100mm Big Bore Kit (Piston Kit & Cylinder Service)

100mm big bore kit for the 2003-2010 Husqvarna 450 and 510 models. The kit includes a 100mm piston kit, head gasket, and bore/re-plate services of YOUR cylinder. The forged piston is custom made by CP-Carrillo for Toxic Moto and is much stronger than a casting. The pistons feature CP's X-forging design for rigidity as well as double pin oilers to make sure the wrist pin does not go dry.
