Operation and Adjustment

The rollers utilise centrifugal force: as they spin, their mass pushes the variator's nut and raises the pulley to change the gear ratio. Lighter rollers promote a higher engine speed before the gear upshift, while heavier rollers delay this upshift. Therefore, the choice of weight affects the response, acceleration, and behaviour at low and mid-range speeds.

Installation is done with a complete set of 6 rollers for simple and uniform replacement. Suitable for riders seeking a clean and reliable adjustment breakthrough on their CVT transmission, without irreversible modifications.
