Description
Compression/Contra Spring for GY6 125-200cc Engines
This compression contra spring is designed for GY6-based engines ranging from 125cc to 200cc. It improves performance by maintaining a lower gear ratio longer, which is important for climbing and rapid acceleration. This part is one of the GY6 150cc scooter parts that can significantly improve your scooter's responsiveness. Riders seeking better acceleration and a more efficient ride will find this upgrade beneficial.
Improved Acceleration and Response
This spring increases side pressure on the CVT belt, effectively minimizing belt slip. Users will notice quicker downshifting response when the throttle is engaged. Built from heat-treated steel, it is designed to retain its spring rate even under high-temperature conditions, ensuring reliable performance.
Installation Notes
Replacing the contra spring is straightforward as it serves as a direct replacement for the driven pulley spring. However, caution is advised during installation due to the high tension of the spring. Utilize a clutch compression tool to securely manage the spring while detaching the large clutch nut.
