Description

MCB Performance specializes in only engine components and rebuild kits. We've been doing this since 1994 and we refuse to sell parts that are not proven, and that are not of a standard we would use.

MCB uses Wössner pistons 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

Due to the fact that a large number of our customers do not return their cores (which depletes our inventory and cannot be re-plated for the next customer), we require you to Send Your Core to us before we release your order. Please make sure it is NOT sleeved (if it is, we can only offer to bore your cylinder, but we will not exchange a iron bore for a factory plated cylinder). Please remove to ALL fittings including studs, power valves, etc. as our cylinders are shipped completely bare. Please avoid any damage to gasket surfaces when removing these items as it could result in a repair fee.
