507050 Sportster rear brake drum & sprocket. Chrome

This chrome reproduction-style rear brake drum comes complete with a pre-installed sprocket, offering a clean and functional replacement for 1954 to 1978 K-model and XL Sportster motorcycles. It serves as a direct replacement for OEM 41401-54. As with many brake drums, even marginal out-of-round conditions can create a noticeable tight spot in the chain. Always adjust your chain at the tightest point to prevent excessive wear on the chain itself, as well as the transmission mainshaft, swingarm, and wheel bearings. A polished chrome finish gives your rear end a factory-fresh appearance while maintaining reliable braking and drive performance.
