Description
GY6 150cc Racing Clutch Bell for 125cc–200cc Engines
This performance clutch bell is made for GY6 157QMJ-family engines between 125cc and 200cc. By lowering rotating weight, it helps the engine rev more freely and accelerate more quickly. It is one of the GY6 150cc scooter parts that help your scooter run as intended. Its design also aids in managing heat, which helps protect the drive belt during hard riding.
Improved Heat Flow
The ventilated lattice housing is built to let heat escape more effectively. Keeping the transmission cooler can help the drive belt last longer. With less heat building up, the system is more dependable when riding hard.
Grooved Inner Drive Surface
The inner drive surface of this bell is machined with grooves. These channels move friction material out of the way, which reduces slipping and stops the clutch from glazing over. The result is steady engagement and dependable operation, even under heavy use.
