About This Product
This MCS 25-tooth transmission sprocket fits 1980–1985 four-speed Big Twin models. A larger tooth count on the front sprocket lowers engine revs at a given road speed, reducing vibration and noise during sustained cruising. This makes the 25-tooth option well-suited to riders who regularly cover longer distances. If your existing sprocket is worn with hooked or sharpened teeth, replacement with a fresh unit protects the chain and ensures smooth, reliable power transfer. An affordable and effective way to fine-tune your Big Twin's drivetrain characteristics.
Manufacturer part number: 500580.
