In scooters, the clutch roller or roller weight is a small cylindrical part used inside the variator / CVT drive system. It helps control the scooter’s acceleration and speed by moving inside the variator as engine RPM increases.
Even though many people call it a clutch roller, it is usually fitted in the variator assembly, not directly inside the rear clutch.
