Variator Weights Polini (x6)

CVT Weights

CVT roller weights, also called variator weights, play an essential role in the performance of scooters, maxiscooters and mopeds with CVT transmissions.

The CVT is responsible for transmitting engine power to the rear wheel of the scooter. It consists of several components, including the variator rollers. These roller weights, which are usually made of plastic or metal, sit in special tracks in the variator. Weight and diameter can vary depending on the scooter model and manufacturer.

Lighter or heavier weights?

The right weights can noticeably improve the performance of your scooter. The weight of roller weights has a direct effect on acceleration and top speed. Basically, lighter rollers lead to improved acceleration, while heavier rollers increase top speed. However, if the rollers are too light they may improve acceleration too much at the expense of speed. On the other hand, CVT rollers that are too heavy can improve speed while severely compromising acceleration.

To experiment a bit with different weights and find the best balance, we recommend getting a variator tuning kit with different weights. We also recommend buying a piston stopper or a CVT blocking tool so you can quickly disassemble and reassemble the variator.
