This is the TFC Performance Variator Front Pulley Set, GY6 for 125/150cc GY6 engines.
Original Parts For Scooters SKU 179-8
Lighter weight increases acceleration throughout the rev range due to lower rotational mass. Teflon coating reduces roller wear increasing durability while the grooved sidewalls result in lighter rotational mass and increased airflow reducing heat for longer life and improved engine performance.
User-selectable rollers allow you to tune your scooter to specifically attain a higher top speed or faster launch by maintaining the ideal rpm at peak torque or peak horsepower depending on your personal preference.
