Forged and precision-machined in the USA, this piston is designed to support durability, improved bore sealing, and increased compression potential. Its application-specific construction makes it a reliable choice for performance rebuilds and demanding powersports engines.\u003cbr\u003eThe piston dome, ring groove, and wrist-pin bore feature WISECO electra-coating for enhanced wear resistance and protection against micro-welding, galling, and detonation-related damage. This specialized treatment helps preserve critical surfaces under demanding operating conditions, supporting consistent piston performance and long service life.\u003cbr\u003eThe GP Series design generally uses less exterior machining, helping the piston seal the cylinder bore more effectively while supporting increased compression potential. An ArmorGlide® skirt coating helps reduce friction and operating noise, which may contribute to improved horsepower potential and smoother engine operation. The kit includes the piston, piston ring or rings, wrist pin, and circlips for a convenient installation package. Use the WISECO part number 767M05250 to verify compatibility with your Yamaha engine before ordering.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHigh-RPM Performance: Engineered for reliable operation in demanding, high-speed Yamaha engine applications.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eElectra-Coated Surfaces: Coating on the dome, ring groove, and wrist-pin bore improves wear resistance and helps protect against micro-welding, galling, and detonation.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGP Series Construction: Reduced exterior machining helps promote improved cylinder-bore sealing and increased compression potential.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eArmorGlide® Skirt Coating: Helps reduce friction and piston noise while supporting horsepower potential.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComplete Piston Kit: Includes piston, piston ring or rings, wrist pin, and circlips.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUSA Manufacturing: Forged and machined in the USA for dependable quality and performance.\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":60117667381534,"sku":"767M05250","price":177.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/106326.png?v=1791108552","url":"https:\/\/shoplepier.com\/products\/wiseco-767m05250-gp-series-piston-kit-52-50-mm-for-yamaha","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
