This high quality accessory is the compression spring for 50cc, 125cc, and 150cc GY6 Engines from NCY. These springs are available in your choice of three ratings.
Compression springs do a couple of things. First they supply the pressure to engage the belt. They also determine the rate at which the CVT transmission changes from low to high gear. A 1000 rpm spring will go into a higher gear than a 2000 rpm spring.
Let Monster Scooter Parts be your source for NCY scooter parts and accessories.
