Quick-Change Hub
Definition
A rear hub system used on flat track and vintage racing motorcycles: the brake disc and sprocket mount to a carrier held on by a large knock-off nut, so parts can be changed quickly at the track. KE Motorsports sells Barnes / Kosman style carrier hubs (1″, 1-1/4″, 1-1/2″ and 1-3/4″), 10.5″ and 11.75″ discs, Vortex 520 sprockets, knock-off nuts and wrenches.
