NCY Clutch Spring 1500 RPM Set (Aprilia, JOG, Zuma 50)
Description: Clutch springs do a couple of things. First, they supply the pressure to engage the clutch. They also determine the rate at which the CVT transmission changes from low to high gear along assisting the compression spring. A 1000rpm clutch spring will go into a higher gear than a 1500rpm clutch spring. Color coated identifies the strength of the clutch spring, for example, a clutch spring color coated yellow is identified as 1500 RPM which will delay the clutch reaction by 1500 RPM. The greater RPM spring will provide you with greater power. NCY clutch pressure spring 1500 RPM uses a modified alloy spring providing better resilience and above-average strength for Aprilia, JOG, Zuma 50, and many other 50cc base engines.
Compatible with sport clutches on the market works on Yamaha Zuma, Minarelli Jog engines, Chinese Yamaha Clones such as the 1PE40QMB 1E40QMB engines, Malaguti, CPI, as well as Aprilia Scooters with Piaggio engines, and Franco-Morini 50cc engines found in the 1E41QMB Suzuki AD50 AG50, TGB R50X, TGB 101, TGB 303 and Peirspeed Scooters.
