Yamaha MT-03 Overview
First arriving on the scene in 2006, the Yamaha MT-03 brings a sporty and naked bike design powered by a high-revving twin-cylinder engine. Part of Yamaha’s popular MT lineup also including the MT-07 and MT-09 models, the MT-03 combines lightweight agility with aggressive looks at an attractive price.
While the 321cc engine displacement may seem small at first glance, this feisty twin has a focus on top-end power and loves to scream up near its 12,500 rpm redline. The bike’s fit and finish also impress with quality components like inverted KYB forks, an aluminum swingarm and floating-mount front brake calipers.
Yamaha positions the MT-03 as an entry-level bike suited for a wide variety of riders including:
- New riders looking for their first bike
- Experienced riders seeking a nimble commuter
- Riders wanting a small-displacement canyon carver
With a rider-friendly seat height and an unintimidating price tag, the MT-03 presents an intriguing overall package. But does it have the engine performance and handling chops to make good on its sporty appearance? Let’s take a closer look at the specs.

Power and Torque from the 321cc Twin
The heart of the Yamaha MT-03 is its high-revving 321cc liquid-cooled parallel twin engine, featuring a 68 mm bore and 44.1 mm stroke. The oversquare design allows it to reach a lofty 10,000 rpm redline.
Fuel is delivered by fuel injection with a 10-hole injector. Lightweight forged aluminum pistons help it spin freely, while carburized connecting rods add lasting durability. Twin balancer shafts also help smooth out vibrations.
In stock form, the MT-03 engine produces the following horsepower and torque figures according to the specifications:
- 37 horsepower @ 10,590 rpm
- 20.2 lb-ft torque @ 9,010 rpm
While these numbers seem modest on paper, there is a good spread of power across the rev range. The twin shows good grunt right off idle yet truly comes alive once the tachometer swings past 7,000 rpm. It pulls very strongly all the way to redline, urging the rider to wring out every last rev in lower gears. There’s noticeable drive exiting corners thanks to the bike’s light 373 lb weight.
It’s been said the MT-03 is “the master of torque in the high rpm range”. There isn’t immense thrust right off idle, but given time to build revs this responsive engine delivers excitement and useable power. It offers a friendly introduction to riding high-revving twin-cylinder sport bikes.
Yamaha MT-03 Acceleration and Top Speed
The 321cc twin cylinder allows the Yamaha MT-03 to reach a governed top speed of around 108 mph – not mind blowing but reasonable for a 300cc machine. More important to real world fun is its acceleration and pickup.
Multiple tests show the MT-03 able to accomplish the 0 to 60 mph sprint in a brisk 5.11 seconds. This allows it to nip at the heels of larger displacement bikes, especially once the engine gets into its power band. Roll-on acceleration is equally as spirited.
While straight line speed isn’t the MT-03’s main mission, having the ability to joust away from a stoplight or blast up to highway pace demonstrates the engine’s willingness to work hard. There’s a satisfying surge of power near redline, and the bike feels much quicker than its 321cc displacement would suggest.
Tucking behind the windshield also improves high speed stability for short highway stints. The lack of vibration from the counterbalanced twin means the MT-03 can comfortably cruise at 80+ mph. Fuel economy remains a solid 56 mpg.
However the MT-03 is still better suited to around-town riding and backroad blasts rather than long slogs at triple digit speeds. The bike’s true performance sweet spot lies when ridden aggressively in the twisties.
Light and Nimble Handling Dynamics
A motorcycle’s speed and power is only half the equation – the handling and ride quality are just as crucial. Here again the lightweight Yamaha MT-03 impresses with its nimble chassis and suspension.
Weighing in at just 373 pounds wet with a full 3.7 gallon tank of gas, the MT-03 can be readily tossed side to side through tight switchbacks and technical sections of road. The upright riding position gives the rider good leverage and feel. Ground clearance permits reasonably deep lean angles too.
Both suspension ends offer 5.1 inches of travel, which smoothly soaks up road imperfections and keeps the wheels planted through the turns. The inverted KYB fork and preload adjustable shock perform admirably given the bike’s budget price point.
When riding the MT-03 aggressively through the twisties, the chassis remains stable and controlled. The bike turns predictably and holds its 54.3 inch wheelbase mid-corner. There is decent feedback through the handlebars and quality tires inspired confidence from the rider.
Shod with dual hydraulic disc brakes – 298 mm up front backed by a 220 mm rear unit – the MT-03 offers slowing power with good feel at the lever. Its lack of modern advanced electronics like ABS is a mild disappointment. But used prudently the binders still rein in speed well with no drama.
Overall the light weight, quality suspension and braking performance allow the MT-03’s chassis and handling dynamics to be considered as big a strength as its feisty engine. It inspires the rider push harder through the turns carrying momentum out. Add in the satisfaction of near redline upshifts exiting corners, and the MT-03 makes for smiles both coming and going!
Modifications for More Speed
While the stock Yamaha MT-03 delivers smile-inducing performance, several modifications can coax even greater speed and power from the twin-cylinder engine:
- Exhaust System: Replacing the heavy stock muffler with a lighter aftermarket unit reduces overall weight while freeing up horsepower. Expect gains around 7 hp.
- ECU Flash Tuning: Having the MT-03’s ECU professionally remapped to run more aggressive fueling and ignition timing typically releases 8-10 extra ponies.
- Intake Kit: Adding an air filter and velocity stack intake kit improves airflow into the engine yielding 3-5 hp.
- Lightweight Wheels: Swapping to premium lightweight magnesium wheels reduces unsprung weight for quicker acceleration and turn-in response.
Combining several modifications can transform a stock 37 hp MT-03 into a 50+ horsepower machine. While still not an insane power figure, on a 379 lb bike it makes for very lively performance with that peaky twin begging to scream near five-digit revs. Just don’t expect improve top speed too drastically – the MT models all seem to be governed around 108 mph.

How Does the Yamaha MT-03 Compare to Other 300cc Bikes?
The lightweight MT-03 holds its own against the field when comparing acceleration, handling and components versus key 300cc rivals:
Kawasaki Ninja 300
Very close competition as Kawasaki’s popular entry level sportbike. The Ninja edges ahead in peak horsepower at ~39 hp but the 27 pound heavier curb weight hinders acceleration. Handling and suspension are evenly matched. MT-03 has a comfort edge.
KTM RC 390
The Austrian RC 390 makes the most peak power at ~42 hp but still heavy more than the Yamaha. Very sport focused ergonomics vs the MT-03 too. Hard to split them.
Benelli 302S
Shares a similar displacement and sporty styling but the Benelli falls a bit behind everywhere else from weight to power numbers. MT-03 takes a clear win.
For new riders seeking their first bike or enthusiasts wanting a cheap speed machine, the Yamaha MT-03 deserves strong consideration. Factor in its attractive price tag and performance per dollar makes it very tempting. The MT-03 is a little rocket that punches far above its 321cc weight class!
