BikeMaster® sprockets and chains are meticulously engineered using the highest quality materials and industry leading technology to provide the best replacement sprockets for your motorcycle. 

BikeMaster® o-ring chain offers high durability. The controlled heat-treating process that makes them tough. Reinforced rollers have high impact resistance.

Changing the number of teeth on a sprocket changes the final drive ratio of the bike. Less rear sprocket teeth=higher top speed, more sprocket teeth=more acceleration. Select the number of teeth above.
