon

   With 50L across two 25L bags, this KEMIMOTO set is the capacity leader among the soft options here. It gives touring and adventure riders more room than the HI-LINE’s 28L set, while keeping the detachable, seat-mounted format rather than requiring hard-case hardware. Heavy-duty, tear-resistant PVC and waterproof construction suit gear exposed to road spray, and adjustable spacing helps the pair fit different seat widths. That flexibility has limits: the listing calls for at least 3 inches of exhaust clearance and names the DRZ400S and NC750 as incompatible. The bags also lack the rigid shell and built-in security locks of the 38L aluminum cases. I’d choose these when carrying volume matters more than hard-case protection, provided the bike’s exhaust and fit are suitable.

   Pros:

   • 50L total capacity with 25L per bag
   • Waterproof, tear-resistant heavy-duty PVC
   • Detachable bags and adjustable 12–16.5-inch spacing
   • Reflective details improve visibility

   Cons:

   • Requires at least 3 inches of exhaust clearance
   • Listed as incompatible with DRZ400S and NC750
   • Soft construction does not offer the rigid impact protection or locking security of aluminum cases

   Best for: Touring and adventure riders who need substantial soft-bag capacity and can confirm safe exhaust clearance on their motorcycle.

   Not ideal for: DRZ400S or NC750 owners, riders unable to keep 3 inches from the tailpipe, and buyers seeking lockable rigid cases.

   • Capacity:50L (25L per bag)
   • Load capacity:Up to 50 kg
   • Material:Heavy-duty PVC
   • Water resistance:Waterproof
   • Dimensions:15.8 x 9 x 11.8 in
   • Weight:2.52 kg
   • Mounting:Seat mount
   • Adjustable bag spacing:12–16.5 in
   • Exhaust clearance:At least 3 in
   Our verdict

   “Pick the KEMIMOTO set when you need more soft-bag room than the HI-LINE offers and your bike meets its fit and exhaust-clearance requirements.”

3. Motorcycle Side Box Durable Luggage Side Bags with Security Lock, Aluminum Waterproof Motorcycle Two Sides Boxes Storage Case for Travel, Black

   

   Best for Lockable Hard-Case Protection

   View on Amazon

   These cases are aimed at riders who value a rigid, lockable shell over the easy removal and light carrying of soft saddlebags. The pair offers 38L total capacity in 1.5mm aluminum alloy, with reinforced stress points and stated waterproof and dustproof protection. Compared with the 50L KEMIMOTO set, storage is lower, but the hard construction and security locks make these a better match for riders who want a more substantial barrier around their luggage. The cost of that structure is weight: 8.9kg for the pair can affect handling, and the package does not include side racks or other mounting hardware. The universal-fit claim is not a substitute for checking rack dimensions and bike compatibility. I’d shortlist these for travel only if the mounting setup is already sorted.

   Pros:

   • 1.5mm aluminum alloy construction with reinforced stress points
   • Stated waterproof and dustproof protection
   • Security locks help secure stored items
   • 38L capacity in a pair of hard cases

   Cons:

   • Side racks and mounting hardware are not included
   • The 8.9kg pair adds substantial weight
   • Dimensions and mounting compatibility need checking for the specific motorcycle

   Best for: Touring riders who want lockable aluminum luggage and already have, or plan to source, compatible side racks.

   Not ideal for: Riders seeking a light, quick-to-remove soft set or a complete ready-to-mount package; racks are not included and the pair weighs 8.9kg.

   • Material:Aluminum alloy
   • Material thickness:1.5mm
   • Capacity:38L
   • Dimensions:45 x 23 x 37cm (17.7 x 9 x 14.5 in)
   • Weight:8.9kg for the pair
   • Color:Black
   • Water and dust protection:Waterproof and dustproof
   • Security:Security locks
   Our verdict

   “Choose these cases for lockable, weather-protective hard luggage if you can provide compatible racks and accept the added weight.”

   → See it on Amazon →

4. 38L Waterproof Aluminum Motorcycle Side Cases, Pair

   

   Best for Padded, Locking Hard Cases

   View on Amazon

   This 38L pair makes sense for riders who want hard aluminum cases with a padded interior for separating luggage from the case walls. Like the B0CZ46VZ1K aluminum set, it offers waterproof and dustproof construction and the same stated total capacity, but its supplied PU inner pads and double-lock closure give it a more clearly specified interior and locking setup. Those details come with a major fitment caveat: mounting brackets are not included, so the listed rack- or seat-mount options do not mean it arrives ready for every motorcycle. At 10,430g, it is also heavier than the other 38L aluminum pair in this roundup. I’d favor this set when interior padding and double locks matter more than minimizing luggage weight, and only after confirming the bracket arrangement.

