Description

The Renthal Final Drive Kit is a 428 conversion kit that includes a gold Renthal R1-428 chain, a front sprocket, and a rear sprocket with stock gear ratios. This kit saves over 2 pounds compared to the stock 520 O-ring chain and steel rear sprocket. It improves acceleration and responsiveness by reducing revolving unsprung weight.
