Stock Top Speed Capabilities
So what’s the top speed of a bone stock Polaris Ranger 570 straight from the factory? According to owner reports, the Ranger 570 is governed to a top speed of around 44 mph depending on conditions and payload.
This speed limiter is implemented through the engine control module to balance speed capability with stability, handling, emissions, and noise. Many UTVs utilize speed limiters to meet regulations or improve safety – so the Ranger is no different.
In testing, some owners report seeing the speedometer register as high as 44 mph before the limiter kicks in to restrict further acceleration. Real world top speeds with passengers and gear match this governed limit, topping out around 44 mph on level ground.
So while not the fastest side-by-side from the factory, the stock Ranger 570 has enough governed speed capability for most owners’ needs. Those wanting more top end will need to turn to the aftermarket or a more powerful model.
Factors Impacting Top Speed
What determines how fast a side-by-side can go? There are several key factors that influence top speed:
Weight and Payload
Carrying heavier loads puts more strain on the engine to maintain speed. So passenger weight, cargo, and gear can all negatively impact acceleration and top speed if the vehicle becomes overloaded. Owners notice speed drops when approaching the Ranger’s 1,000 pound payload capacity. Shedding weight can help the Ranger reach its top speed of 44 mph.
Tire Size
The Polaris Ranger 570 comes with 25-inch tires from the factory. Moving to a larger diameter aftermarket tire can optimize torque transfer efficiency. As long as speedometer and odometer recalibrations account for larger tires, this can allow the Ranger to reach its full speed potential of 44 mph.
Engine Power
The 570cc ProStar engine produces 44 hp in stock form – adequate capability but not high performance. Modifying or upgrading the engine can directly raise the Ranger’s 44 mph top speed by producing more horsepower and torque to turn the tires faster.
How To Increase The Top Speed?
Potential modifications for increasing top speed include:
Adjust the Speed Limiter
Eliminating the speed limiter allows the engine to reach full rpm and exceed the governed 44 mph limit. Carefully test stability above 50 mph if de-restricting top speed.
Install a More Powerful Engine
Higher displacement engines like 700+cc produce 100+ horsepower which can vastly exceed the 44 mph stock top speed. Expect complex installs needing matching drivetrain upgrades.
Reduce Vehicle Weight
By reducing load weight, the Ranger 570 accelerates quicker and can potentially reach speeds closer to its limited 44 mph top speed.
Safety Considerations at Higher Speeds
While mods can unlock more straight line speed from your 570, also consider the safety impacts of faster operation:
Stability and Handling
The Ranger’s wider track width and Modular Chassis provide confident handling at stock speeds. But the higher the speeds climb, the more unwieldy any side-by-side becomes. Assess stability with speed incrementally, taking care on bumpy or uneven terrain where rollovers become more likely. Slow way down for corners.
Braking Distance
Faster speeds also mean longer stopping distances. Even with 4-wheel hydraulic disc brakes, braking performance becomes increasingly critical above 50 mph. Maintain safe following distances from other vehicles and be prepared to stop. Pay special attention braking downhill. Consider upgrading the brake system alongside drivetrain speed mods.
With thoughtful parts selection and careful acclimation to new capabilities, polaris ranger 570 speed modifications can be safe, reliable, and fast. But always prioritize control and avoid pushing your machine beyond its safe handling limits.
What Speed Can a Modded 570 Ranger Reach?
So what real world top speeds are owners seeing with modified Polaris Ranger 570 builds?
According to user reports, modded Rangers are capable of reaching:
- 50-55 mph by adjusting the factory speed limiter alone
- Low 60 mph range with intake, exhaust, clutch work, and larger tires
- 70+ mph with a 800cc engine upgrade and matched drivetrain components
Remember, stress on driveline components increases exponentially at higher speeds. Focus first on ride quality and usable power before chasing maximum dyno figures. A machine geared for 60-65 mph is often more drivable than a less balanced build topping out at 70+.

What Owners Are Saying About Polaris Ranger 570 Top Speed?
“The Polaris Ranger 570 has enough power to tow heavy loads around my property while remaining nimble on tight trails. I top out around 40 mph which suits my needs.”
“One downside is the cheap plastic doors on my model year. The poor latch design causes them to fly open over 30 mph over bumps. I reinforced the system to help retain the doors at higher speeds.”
“I use my Ranger gently on recreational trails. The ride is smooth but the stock tires and suspension handling get unstable approaching 40 mph. This model prioritizes utility use over high speed recreation.”
Key Takeaways On Your Ranger 570’S Speed
Reaching the highest top speed from the 570 requires balancing components to avoid undue strain. With careful mods, 50+ mph is possible:
- Stock Rangers reach 44 mph limited – slower while loaded
- Basic intake, exhaust and gearing changes provide modest gains
- Further engine upgrades produce more substantial increases
But most owners don’t need to transform their 570 into a race machine. Consider your real world use before performance mods. Added straight line speed rarely improves daily utility on the farm, trail or work site.
For those seeking to expand the solid Ranger platform, the 570 responds well to sensible tuning focused on reliability and control rather than peak dyno runs alone. This makes enjoying added speed much more fun!