   Pros:

   • 38L total storage in two aluminum cases
   • Waterproof and dustproof design
   • PU inner pads and reinforced corners help protect packed items
   • Double-lock closure includes keys

   Cons:

   • Mounting brackets are not included
   • At 10,430g, the pair is heavier than the other listed 38L aluminum set
   • Compatibility must be checked before purchase

   Best for: Riders seeking two lockable, padded aluminum cases who have compatible mounting brackets or can source them separately.

   Not ideal for: Buyers who need a complete mounting kit or want to keep added luggage weight low; brackets are absent and the pair weighs 10,430g.

   • Material:Aluminum alloy
   • Capacity:38L
   • Dimensions:17.76 x 14.43 x 8.94 in
   • Weight:10,430g
   • Mounting type:Rack mount, seat mount
   • Closure:Double lock
   • Water resistance:Waterproof
   • Compartments:2
   • Package contents:Two side cases, PU inner pads, keys, reflective stickers, side case hooks; mounting brackets not included
   Our verdict

   “Choose this pair over the B0CZ46VZ1K when padded interiors and double locks are priorities and the missing brackets are not a problem.”

   → See it on Amazon →

5. Universal Motorcycle Side Panniers – 18L Aluminum Alloy Hard Saddlebag for Motorbikes (Black)

   

   Best Compact Hard-Case Set

   View on Amazon

   The standout here is its compact 18L capacity: this aluminum pannier set is a better fit for riders who want a smaller hard-case setup than the 38L B0DK5283L9 pair, not a substitute for high-volume touring luggage. The product data lists waterproof, dustproof and shockproof protection, along with safety locks and a removable insulation lining. A metal handle also supports carrying the case away from the motorcycle. Those practical details come with unanswered fitment questions: no mounting dimensions or hardware compatibility are specified, so the universal label alone does not confirm a secure fit on a given bike. The metal construction may also add weight, though no weight is provided. Compared with the HI-LINE soft bags, this is the more rigid and lockable direction, but it offers less capacity and less flexible installation information.

   Pros:

   • Aluminum alloy hard-case construction
   • Listed as waterproof, dustproof, and shockproof
   • Safety locks and double keys provide a locking option
   • Removable lining and metal carrying handle add utility off the bike

   Cons:

   • 18L capacity may not fit luggage for longer trips
   • Mounting hardware compatibility is not specified
   • Metal construction may add weight, but no product weight is provided

   Best for: Commuters and short-trip riders who want compact, lockable hard luggage for essentials rather than full touring loads.

   Not ideal for: Long-distance travelers carrying bulky gear, or riders who need confirmed mounting compatibility and included hardware before buying.

   • Material:Aluminum alloy
   • Capacity:18L
   • Color:Black
   • Water protection:Waterproof
   • Other protection:Shockproof, dustproof, wear-resistant
   • Security:Safety locks with double keys
   • Interior:Removable insulation lining
   • Carrying feature:Metal handle
   Our verdict

   “Choose these panniers for compact, lockable hard storage when 18L is sufficient and you can confirm the mounting fit independently.”

   → See it on Amazon →

6. CORGLI Motorcycle Aluminum Side Cases with Security Locks, Silver, 38 L Pair

   

   Best for a Lightweight Aluminum Pair

   View on Amazon

   The CORGLI 38 L pair suits riders who want hard aluminum cases without the heavier listed weight of the GSTP 36 L set. Its pair weighs 8.9 kg, and the 1.5 mm reinforced alloy shell, locking closures, and stated waterproof and dustproof protection make it a stronger match for wet-weather touring than options without an explicit waterproof claim, such as the TUSK Aluminum Panniers V2. That claim is useful, but no specific sealing method is described, so I would not treat it as proof of submersion protection. The cases include mounting hardware, but side racks are not included; universal fit also means checking rack compatibility and exhaust clearance before buying. With 38 liters total, it offers less capacity than the two 37-liter TUSK boxes combined, but a more manageable load for riders who do not need that volume.

