Yamaha YZ450F Piston Set - Wiseco - Racer Elite 14:1 CR - 2020. A purpose-built forged piston kit for the 2020 YZ450F offering a 14.01:1 compression ratio and 97.00 mm bore for performance-minded riders and builders.

This Wiseco Racer Elite piston is the first 4-stroke forged from a 2000-series alloy, engineered for greater tensile strength in full-race applications. ArmorPlating on the crown, ring groove, and pin bores defends against detonation, friction wear, and ring micro-welding, while the ArmorFit skirt coating conforms to the cylinder bore for consistent fit and reduced break-in. The kit includes high-quality rings, wrist pin, and circlips, and is manufactured, forged, and machined in Mentor, OH, USA. Intended for serious 4-stroke competition use and high-performance rebuilds on the 2020 YZ450F.
