British Customs engineered this retro-style sprocket to capture the vintage Triumph look of the ‘60s while delivering an unparalleled twenty-first century performance product. Machined from 7075 T6 aluminum billet and available in a raw, polished or textured black finish, it’s a direct replacement for the stock 43-tooth sprocket. The British Customs Retro Sprocket is lighter, stronger and sexier than your bike’s OEM model, and it complements our Modern Classic Chain Guard and Countershaft Sprocket Cover perfectly.
