Upgrade your CVT performance with Dr. Pulley 20x15mm sliding roller weights. Unlike traditional round rollers that develop flat spots over time, Dr. Pulley's patented sliding geometry allows your variator to open further � delivering higher top speeds, faster mid-range acceleration, and longer service life. Made from a self-lubricating, high-temp SL-composite nylon. Sold as a set of 6.
Fitment note: Standard GY6 125/150cc engines (TaoTao, Ice Bear, etc.) use 18x14mm rollers � 20x15mm weights will not fit. Some high-end Chinese scooters with GY6-B or modified variators do accept 20x15mm. Measure your variator to confirm before ordering.
