What does a secondary spring do for my ATV?

The secondary spring is part of your ATV's clutch system. It works with other components to control when your clutch engages and helps determine your engine's maximum RPM, allowing you to customize performance for different riding conditions.

Why is the 5% tolerance important?

A tight tolerance, like the 5% EPI uses, means the spring's performance will be very consistent. This leads to more reliable clutch engagement and predictable performance, which is important for both trail riding and demanding terrain.

Does this spring come with other clutch components?

This product listing is for one EPI Secondary Spring, color-coded maroon. It is sold individually and does not include other clutch parts like weights or primary springs.

Product Details

This is the EPI Secondary Spring, color-coded maroon, designed for specific Kymco ATV models. You get one spring in this package, which is a key component for fine-tuning your ATV's clutch system. It helps you adjust when your clutch engages and what your engine's top RPM can reach, letting you match your machine's performance to how and where you ride.

EPI makes these springs with a tight tolerance of just 5%, which is the lowest in the industry. This means you can count on consistent performance every time. At 2.2 inches, it applies a load of 160 lbs, and at 1.1 inches, it's 260 lbs. This level of precision helps ensure your clutch responds reliably, whether you're crawling over rocks or hitting open trails.
