About This Product
Zinc-plated 51-tooth rear wheel sprocket for 1973–1985 four-speed Big Twin and 1979–1981 XL Sportster models. This MCS sprocket features a zinc finish for corrosion resistance and bolts to the rear wheel hub in the standard configuration. The 51-tooth count provides the factory gear ratio for these models. If your rear sprocket has worn, hooked, or chipped teeth, replacement is essential to prevent chain skip and maintain smooth power delivery to the rear wheel. A cost-effective replacement that keeps your drivetrain running properly.
Manufacturer part number: 506420.
