What PBI Sprockets Makes

PBI machines final drive gearing for Harley-Davidson - transmission sprockets, rear wheel sprockets and belt pulleys, in a range of tooth counts for changing gearing or converting a belt drive to chain. What we list from PBI Sprockets moves as the catalog moves.

Fitment

PBI Sprockets fitment is specified part by part, and coverage is not uniform across platforms or model years. Check that the fitment list on the product page names your model and year before ordering.

Know Your Gearbox

Harley Big Twins ran a five-speed through 2006 and moved to the six-speed Cruise Drive for 2007 on Touring and Dyna; those two gearboxes share very little. The Sportster runs its own unit-construction transmission entirely. Clutch work has its own trap: a clutch that grips harder often needs stiffer springs, and stiffer springs mean a heavier lever pull unless the kit is designed around it.
