Polaris RZR Top Speed Upgrades

The top speed of the Polaris RZR 170, which is limited to around 25 miles per, is designed to be appropriate for younger riders. However, some riders simply enjoy the thrill of driving at higher speeds and may want to modify the top speed of their RZR 170 to increase the excitement and challenge of riding.

However, it is important to emphasize that increasing the top speed of a vehicle can increase the risk of accidents and may require additional safety equipment or modifications to maintain control and stability at higher speeds.

Having said that, here are several upgrades you can make to your Polaris RZR 170 to increase its top speed;

Upgrading the Exhaust System

Upgrading the exhaust system can help increase the top speed of a Polaris RZR 170 by improving the engine’s performance. The stock exhaust system of the RZR 170 is designed to be quiet and meet emissions regulations, which can limit the engine’s power output. Upgrading to a performance exhaust system can increase the diameter of the exhaust pipes and reduce backpressure, allowing the engine to breathe more efficiently.

Improved exhaust flow can offer several benefits, including increased horsepower and torque. The engine will also be able to produce more power and operate more efficiently, which can translate to higher speeds. The upgraded exhaust system may also improve throttle response and acceleration, which can further enhance the vehicle’s overall performance.

Upgrade the Air Intake

Upgrading the air intake can help increase the top speed of a Polaris RZR 170 by allowing the engine to breathe more efficiently. The stock air intake system of the RZR 170 is designed to meet emissions regulations and provide good filtration, but it may limit the amount of air that can enter the engine.

Generally, upgrading the air intake system can improve airflow by increasing the size of the intake pipe, reducing air restriction, and providing better filtration. With an increased air intake, more oxygen is delivered to the engine, allowing it to burn more fuel and generate more power. This can lead to a noticeable increase in horsepower and torque, which can in turn help increase the top speed.

Change the Gear Ratio

Changing the gear ratio can also help increase the top speed of a Polaris RZR 170 by altering the final drive ratio between the engine and the wheels. The final drive ratio is the number of revolutions the engine turns for each revolution of the wheels. Changing this ratio can have a significant impact on the vehicle’s speed performance.

By installing a smaller front sprocket or a larger rear sprocket, the gear ratio is effectively ‘taller’, meaning that the engine will have to turn fewer revolutions to achieve a given speed. This can result in improved speed, but it may also have an impact on acceleration and low-end power.

It’s worth noting that changing the gear ratio can have both positive and negative effects on the vehicle’s overall performance. While it may lead to improved speed, it may also result in a decrease in low-end power and acceleration. Additionally, changing the gear ratio may require other modifications, such as adjusting the clutch, to ensure optimal performance.

Upgrade the Clutch

Upgrading the clutch can help increase the top speed of a Polaris RZR 170 by improving the transmission’s efficiency and power delivery. The clutch is responsible for transferring power from the engine to the transmission. As such, upgrading clutch allows it to handle more power and operate more efficiently, resulting in better performance.

A performance clutch may also have a higher torque capacity, which allows it to handle more power and reduce slippage, resulting in improved acceleration and higher speeds. Additionally, a performance clutch may have different clutch weights or springs, which can affect the engagement and disengagement of the clutch and improve the transmission’s efficiency.

Upgrading the clutch can also be beneficial when other modifications, such as changing the gear ratio or upgrading the exhaust or air intake, have been made. These modifications can increase the power output of the engine, but they may also put additional stress on the clutch, causing it to slip or wear more quickly. Upgrading the clutch can help ensure that the transmission is able to handle the increased power output and operate more efficiently.

ECU Tune

Apart from upgrading the clutch, an ECU tune can help increase the top speed of a Polaris RZR 170 by modifying the engine’s fuel and ignition systems to optimize its performance. The ECU controls various aspects of the engine’s operation, including fuel delivery, ignition timing, and throttle response.

By modifying these settings, an ECU tune can improve the engine’s power delivery and efficiency, leading to increased horsepower and torque, which in turn, helps to increase the top speed.

ECU tuning can also help eliminate some of the restrictions that may be present in the stock engine programming, such as speed limiters or emissions controls that can limit the engine’s performance. This can result in improved throttle response and acceleration, as well as improved speed.

Removing the speed limiter

The speed limiter is a safety feature that is built into the vehicle’s electronic control module and is designed to limit the vehicle’s maximum speed. When the speed limiter is in place, the vehicle’s engine is prevented from reaching its full power output, thereby restricting the vehicle from attaining maximum speed. By removing the speed limiter, the engine is able to produce more power, allowing your vehicle to reach higher speeds.

However, RZR 170 speed limiter removal can be a dangerous move, as it can lead to excessive speeds and loss of control. Additionally, removing the speed limiter may void the vehicle’s warranty and can have legal implications, depending on the jurisdiction. If you are considering removing the speed limiter on your Polaris RZR 170, it’s important to do so only after carefully weighing the potential risks and benefits.
