This kit is designed exclusively for the Yamaha YFZ 450, YFZ 450R and 450X years 2007 and up. These are top quality clutch kits that offer excellent wear resistance as well as huge holding strength. We have run these in factory race bikes as well as our Baja race bikes which must make it 1000 miles non stop--and they always make it. We are offering these at a huge savings as we introduce them into the US market. These are a bit overkill for a stock bike, but will definitely work fine and probably last forever. However, these were designed with performance in mind: big bores, strokers, etc. Bring it! new friction plates with Artrax special break-in coating to ensure even break in and at same time, helps prevent glazing. (These are not cheap cork fibers). New steel plates matched to the fibers. Hi rate spring kit with 25% stiffer springs than your stock setup.
