Tune your CVT engagement point with the NCY 1000 RPM clutch compression (contra) spring. The contra spring controls two things: it supplies pressure to engage the drive belt, and it determines the rate at which the CVT shifts from low to high gear. A 1000 RPM spring engages the higher gear range sooner than a higher-rated spring, making it ideal for low-end torque and urban riding. Fits most Minarelli 50cc 2-stroke applications and the Yamaha Zuma 2T. Made in Taiwan by NCY — ISO 9001 certified since 1997.
