Motorcycle Clutch

MOTORCYCLE CLUTCH COMPONENTS FOR HARLEY-DAVIDSON AND TRIUMPH BUILDS

A slipping clutch or a dragging clutch tells you the pack is worn, the springs have fatigued, or the friction plates have glazed. None of those conditions improve on their own. The clutch components collection covers replacement friction discs, steel plates, pressure plates, springs, hubs, and hardware for Harley-Davidson Big Twins and Sportsters across a wide production span, plus British Standard and Kibblewhite parts for Triumph 500, 650, and 750cc motorcycles. Whether the clutch is dragging, slipping under load, or simply due for replacement on a rebuild, the parts to address it are here.

HARLEY-DAVIDSON CLUTCH COMPONENTS

Clutch packs, springs, and hub hardware organized by platform and era:

• Clutch Plate Kits: Cycle Standard steel clutch plate sets cover Sportster applications from 1971 through current production, and Big Twin applications from 1968 through 1984. Drag Specialties steel and aramid fiber plate sets cover 1984 to 1989 Big Twins, 1998 to 2017 Big Twin and Twin Cam, and 2017 to 2023 M8 applications. Aramid fiber friction plates generally provide better heat resistance than standard organic fiber under aggressive or loaded conditions.

• Clutch Pressure Plates: The Cycle Standard 10-hole pressure plate for 1941 to 1984 Big Twins is a direct replacement for the stock plate on vintage builds. The Hawg Supply milled 4-speed pressure plate is the choice for builders who want a machined billet piece on an exposed or visible primary setup.

• Clutch Springs: Cycle Standard heavy duty spring kits for 1968 to 1984 Big Twins and Kibblewhite heavy duty spring sets for 1966 to 1984 Shovelheads provide firmer engagement than standard springs, which suits builds where slip under load is a problem. Colony adjusting springs cover early Sportster XL applications.

• Hub and Release Hardware: Cycle Standard clutch hub retainer with rollers for 1941 to 1984 Big Twins, Colony hub bearing plate springs for 1944 to 1984 Big Twins and 45-inch twins, and the American Prime Manufacturing complete master clutch kit for 1999 to 2006 Evo and Twin Cam Big Twins for builders doing a full clutch rebuild in one purchase.

TRIUMPH AND BSA CLUTCH COMPONENTS

British Standard and Kibblewhite cover Triumph and BSA clutch replacements where OEM parts are increasingly difficult to source:

• Friction and Steel Plates: British Standard clutch plates in both steel and fiber/Kevlar for Triumph and BSA motorcycles. The fiber/Kevlar version is USA-made and covers OEM specification for most Triumph and BSA applications where the stock fiber plates have worn beyond serviceable limits.

• Clutch Basket and Hub: British Standard clutch basket and chain wheel for Triumph 1960 to 1974 and the complete clutch hub center with new rubber shock absorbers for Triumph 500, 650, and 750. The rubber shock absorbers in the hub dampen drivetrain shock on engagement and are a common wear item on vintage Triumph clutches.

• Springs and Pushrods: Kibblewhite machined clutch pushrods for Triumph 650 and 750, Kibblewhite clutch spring sets for Triumph 650 twins, and British Standard clutch springs for Triumph 650 in three-piece sets.
