MALOSSI Roller Set 19x15.5mm 9.3g - 6 Pieces (Manufacturer Ref: 66 9420.P0)
Designed by MALOSSI for scooter variators, these rollers measuring 19 x 15.5 mm are made from CPT according to a specific formula. Supplied in a pack of 6, they allow for fine-tuning of the secondary transmission behavior without heavy modifications. Ideal for riders looking to refine the acceleration and responsiveness of their scooter.
Operating Principle
The rollers act by centrifugal force: when rotating, their mass is projected outward, causing the variator to close. Heavier rollers result in an earlier gear ratio increase, while lighter rollers promote a higher engine speed before locking. This set at 9.3 g per roller is suitable for standard to light sport tuning adjustments.
Main Features
Replace worn rollers to restore a responsive throttle and smooth transmission behavior. Professional installation is recommended if you are not familiar with the variator.
