For durable and rugged Comet clutch parts, check out the stocks at OMB Warehouse. We offer the Comet SCS 400 series clutch with heavy-duty needle bearings. It is specially designed and manufactured for direct drive mini bikes and go-karts. This Comet clutch is one of the toughest applications ever built in an affordable and modestly-priced automatic centrifugal clutch. This Made in the USA product is rugged and works perfectly on rough terrains. The clutch runs best up to 7 horsepower and 4 cycle engines with an approximate engagement of 2000 rpm. The main advantage of the Comet clutch parts is that they can be mounted with a chain in the position of the outboard. An auto clutch like the Comet automatically engages and disengages based on the RPM of the engine and ultimately the power being transmitted to the final drive. The clutch can engage or disengage through rider input when activation of the clutch lever happens.