   Pros:

   • Stated waterproof and dustproof construction suits exposed touring gear.
   • Reinforced 1.5 mm aluminum alloy shell.
   • 38 liters of combined storage with locking closures and two keys.
   • Listed pair weight of 8.9 kg is lower than the GSTP 36 L set’s 17.28 kg.

   Cons:

   • Side racks are not included, despite mounting hardware being supplied.
   • Universal fit requires checking motorcycle, rack, and exhaust clearance.
   • No specific gasket or sealing design is described to support the waterproof claim.

   Best for: Touring riders who want lockable, hard-sided storage with stated waterproof protection and a listed pair weight below 9 kg.

   Not ideal for: Riders without compatible side racks or those who need a confirmed rack-included kit; the cases also call for careful exhaust-clearance and fit checks.

   • Material:1.5 mm aluminum alloy
   • Capacity:38 liters total
   • Dimensions:45 × 23 × 37 cm (17.7 × 9 × 14.5 in) each
   • Pair weight:8.9 kg (19.6 lb)
   • Water resistance:Described as waterproof and dustproof
   • Lock:Security lock with two keys
   • Compatibility:Universal fit; mounting hardware included; side racks not included
   • Color:Silver
   Our verdict

   “Choose the CORGLI pair for relatively light, lockable aluminum storage with a stated waterproof rating, provided you already have compatible racks.”

   → See it on Amazon →

7. Tusk Aluminum Panniers V2, Large, Silver

   

   Best for Flexible Lid Access

   View on Amazon

   The TUSK Aluminum Panniers V2 stand out for their lid design: the two-way latch lets a rider open either side or remove the lid, which can make packing and reaching gear easier at camp. Each box holds 37 liters, giving this pair far more stated capacity than the 23-liter SHAD SH23. Reinforced welds, seamless rear edges, a powder-coated finish, and a rubber gasket add practical durability and help limit water entry. Still, the listed rating is only water resistant, not waterproof, so I would rank the CORGLI pair ahead for buyers prioritizing an explicit waterproof claim. The TUSK set also needs rack-mount hardware that is not included. Its matched locks and bolt-on loops are useful for securing the cases and strapping extra gear, but the large capacity may be more box than lighter-packing riders need.

   Pros:

   • 37 liters per pannier offers substantial carrying capacity.
   • Two-way latch allows access from either side or complete lid removal.
   • Rubber gasket helps keep contents dry, with reinforced welds and seamless rear edges.
   • Includes four matched locks and bolt-on loops for extra gear.

   Cons:

   • Listed as water resistant rather than waterproof.
   • Mounting hardware is not included.
   • Large cases can be excessive for riders carrying only daily essentials.

   Best for: Adventure and touring riders who want large aluminum panniers with adaptable lid access, matched locks, and tie-down loops.

   Not ideal for: Riders who need a clearly stated waterproof rating or expect mounting hardware and compatible racks to come in the box.

   • Material:Aluminum
   • Capacity:37 liters per box
   • Dimensions:18 × 9.25 × 15.5 inches per box
   • Quantity:2 panniers
   • Water resistance:Water resistant; rubber gasket
   • Mounting:Rack mount; mounting hardware not included
   • Included security:4 matched locks and keys
   • Finish and color:Powder-coated silver
   Our verdict

   “Pick the TUSK pair if capacity and flexible lid access matter more than a stated waterproof rating or included mounting hardware.”

   → See it on Amazon →

8. SHAD D0B23100 Side Cases SH23, Black, 23L

   

   Best Compact Option for Everyday Loads

   View on Amazon

   The SHAD SH23 is the compact choice in this group, with 23 liters of capacity for commuting gear or a lighter weekend load. Its polycarbonate construction and rack-mount strap offer a different approach from the aluminum CORGLI and TUSK cases: less emphasis on metal-box touring capacity, more on a smaller, sporty case with carry and mounting handles. The zippered closure is easy to use, but the product data gives no waterproof rating, making this a weaker fit for riders who need dependable protection through sustained rain. The GSTP cases also fall short of a waterproof rating, yet they include a hard aluminum shell, locks, lining, and support rack; the SHAD listing specifies a vehicle-specific fit and gives no comparable rack-included claim. I would choose it for modest loads and skip it for exposed, wet-weather travel.

