All of our chain sprockets are CNC machined out of billet aluminum to match each of our wheel styles.  You can choose between chrome or polished finish to give your bike that final detail to complete that custom look you have worked so hard to achieve.  Sportbike sprockets are available in 39 to 50 tooth range in 525 or 530 chain configurations. (Sprockets with matching wheel design are only available in 45-50 tooth sizes)
