This kit will replace your stock sprocket bolts, nuts and keepers with new hardware.

Many aftermarket sprockets are thinner where they bolt to the wheel and the threads on the stock bolts do not allow these sprockets to be tightened down all the way. These grade 10.9 bolts will alleviate that problem. They are the same length as the stock ones, but the threaded area is longer allowing stock sprockets or aftermarket sprockets to be securely tightened down.

The bolt keepers are genuine Yamaha replacement parts to ensure an accurate fit. It's a perfect upgrade if your keepers have been removed too many times.
