Description
CVT Drive Belt for GY6 50cc Engines
The 723-17.5-28 CVT Drive Belt is a key part for 50cc scooters that use the GY6 engine. Built in Japan to OEM specifications, it is designed to sit correctly and perform dependably. You can find it among the GY6 50cc scooter parts that help keep your scooter's transmission running efficiently. The belt is made from advanced synthetic rubber, which handles heat well and reduces slipping while you ride.
Construction and Performance
Inside, the belt uses reinforced tensile cords made from high-modulus synthetic fibers. These cords resist stretching and keep the belt's shape under heavy loads. Its precision-ground sidewalls support smooth, quiet shifting, so performance stays steady over time. The belt is built to last and keeps its structure even when temperatures run high, which suits a range of riding conditions.
Installation and Maintenance
Swapping out the CVT drive belt is a simple job that you can do at home. Before fitting the new belt, clean the variator and clutch parts with brake cleaner to remove any leftover rubber debris. Doing this helps the new belt perform well and last longer.
