.900" Offset Sprockets

By the mid-1980’s, Harley was using the belt drive secondaries in 100% of their Big Twins. The same 1-1/2” wide belt is still used today because it is quiet, clean, and dependable. These belts are the only way to go until you start using an engine that makes serious power. When the engine displacement is above 107ci in a decent state of tune, the life expectancy of the secondary belt is severely degraded. Furthermore, if you are running big meat on the rear you will be hooking up hard, especially in the lower gears; this will destroy your belt. Simply put, the belt drive system is not designed to transmit this amount of torque to the rear wheel and deal with the severe shock loads. In performance applications, the tried and true 530 chain driven secondary drive is the only dependable way to transmit big torque. BAKER Drivetrain offers many 530 chain size transmission drive sprockets for your performance needs for 1985-up Big Twin and 91-up Sportster/Buell. Our sprockets are made in the U.S.A.

This sprocket is the maximum offset that can be used without any modification to the stock inner primary. This makes it possible to run a 180 rear tire with no transmission offset or primary drive monkey-business required. Some rear fender modification may be required.