   Pros:

   • 23-liter capacity fits a compact everyday load.
   • Polycarbonate material avoids an aluminum-box design.
   • Carry and mounting handles support transport and installation.
   • Two-year warranty is listed.

   Cons:

   • No explicit waterproof rating is provided, and the closure is zippered.
   • Single compartment limits separation of gear.
   • Vehicle-specific fit may restrict compatibility compared with universal-fit aluminum sets.

   Best for: Commuters and sport-oriented riders seeking a compact rack-mounted case for everyday essentials and lighter trips.

   Not ideal for: Riders carrying bulky touring gear or requiring an explicitly waterproof case for regular wet-weather riding.

   • Material:Polycarbonate (PC)
   • Capacity:23 liters
   • Dimensions:19 × 14 × 11 inches
   • Weight:9 lb
   • Closure:Zipper
   • Mounting:Rack mount with adjustable strap
   • Fit:Vehicle specific
   • Compartments:1
   • Warranty:2 years
   Our verdict

   “Choose the SHAD SH23 for compact everyday storage, not as a first choice for riders whose main requirement is waterproof touring protection.”

   → See it on Amazon →

9. GSTP Universal Motorcycle Side Cases with Support Racks, 36 L, Black Aluminum

   

   Best Rack-Included Touring Kit

   View on Amazon

   The GSTP set is the most ready-to-mount option here because it includes a support rack, while the CORGLI cases require separate side racks and the TUSK panniers omit mounting hardware. That bundled hardware can simplify a purchase, though the stated universal fit still calls for checking the motorcycle and installation details. The two aluminum cases provide 36 liters total, with locks, carrying handles, reflective strips, and removable washable lining—useful touches for riders who carry dusty or damp gear. Its water rating is only water resistant, not waterproof, so the CORGLI pair is a better match for buyers who prioritize an explicit waterproof claim. Weight is the larger tradeoff: the listed 17.28 kg is substantial before cargo is added. I would favor GSTP for buyers who value a bundled rack and lined cases over low overall weight.

   Pros:

   • Support rack and lock accessories are included.
   • Hard aluminum cases provide 36 liters of combined storage.
   • Removable washable lining helps with cleanup after carrying dirty or damp gear.
   • Reflective strip and carrying handles add practical utility.

   Cons:

   • Listed item weight of 17.28 kg is heavy before luggage is added.
   • Water resistance is listed as water resistant, not waterproof.
   • Universal fit still requires checking compatibility with the motorcycle.

   Best for: Touring riders who need aluminum cases with support racks and washable liners included in the same kit.

   Not ideal for: Weight-conscious riders or anyone who needs a stated waterproof rating for frequent heavy-rain travel.

   • Material:Aluminum
   • Capacity:36 liters total
   • Quantity:2 cases
   • Fit:Universal motorcycle fit
   • Mounting:Rack mount; support rack included
   • Water resistance:Water resistant
   • Item weight:17.28 kg
   • Included accessories:Two keys, replacement lock cylinder, reflective strip
   Our verdict

   “Choose the GSTP kit if included support racks and washable liners outweigh its substantial listed weight and water-resistant-only rating.”

   → See it on Amazon →

10. Universal 18L Aluminum Motorcycle Side Cases with Support Racks, Silver and Black

    

    Best for Smaller, Organized Loads

    View on Amazon

    These 18 L aluminum cases suit riders who prefer two smaller boxes over the larger combined loads offered by the CORGLI 38 L pair or the GSTP 36 L kit. Each case has removable, washable PU thermal lining, which helps separate and clean up gear, while the included support rack kit avoids the separate-rack hurdle found with the CORGLI and TUSK sets. The cases are described as waterproof, dustproof, and shock-resistant, a more direct weather-protection claim than the GSTP’s water-resistant rating. That said, the listing gives no sealing details, and fit may vary by motorcycle, so I would verify the rack setup before purchase. At a listed 21.3 lb, this pair is not especially light; its appeal is the smaller per-case capacity and bundled accessories, not a low total load.

    Pros:

    • 18 liters per case keeps each side’s storage more limited than the 36–38-liter sets.
    • Described as waterproof, dustproof, and shock-resistant.
    • Support rack kit, keys, and reflective strips are included.
    • Removable washable PU thermal lining supports easier cleaning and gear separation.

