Operation and Adjustment

The rollers act by centrifugal force in the variator: as they rotate, their mass generates a push that influences the drum's travel and the gear change. In practice, lighter rollers promote a quicker rise in RPM, while heavier rollers delay this rise and lower the shift RPM. Choosing the appropriate weight allows you to adjust the RPM range to keep the engine close to its power zone according to your urban riding style.

Applications: suitable for 125 cc scooters and other compatible models. Examples: Malaguti Madison 125 (2024), Yamaha Majesty 125 S (SE81) (2016), MBK Skyliner 125 S (2016).
