UMA Racing Clutch Springs - Yamaha Nouvo

The performance springs from Koso/UMA Racing are stiffer than the standard clutch springs, allowing you to pull away at higher rpms for that extra kick from standstill. Swap your original one out for this set, or are best used when paired together with the UMA Racing Clutch Shoe Kit. Comes in 3 different tensions/hardness calibrated to engage at different RPMs. Fits standard clutch shoes for the Yamaha Nouvo. White - 1000RPM Blue - 1500RPM Red - 2000RPM

Part no. MG-452
