Clutch Assembly, Chain Sprocket, & #420 Open Loop Chain Set for Go-Karts & Mini Bikes

When you need a replacement clutch assembly with 3/4" shaft and 10 tooth 420 chain sprocket, our clutch assembly set with a chain sprocket and five feet of #420 open loop chain is an excellent choice for go-karts and mini bikes, especially for the DIY garage mechanic. Our clutch is the same style used on many offroad vehicles from Baja, Coleman, Manco, and many others. The clutch features a 3/4" shaft bore and is topped off with a pre-installed 10 tooth sprocket made for use with #420 chain.

The #420 size chain can be found on go-karts, dirt bikes, dune buggies, as well as some ATVs or other applications that typically run on 49cc, 50cc, 70cc, 110cc, or 125cc engines. We include five feet of open loop chain together with a master link. You can cut the chain to your desired length for a perfect fit. Please note that you will need to cut or otherwise shorten the chain yourself if the chain is too long for your needs.

All in all, our clutch, sprocket, and chain combination set is an outstanding value.
