FDJ Predator 212 centrifugal mini bike clutch 12-tooth 3/4" shaft kit — iron construction, includes bolts & Allen wrench

FDJ Predator 212 Clutch 12 Tooth 3/4 is a centrifugal mini-bike/go-kart replacement clutch kit built for 3/4" shafts that includes mounting bolts, screws, and an Allen wrench for secure double fastening.

This compact centrifugal clutch is designed to convert engine power into chain-driven motion for minibikes, go-karts, and small fun karts. Machined from durable iron and engineered with a 12-tooth sprocket for 35-chain, the unit fits many 2–7 HP engines that use a 3/4" crankshaft and 3/16" keyway. The kit arrives ready to install with clutch bolts, washer, screws, and an Allen wrench so you can fasten the clutch securely to the crankshaft.
