Top Speed Polaris Sportsman 570
The Polaris Sportsman 570 was introduced in 2005 and since then, the model has been further developed and improved. The top speed of the reigning year is the same as the top speed of this year models, and the acceleration power is the same as well.
Polaris Sportsman 570 features a 567cc mill generating 44 horsepower and good torque across the rev range. The CVT transmission is well-tuned for quick accelerations while remaining smooth and increasing the rpm at a well-tiered rate. The Polaris Sportsman 570 top speed is factory set at 63 mph, but some have gone faster, attaining 67 mph. The acceleration from 0 – 60 mph is 11,5 seconds.

Sportsman 570 Topspeed Compared To Other Polaris Models
Curious to see how fast the 570 is compared to other Polaris Sportsman models? The table below gives you a quick overview of the different top speeds. Keep in mind that these numbers are averages of the factory specs, as well as several speed tests, found on YouTube.
| Sportsman | Top Speed (mph) |
|---|---|
| 570 | 63 |
| 450 | 55 |
| 500 | 63 |
| 850 | 66 |
| 1000 | 70 |
As to been expected, the Sportsman 1000 has the fastest top speed in the Sportsman range.
How Fast Is The Sportsman 570 Compared To Other ATVs?
Let’s also compare the Sportsman 570 to its competition. Keep in mind that the top speeds of these models are taken from the standard version, the special versions are not listed in the table.
These speeds also come from the technical specifications and various YouTube videos, and are average top speeds.
| Model | Top Speed (mph) |
|---|---|
| Sportsman 570 | 63 |
| Yamaha Grizzly 600 | 60 |
| Can Am Outlander 570 | 62 |
| Honda Rancher 420 | 55 |
| Honda Rubicon 500 | 54 |
| Honda Foreman 500 | 50 |
| Kawasaki Brute Force | 70 |
| CF Moto Cfore 520 | 56 |
As you can see, the Sportsman 570 is definitely one of the faster options, at times with 8 mph. Still, if you’re only looking at speed, however, the Kawasaki Brute Force is probably your best choice. Unsurprising, with a name like that.

How To Make Your Polaris Sportsman 570 Faster?
By ramping up the engine and engine related parts, the Polaris sportsman 570 will definitely reach a higher top speed. However, keep in mind that the ATV is not designed for this, which can cause more wear and tear, resulting in more frequent maintenance.
If you still have factory warranty on your Sportsman 570, I advise against ramping it up. Making changes to your Polaris could void the warranty, meaning if you run into any major issues, you’ll likely have to pay for those yourself. So, first check your warranty before you make the alterations.
There are several ways to make the Sportsman 570 faster, (but remember, this is at your own risk) including:
1. Use Better Fuel
An easy and quick increase in the speed of your Sportsman 570 is by using higher octane fuel. The higher-octane fuel can help boost the performance of your engine. The fuel burns cleaner, improving your fuel economy and reducing corrosion of the mechanical components of your fuel system. You will notice the performance differences, even though the better mileage isn’t particularly visible. You will pay a little bit more for it than the cheap fuel, but you will appreciate the difference when you slam on the gas.
Some riders decide to increase the octane level in their fuel themselves because they desire an even bigger boost than what is available at a gas station. You can simply add a small amount of the gas in your Sportsman 570 and rock it back and forth to mix it up a little. You can pre-mix it in a gas can before adding it to the gas tank to ensure that your measurements are accurate.
2. Upgrade the Intake
Regularly inspecting and cleaning your air filter are recommended. A clogged air filter restricts the amount of air reaching the engine. So, riding with a clogged air filter is the equivalent of choking or suffocating your engine. You can also replace your stock air filter with a high-flow air filter. K&N has been producing some of the best air filters for use in almost any type of Power sport or automotive application for decades.
The upgrade intake allows increased airflow to the engine; it means more air-fuel mixture, translating to more power. It is one of the easiest ways to increase the performance of your machine. K&N high-flow air filters range from $29.87 to $129.99.
3. Tweaking the Engine Control Module
The speed limit of the Polaris Sportsman 570 is set in the engine control unit (ECU). You can remap or reflash the ECU to remove the speed limits, raise the RPM and gain more power. Also, you can use an aftermarket ECU flash to disable the speed limiter.
4. Change Tire Size, Pressure, and Weight
Choose a larger tire if you want more top speed. Choose a larger tire if you wish to accelerate faster. Larger tires require more power to turn, but cover more distance per revolution. Tire pressure plays a role depending on the terrain. A lower tire pressure makes you faster when riding in sand or snow, while higher tire pressure helps more on flat, hard surfaces.
Further, the popular combination of steel rim with big heavy mud tires usually affects the speed of your quad. If you want to make your Sportsman 570 faster, consider getting lightweight aluminum rims and a nice set of performance tires. Choose the tire size depending on your playground or interest.
5. Fit a Nitrous Kit
Fitting your ATV with a nitrous kit can help when you need a boost in speed. There are several various nitrous configurations, such as wet and dry. Go for a setting that makes you feel secure. The kits are easy to install or use, and many people employ them to get some extra speed.
6. Upgrade the Exhaust
Upgrading the exhaust on your Polaris Sportsman 570 is a surefire way to boost the performance of your quad. But the exhaust upgrade can be expensive and labor-intensive. The engine can draw in more air because it can expel more air. This configuration works well when used in parallel with a high-flow air intake system.
A performance slip-on exhaust is an excellent option if you can’t replace the full exhaust system from the headers down. The slip-on muffler is the most popular system because they allow you to remove your factory muffler and replace it with one that is often lighter. These systems also have cores that enable far higher exhaust flow rates than the stock systems’ substantially baffled ones.
The performance slip-on exhaust gives you more horsepower, but not as much as a full-performance exhaust system. You can combine a high-flow intake system with the slip-on or full systems for maximum performance gains.
Typically, performance exhaust systems have a larger diameter than stock or are formed like cones and gradually increase in diameter. It allows more air can to pass through the engine. The richer air-fuel mixture increases power and speed. Slip-on mufflers range from $1 89.94 to 350.96.
7. Install a Big Bore Kit
The performance increase from installing a big bore kit can be substantial. Top speed will rise along with acceleration speed. In essence, you are increasing your engine’s cubic capacity. You will be swapping out the piston and cylinder with a larger size with most larger bore kits. Your Sportsman 570 will perform much better because more air, fuel, and mixture enter the combustion chamber. Big Bore Cylinder Kit cost $458.91 to $1,099.95
