Yamaha YZ125 Piston Set - Wiseco - Racers Elite - `05-`20. A complete Racer(s) Elite piston kit engineered for full-race 2-stroke YZ125 applications, offering forged construction and protective surface treatments for demanding use.

Designed for riders who prepare race engines or high-performance rebuilds, this Wiseco Racers Elite kit uses a 2000-series alloy forging to increase tensile strength versus conventional pistons. ArmorPlating is applied to the crown, ring groove, and pin bores to help guard against detonation, friction wear, and ring micro-welding, while the ArmorFit skirt coating conforms to the cylinder bore to improve fit and reduce break-in issues. The kit is engineered, forged, and machined in Mentor, OH, and ships with high-quality ring(s), wrist pin(s), and circlips for straightforward installation.
