Razor dirt bikes are designed with specific speed limits for the safety of riders, significantly younger or less experienced ones. Attempting to make a Razor dirt bike go faster by modifying its engine or components can lead to unpredictable handling and an increased risk of accidents. 

1. Check and Upgrade Batteries

The battery is the heart of a razor dirt bike, so upgrading it to a higher voltage or capacity will give you a significant speed boost. The voltage of the battery is the main factor that controls the top speed of the razor dirt bike. A higher voltage battery will give you more power and allow you to gain maximum speed. 

2. Reduce Weight

One of the critical effects of a razor dirt bike’s speed is overweight, which affects its top speed. Every pound you can cut off will make a difference, so it’s worth removing unnecessary parts and replacing heavy ones with lighter alternatives. For example, you can return the stock tires with softer tires or the stock exhaust with more lightweight exhaust. 

3. Choose the Right Tire and Upgrade

Many different tires are available on the market, so you’ll need to choose ones designed for speed. Look for tires that have a smooth tread pattern and a complex compound. The rim on your razor dirt bike can also affect the rate. If you upgrade the lighter rim, you‘ll be able to cut off some pounds, which helps the bike to go faster. 

4. Optimize Tire Pressure

The manufacturer will have a recommended tire pressure for a specific razor dirt bike. This is a good starting point, but you may need to adjust it depending on the ground you’ll be riding on. Temperature also affects the tire pressure. If the temperature is too high, the outside tire expands, and pressure will increase. The external tire contract and pressure will decrease if the temperature is low.

5. Maintain Bike Suspension

Maintaining your dirt bike suspension is essential to optimal performance and speed. By regularly inspecting, lubricating, and adjusting the suspension components, you can ensure that your bike absorbs bumps and ruts effectively, allowing you to maintain your speed and control. 

6. Gear Ratio Adjustment

When choosing a throttle, you should look for one made from durable materials with a smooth, consistent action. 

8. Install Premium Wiring

The wiring on a Razor dirt bike is one of many factors in its speed. The engine and the gearing are the primary factors determining how fast a Razor dirt bike can go. However, installing premium wiring can improve the performance of your Razor dirt bike in other ways. For example, premium wiring can help to improve the throttle response and make the bike more responsive to rider input. 

9. Install Standard Motor

The standard motor on a Razor dirt bike is a 24-volt electric motor. This motor provides enough power for the bike to reach a top speed of around 15 mph. If you install a different type of motor, such as a gas-powered motor, the bike may be able to reach a higher top speed. However, it is essential to note that the bike will also be more challenging to control and may need to be safer.
