MCB uses Wössner pistons and crankshafts exclusively in all our MX/Off road kits. Germany's finest aftermarket forged piston manufacturer with over 25 years of experience in the Powersports / racing industry.

Wössner is currently the piston of choice for Monster Energy Star Yamaha Racing Team

Based on our experience here at MCB we feel the Wossner crankshaft is premium compared to OEM or Hotrods, and therefore our choice in this kit!
