About This Product
This 30-tooth transmission pulley is the standard replacement for many 1200cc Sportster models, offering the correct final drive ratio for highway speeds and smooth power delivery. It fits 2004 to 2022 XL Sportsters and 2008 to 2012 XR1200 models, replacing OEM references 40379-04 and 40380-04. For owners of 883 models looking to lower their RPMs at cruising speeds, swapping to this 30-tooth pulley is a popular modification. Manufactured by MCS to meet original equipment specifications, this pulley is built to withstand the torque of the Evolution V-twin engine. It is an essential part for any transmission service or gearing adjustment, ensuring your belt drive system operates quietly and efficiently. Proper installation will help maintain belt life and ensure your Sportster performs exactly as it should.
Manufacturer part number: 520112.
