Malossi Roller Set 19x17mm 7.7g - 6 pieces (Manufacturer's reference: 66 9456.E0)
This Malossi roller set is designed for scooter variators as a technical replacement part. Made from CPT with a specific formula, these rollers are engineered for consistent performance in the movable pulley and offer controlled wear to maintain the transmission geometry.
Operation
The rollers utilize centrifugal force: when rotating, their mass pushes the movable pulley, altering the gear ratio and the timing of gear changes. Heavier rollers slow down the engine's RPM increase and promote a shorter gear ratio, while lighter rollers allow the engine to stay at a higher RPM.
