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.
