A forged piston moves heat better and tolerates detonation far better than the cast slug that came in it from the factory, which matters on an air-cooled engine and matters even more on a machine that has been sitting in a shed for thirty years. The forging design and skirt profile are built to make real horsepower and torque rather than just fill a bore, and every kit ships complete with the rings, wrist pin and circlips you need to close the top end back up. If you are rebuilding a vintage three-wheeler or an old dune machine, this is the part that decides whether it runs for one season or for twenty. Made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e This is an oversize piston. Your cylinder must be bored to 71.00mm before this will fit.
