Yamaha YZ250F Piston Kit - Wiseco - Racers Elite 14.5:1 CR - `14-`15 is a complete high-performance piston kit engineered for the 2014–2015 YZ250F. This Racers Elite piston offers race-oriented materials and coatings designed for demanding 4-stroke applications.

Built from Wiseco’s Racers Elite program, this piston is forged from a 2000-series alloy to provide higher tensile strength for full-race use. ArmorPlating on the crown, ring groove, and pin bores protects against detonation, friction wear, and ring micro-welding, while the ArmorFit skirt coating conforms to the cylinder bore for optimized fitment. The kit includes high-quality rings, wrist pin, and circlips, and is engineered, forged, and machined in the USA (Mentor, OH). Intended for racers and serious tuners, it supports a 77.00 mm bore and a 14.5:1 compression ratio.
