About This Product
This 21-tooth transmission sprocket from MCS is a solid replacement for Ironhead owners looking to maintain their drivetrain's original performance. Designed specifically to fit 1952 through early 1979 XL Sportster models, it provides the reliable engagement you need for a smooth ride. Whether you are doing a full gearbox overhaul or just replacing a worn-out drive component, this sprocket is built to handle the torque of the classic Sportster engine. It serves as a direct replacement for OEM part number 35205-52A. Keeping your final drive in top shape is essential for preventing chain wear and ensuring efficient power transfer to the rear wheel.
Manufacturer part number: 520105.
