This part being universal, it may require adaptations
Set of 6 MALOSSI rollers 20x17 mm, weighing 13.5 g each (manufacturer reference: 6611095.Q0). These variator rollers are made from CPT according to a specific formula by Malossi, designed for standard replacement in variator transmissions of scooters.
Operation
The rollers transform rotation into centrifugal force: as the variator turns, the weight of the rollers pushes the weights to alter the effective diameter of the pulley. In practice, heavier rollers cause the engine to rev up earlier, while lighter rollers delay this transition — a simple mechanical adjustment to tailor the engine's behavior without modifying the mapping.
Advantages of use
These rollers are aimed at riders looking for a technically and dimensionally compliant replacement part that is useful for finely tuning the responsiveness and RPM range of their scooter. Check compatibility with your variator before installation.
