Transmission / Clutch

Transmission, clutch and primary drive components for Harley-Davidson. This is the part of the bike that turns power into forward motion, and where a tired old Big Twin usually feels its age first.

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, and the M8 brought further changes again.

Clutch work has its own trap: a high-performance clutch that grips harder often needs stiffer springs, and stiffer springs mean a heavier lever pull unless the kit is designed around that. Kits that add a plate usually need the matching basket clearance. Read what the kit includes and what it assumes.
