SCS 400 Series

The durable 400 Series centrifugal clutch, with heavey duty needle bearing, is designed and built for direct drive mini-bikes and go-karts.  These are some of the most rugged applications ever required of a modestly-priced automatic centrifugal clutch.  This clutch operates under conditions that would destroy most clutches, including sand, grit, gravel and dirt.  The SCS 400 Series is considered a “self-contained” unit but, as always, service parts are available.  This clutch will ensure many years of hassle-free use.
