Set of 8 MALOSSI rollers made from CPT (specific formula) for scooter variators. Designed as a technical replacement part, these rollers allow for adjustment of the variator engagement point and fine-tuning of the engine RPM range to better meet riding needs — low-end acceleration or keeping the engine in the power zone.

Operation and Adjustment

When rotating, the mass of the rollers generates a centrifugal force that drives migration outward in the variator pulley. Heavier rollers cause an earlier RPM increase (lower engagement), while lighter rollers allow the engine to rev up before the gear change. Therefore, the choice of weight allows for adapting the scooter's character — acceleration, responsiveness, and engine behavior — according to your style and setup.