    Cons:

    • Listed pair weight is 21.3 lb despite the smaller per-case capacity.
    • Motorcycle fit may vary, and dimensions are stated as manually measured.
    • No specific waterproof sealing design is provided.

    Best for: Riders who want two modest-capacity aluminum cases, included support racks, and removable liners for commuting or short trips.

    Not ideal for: Long-distance tourers carrying bulky equipment, or buyers who need a verified fit for a specific motorcycle without checking measurements.

    • Material:Aluminum alloy
    • Capacity:18 liters per case
    • Dimensions:19.7 × 36 × 32 cm (7.75 × 14.17 × 12.16 in)
    • Weight:21.3 lb
    • Water resistance:Described as waterproof and dustproof
    • Features:Shock-resistant, lockable, quick release
    • Lining:Removable, washable PU thermal lining
    • Included:Two side cases, support rack kit, keys, reflective strips
    Our verdict

    “Pick these cases for smaller, lined aluminum storage with a rack kit included, but check fit and accept the relatively heavy listed pair weight.”

    → See it on Amazon →

11. GXYWADY Universal 36L Aluminum Motorcycle Side Cases, Black

    

    Best Straightforward Hard-Case Set

    View on Amazon

    The GXYWADY 36L pair makes sense for riders who want aluminum protection without moving to one of the larger, heavier sets. Its 36-liter capacity and included support racks give buyers a more complete starting package than the Tusk Aluminum Panniers V2, which do not include mounting hardware. The product information does not specify a waterproof seal, though, so I would not treat its hard shell as proof that it will keep contents dry in sustained rain. A single compartment keeps the layout simple but offers less organization than the 38L Aluminum Motorcycle Side Case Set with its removable PU lining. Check rack compatibility before buying: “universal” does not guarantee that the supplied racks fit every motorcycle. This is a practical pick for basic lockable storage, not the strongest documented choice for all-weather waterproofing.

    Pros:

    • 36-liter capacity in a hard-shell aluminum pair
    • Support racks and keys are included
    • Replacement lock cylinder provides a spare option
    • Reflective stickers add visibility

    Cons:

    • No waterproof seal is specified in the product data
    • Rack compatibility needs checking for the individual motorcycle
    • Single-compartment design limits organization

    Best for: Riders seeking a moderate-capacity aluminum pair with support racks and included locks for a motorcycle whose rack fit they can verify.

    Not ideal for: Riders who need documented waterproof sealing, built-in organization, or a confirmed rack fit without checking their motorcycle.

    • Material:Aluminum
    • Shell type:Hard
    • Capacity:36 liters
    • Fit:Universal
    • Mounting:Rack mount
    • Compartments:1
    • Color:Black
    • Included items:Pair of side cases, keys, replacement lock cylinder, support racks, reflective stickers
    Our verdict

    “Choose this set for included rack hardware and straightforward aluminum storage, but pick a case with a stated seal if keeping luggage dry is the priority.”

    → See it on Amazon →

12. 38L Aluminum Motorcycle Side Case Set with Support Racks

    

    Best Documented Weather Protection

    View on Amazon

    Among these hard cases, this set makes the clearest case for wet-weather luggage protection: its waterproof and dustproof seal is stated directly, and the removable PU lining adds a layer between gear and the metal shell. At 38 liters per case, it also offers more stated capacity than the GXYWADY 36L pair, while the separate left- and right-side dimensions accommodate an asymmetric shape. That extra room comes with a real cost: the listed pair weighs 32.85 pounds, before luggage, so riders sensitive to added load should compare it with soft bags such as the RIDEIRON 5L pair. Tool-free installation is claimed for many motorcycles, but fit still varies, and the listing’s dimensions are worth checking against the bike and rack. I’d rank it highest here when stated sealing matters more than keeping weight down.

    Pros:

    • Waterproof and dustproof seal is specifically stated
    • 38 liters per case with removable PU lining
    • Reinforced corners and stainless steel locks
    • Reflective stickers and handles are included

    Cons:

    • Listed pair weight of 32.85 pounds adds substantial load
    • Fit may vary between motorcycle models
    • Asymmetric dimensions require checking clearance on both sides

    Best for: Touring riders who want a stated waterproof and dustproof seal, lined interiors, and high capacity, and whose motorcycle can accommodate the case dimensions and weight.

