We are pleased to announce that we are now offering Cosworth's piston kits. These are high performance pistons for the CRF250R, CRF450R and CRF450X.
Cosworth boasts these pistons as lighter and stronger than stock or other aftermarket pistons. They also feature a DLC coated pin and Xylan coating for reduced friction.
The skirt is derived from Formula One racing piston designs for high RPM's.
