What do roller weights do in a CVT clutch?

Roller weights move outward in the clutch assembly as engine speed increases. This outward movement is what engages the clutch, allowing it to transfer power from the engine to the drivetrain.

Why is the weight of these rollers important?

The gram weight of the rollers directly affects when the clutch engages. Using the correct weight for your specific ATV model and riding style ensures optimal performance and smooth acceleration.

Are these weights sold individually?

No, this is a set of eight roller weights. This quantity is typically what's needed to replace all the weights in a single clutch assembly.

Product Details

This set includes eight roller weights from EPI, each weighing 14 grams. These weights are a key component in your ATV's continuously variable transmission (CVT) clutch system. They work by moving outward due to centrifugal force as engine RPMs increase, which then engages the clutch to transfer power to the wheels.

Having the correct weight for your ATV's setup is important for proper clutch operation. These 14-gram weights are designed for specific Yamaha models from 2007 and up, including the Grizzly and Wolverine X2/X4 with engine sizes ranging from 350cc to 850cc. Using the right weights helps ensure your clutch engages at the intended RPM, leading to smoother acceleration and efficient power delivery.
