Sprockets Motor

26 products

Sprockets Motor for Harley-Davidson provides engine output sprockets that mate with the primary chain to transfer crankshaft power to the clutch assembly. A worn motor sprocket causes chain slap, noise and accelerated primary chain wear. Supplied through Iron City Motorcycles, an authorised Harley-Davidson dealer, this range features MCS and Evolution Industries. Whether you ride a Sportster, Softail, Dyna or classic Big Twin, you will find motor sprockets in standard and offset tooth counts manufactured from hardened steel for long service life. The correct motor sprocket ensures smooth, quiet primary drive operation and proper chain tension across all riding conditions. Browse the full range below.
