Malossi Roller Set 20x12 mm — 9 g (8 pieces)
Malossi roller set made of CPT (specific formula) designed as a technical replacement for scooter variators. This pack of 8 rollers allows for precise adjustment of the primary transmission behavior: shift point, acceleration character, and maintaining engine speed within the desired range. Manufacturer reference: 66 9919.C0.
Operating Principle
The rollers rotate in the variator and, under the effect of centrifugal force, move the movable pulley to modify the effective diameter. A heavier roller generates greater centrifugal force and causes a quicker adjustment to a high ratio, while a lighter roller delays this shift and promotes higher RPMs. Therefore, the choice of weight influences the acceleration response, recovery, and usable power range.