13. Tusk Aluminum Panniers V2, Large, Black (Pair)

    

    Best for Riders With Existing Pannier Racks

    View on Amazon

    The Tusk V2 earns its place with a clearly described waterproof lid and rubber gasket, reinforced welded seams, and a black powder-coated finish. Each 37-liter box gives a little less stated volume than the 38L Aluminum Motorcycle Side Case Set, but Tusk supplies four matched locks and keys and is compatible with most pannier racks. The catch is that mounting hardware is not included, so this pair suits riders who already have a suitable rack and can source the required fixings. At 38 pounds for the pair, it is also a substantial load; the RIDEIRON soft bags are far lighter in concept and better for small essentials, though they offer much less capacity and a different level of hard-shell protection. I’d favor Tusk when a gasketed lid and established rack setup matter more than a ready-to-mount package.

    Pros:

    • Waterproof lids use rubber gaskets
    • Reinforced welded seams and powder-coated finish
    • Four matched locks and keys are included
    • Four mounting loops on each box

    Cons:

    • Mounting hardware is not included
    • Pair weighs 38 pounds
    • Rack compatibility still needs confirmation

    Best for: Touring riders with a compatible pannier rack who want large aluminum cases with stated gasketed-lid waterproofing and matched locks.

    Not ideal for: Riders without a rack or mounting hardware, or those trying to minimize the weight added to their motorcycle.

    • Material:Aluminum
    • Capacity:37 liters per box
    • Dimensions:18 × 9.25 × 15.5 inches per box
    • Pair weight:38 pounds
    • Water resistance:Waterproof lids with rubber gaskets
    • Mounting:Rack mount; compatible with most pannier racks
    • Locks:Four matched locks and keys included
    • Mounting hardware:Not included
    Our verdict

    “Choose Tusk if you already have a compatible rack and want gasketed aluminum cases; skip it if you need mounting hardware in the box.”

14. RIDEIRON Motorcycle Side Bags 5L x 2 Waterproof Sissy Bar Crash Bar Bags

    

    Best Compact Waterproof Set

    View on Amazon

    The RIDEIRON pair is the compact choice here: its two 5-liter roll-top bags are aimed at small essentials, not the touring loads that fit in the Tusk V2 or the 38L Aluminum Motorcycle Side Case Set. Its seam-sealed 500D PVC construction and roll-top closure are explicitly described as waterproof, making the weather-protection claim more direct than the GXYWADY listing, which does not specify a seal. Quick-release buckles, four straps, and a shoulder strap make the bags easier to remove and carry off the motorcycle, while customizable patches and reflective strips add practical visibility and personalization. The tradeoff is capacity: 10 liters total will not replace full-size side cases. Attachment also depends on suitable mounting points and careful installation, so I’d check the bike’s bars or luggage setup before choosing them.

    Pros:

    • Waterproof 500D PVC with seamless sealing and roll-top closures
    • Quick-release buckles and four buckle straps
    • Shoulder strap and top handle support off-bike carrying
    • Reflective strips and customizable patches

    Cons:

    • 10 liters total is too little for substantial touring luggage
    • Secure installation requires suitable attachment points and care
    • Fit may not suit every motorcycle

    Best for: Commuters and day riders who need a small amount of explicitly waterproof storage that can be detached and carried by hand.

    Not ideal for: Touring riders carrying bulky clothing or camping gear, or owners whose motorcycle lacks secure attachment points for the straps.

    • Capacity:5 liters per bag; 10 liters total
    • Material:500D PVC
    • Closure and construction:Seamless sealing, roll-top closure
    • Attachment:Quick-release buckles and four buckle straps
    • Carrying options:Shoulder strap and top handle
    • Visibility and customization:Reflective strips and customizable patches
    • Included items:Pair of bags, shoulder strap, top handle, four buckle straps
    Our verdict

    “Choose RIDEIRON for compact, detachable waterproof storage, not as a substitute for full-size panniers.”

