Every ounce counts when it comes to speed. Evaluate your ATV for any unnecessary components that can be removed without compromising safety. This could include extra brackets, lights, or even the stock seat in favor of a lighter aftermarket version.

Using Lighter Materials

If you’re ready to invest, consider replacing heavier stock parts with lighter materials like aluminum or carbon fiber. This not only reduces weight but can also improve handling and agility.

Tires and Suspension Upgrades

Choosing the Right Tires

Your choice of tires can greatly affect performance. Opt for lightweight, high-traction tires that are suited for the terrain you ride on. The right tires will improve grip and allow for better acceleration and cornering.

Suspension Tuning

A well-tuned suspension can make a world of difference in handling. Adjusting the preload on your shocks can help you maintain better control at higher speeds, allowing you to handle rough terrain more effectively.

Safety Considerations

While speed and performance are exciting, safety should never take a backseat. Always wear appropriate safety gear, including a helmet, gloves, and protective clothing. Modifications can change the handling characteristics of your ATV, so take the time to get familiar with how your machine responds after any upgrades.

In summary, enhancing a 90cc ATV’s performance involves a combination of engine modifications, transmission tweaks, weight reduction, and proper tire and suspension choices. Each of these elements plays a role in achieving a faster, more responsive ride.
