NCY Performance Compression Clutch Spring Yamaha Zuma 125
Black = 1000 RPM
Yellow = 1500 RPM
Red = 2000RPM
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 1000rpm spring will go into a higher gear than a 2000rpm spring. This NCY compression spring is specifically for the ZUMA 125.
