What do these roller weights do?

These roller weights are part of your ATV's CVT clutch. As engine speed increases, centrifugal force pushes them outward, which changes the gear ratio and affects how your ATV accelerates and reaches its top speed.

How do I know if I need 14-gram weights?

The ideal weight for your clutch rollers depends on your ATV's engine, modifications, and intended use. If your ATV feels sluggish on acceleration or isn't reaching its power band effectively, adjusting roller weight can help.

What is an 'upshift point'?

The upshift point refers to the engine RPM at which your ATV's CVT transmission begins to shift to a higher effective gear ratio. Changing the roller weight can alter this point, affecting acceleration and top-end performance.

Product Details

This kit includes a set of 8 EPI roller weights, each weighing 14 grams. These weights are a key component in your ATV's continuously variable transmission (CVT) clutch system. They work by being thrown outward by centrifugal force as the engine speed increases, which in turn moves the clutch sheaves to change the gear ratio.

By using these specific 14-gram weights, you can adjust how your ATV's clutch engages and disengages. This can help you fine-tune your ATV's upshift point, which is when the transmission starts to shift into a higher effective gear ratio. It can also help you achieve a more optimal peak engine RPM for certain riding conditions. If your ATV isn't accelerating as crisply as it used to, or if you're looking to match the clutch performance to your riding style, these weights are a straightforward way to make those adjustments.
