Lightened fourth generation racing clutch from NCY. With extra lightweight pillows and high friction pads, this is a great upgrade for a stock or performance machine. The light weight pillows allow for quicker spool and higher revvs. 
 Fits most Yamaha platform engines from 50-100cc that take a 107mm clutch. Minarelli engines used a couple of different sizes of clutch bells throughout the years. Please verify your original size before ordering.