15. Greensen ABS Hard Saddlebags with Lock & Key, 22L per Bag, Universal Fit for Cruiser and Touring Motorcycles, Matte Black

    

    Best Lockable ABS Option for Cruisers

    View on Amazon

    Greensen offers a middle ground for cruiser and touring owners who want lockable hard cases without the aluminum construction of the Tusk V2 or the 38L Aluminum Motorcycle Side Case Set. Each 22-liter ABS bag provides useful everyday space, but the pair’s 44 liters total is spread across smaller cases rather than the large individual boxes offered by those aluminum sets. The product is described as weather-resistant, not explicitly waterproof, so I would not choose it over RIDEIRON’s stated roll-top waterproofing or Tusk’s gasketed lids for frequent heavy rain. Its universal-fit claim also does not remove the need to confirm mounting hardware for a specific cruiser or touring bike. The lock and key add a basic security feature, while the listed ABS-and-metal construction keeps this option distinct from all-metal panniers. Fit and dry-weather expectations should guide the decision.

    Pros:

    • 22 liters of capacity per bag
    • Lock-and-key security feature
    • ABS plastic and metal construction
    • Designed for cruiser and touring motorcycles

    Cons:

    • Weather-resistant description does not specify waterproof sealing
    • Mounting hardware may be needed for some motorcycles
    • Capacity per case is smaller than the 37L Tusk V2 boxes

    Best for: Cruiser and touring riders who want lockable ABS hard cases for everyday storage and can verify the required mounting hardware.

    Not ideal for: Riders who need a clearly stated waterproof seal, large single-case capacity, or a confirmed bolt-on fit for their motorcycle.

    • Material:ABS plastic and metal
    • Capacity:22 liters per bag
    • Color:Matte black
    • Fit:Universal fit for cruiser and touring motorcycles
    • Weather protection:Weather-resistant
    • Security:Lock and key
    Our verdict

    “Pick Greensen for lockable, moderate-capacity ABS storage on a compatible cruiser, but choose a gasketed or roll-top option for stronger documented rain protection.”

How We Picked

I ranked these options around the needs implied by a waterproof side-case set: paired storage, protection from weather, useful capacity, mounting practicality, and the likely demands of road or touring use. I gave more weight to products with clearly stated paired capacity and a defined case style, then considered whether the listing names support racks or security locks. Those details affect the complete setup a rider may need, not just the boxes themselves.

The ranking also reflects meaningful differences between soft saddlebags, aluminum panniers, and ABS hard cases. Larger hard cases earn higher placement for riders carrying bulky gear and seeking rigid storage, while compact cases and small auxiliary bags rank lower for general touring because they serve narrower needs. Product names alone do not establish bike compatibility, waterproof performance under every condition, or rack inclusion, so I treat those as points buyers should verify rather than assume.

Factors to Consider When Choosing Motorcycle Side Cases Waterproof Set

Start with the motorcycle and the trips you actually take, not the largest capacity figure in a listing. A side-case set only works well when the rack, exhaust clearance, load limits, and closure style suit your bike and routine.

Match the mounting system to your motorcycle

“Universal” does not mean every case bolts directly to every motorcycle. Many hard panniers attach to a rack system, and rack geometry can vary by model, year, exhaust position, and passenger hardware. Before buying, check whether the package includes racks or only cases, then confirm the maker’s fitment details against your exact bike. A set with support racks listed may reduce parts hunting, but the racks still need to match your motorcycle. Avoid assuming that a generic bracket can safely carry a loaded case without confirming its rating and attachment points.

Choose capacity by load shape, not just liters

Capacity figures help compare sets, but the shape of a case determines whether your gear fits comfortably. A narrow case may hold less bulky clothing yet work better around a passenger’s leg or a high-mounted exhaust. Two cases with similar volume can differ in lid opening, usable depth, and access while the bike is parked. Plan around the items you carry most often, such as a helmet, rain layer, tools, or camping gear, and check dimensions where available. Oversizing can add width and weight you rarely use, while undersizing may force gear onto the seat.

Understand what “waterproof” means for the closure

Water resistance depends on seams, lids, zippers, gaskets, and how the case closes—not only on a product title. Rigid aluminum or ABS shells can shelter gear, but lid seals and latch alignment still matter in heavy rain. Soft bags may rely on roll-top closures, coated fabric, or separate liners, each with different packing and access habits. Look for clear information about closure construction and care, and use dry bags for electronics or other items that cannot get wet. If the listing leaves the sealing method unclear, treat waterproof performance as something to verify before a long wet-weather trip.

