New clutch kits for Yamaha RD250LC / RD350LC / RD350YPVS / Banshee

With so many clutch kits on the market for different power levels, our kits take the confusion out of making that choice. From a stock engine to big bores producing over 100 hp, only spring changes are needed should you increase the power at a later date.

And not only have we made it simpler, we have also made it cheaper then our previous offerings. For more more information please visit

Restocking Athena parts always feels like Christmas! With every shipment that arrives, the temptation to build an engine for ourselves gets even stronger.