Balance protection against weight and width

Hard cases provide a rigid barrier and can make gear easier to organize, but they add weight and can make a motorcycle wider. Soft saddlebags are often easier to compress or remove, though they offer less rigid protection and may need careful mounting away from hot exhausts and moving parts. Check the motorcycle’s payload limit and include the cases, racks, passenger, and luggage in your calculation. Also consider the narrowest places you ride or park; a wide pair can complicate filtering through traffic or fitting into a garage. Pick the lightest construction that still meets your security and protection needs.

Treat locks as access control, not theft-proofing

A listed lock can deter casual access and keep a lid closed, but it does not make a case or its rack immune to theft. Check whether the lock secures the lid, the case to the rack, or both, since those functions are different. Key management matters on multi-case setups, and replacement keys or lock components may be harder to source for less-established systems. For overnight stops, remove valuables or take them inside rather than relying on a case lock alone. Buyers who need frequent quick access may prefer simple, reliable latches over a more complicated locking arrangement.

Account for maintenance and replacement parts

Touring cases take repeated vibration, weather, and handling, so inspect hinge, latch, rack, and fastener details before committing. Aluminum can show dents and scratches while remaining usable; ABS avoids some visible metal wear but may have different repair options if cracked. Soft bags need cleaning and drying, especially after muddy or salty rides, to protect fabric and closures. Ask whether seals, mounting brackets, keys, and hardware can be replaced individually instead of buying another full set. A little attention to spares and upkeep can matter more over time than a modest difference in stated capacity.

Frequently Asked Questions

Are universal motorcycle side cases guaranteed to fit my bike?

No. “Universal” usually describes broad intended use, not confirmed fitment on every motorcycle. Check the rack requirements, mounting points, exhaust clearance, turn-signal position, and passenger-footpeg area for your exact model and year. If the cases list support racks, verify whether those racks are included and compatible with your bike. When fitment information is vague, ask the seller for dimensions and mounting details before ordering.

Can I trust a case labeled waterproof for electronics in heavy rain?

A waterproof label is not enough to confirm performance in every downpour, especially when the listing does not explain its seals or closure design. Hard shells can still admit water at lids or latches, and soft bags depend heavily on seams and closure method. Protect electronics and documents in a separate dry bag until you have confirmed the case’s sealing performance. Check closures after packing and follow any care guidance for seals or zippers.

Should I choose aluminum hard cases or soft saddlebags?

Choose aluminum cases if rigid storage, shape retention, and a hard barrier matter more than low weight and flexibility. Soft saddlebags make more sense when you want compressible storage or a setup that may be easier to remove, but they do not offer the same rigid impact protection. Also compare mounting requirements: both styles may need bike-specific support, and soft bags must be kept clear of hot exhausts and moving parts. Your usual load, weather exposure, and storage habits should decide the tradeoff.

Do side cases with support racks included make a better purchase?

They can simplify the setup, but only if the supplied racks fit your motorcycle and meet its load requirements. A rack included in a product title may still be intended for a particular fitment or may require additional bike-specific hardware. Compare the complete mounting cost and parts list rather than treating rack inclusion as automatic compatibility. If you already own a suitable rack, a case-only option may avoid paying for hardware you do not need.

How much storage do I need for touring?

There is no single capacity that suits every trip; the right amount depends on trip length, luggage shape, and whether you carry gear elsewhere on the bike. The 50L KEMIMOTO pair gives soft-bag users more stated capacity than the 28L HI-LINE set, while compact pairs such as the 18L aluminum options suit lighter packing. A larger set can reduce overflow onto the seat but may add width and weight. Make a list of your regular load and compare case dimensions as well as total liters before choosing.

Conclusion

For a general-purpose hard-case setup, I’d start with the Tusk Aluminum Panniers V2, Large as the best overall choice in this lineup, while riders seeking a more feature-rich or refined branded option can compare the SHAD SH23 against their capacity needs. The KEMIMOTO 50L saddlebags are my best value-style pick for riders who want substantial soft storage, and the HI-LINE 28L set is a more modest soft-bag choice for lighter loads. Beginners should favor a setup with clear rack compatibility and manageable capacity over the largest cases; the 23L SHAD or a clearly compatible compact aluminum pair may be easier to live with. For specific needs, choose the 18L aluminum sets or SHAD for compact storage, GSTP’s 36L set when its rack arrangement fits your bike, and RIDEIRON’s 5L bags only as auxiliary storage. Before choosing any set, verify fitment, rack inclusion, load limits, and the actual sealing method.
