Description
Factory pistons won't survive sustained high-RPM operation in a 2-stroke watercraft—thermal stress and detonation will cause catastrophic failure. The Wiseco WK1314 kit is engineered specifically for the Yamaha GP 1200 with forged aluminum construction and precision bore tolerancing to handle aggressive tuning and competitive riding. This complete piston assembly arrives ready to install, letting you rebuild your powerhead with confidence.
Wiseco's Pro-Lite design balances lightweight construction with the durability required in saltwater and freshwater environments. The high-silicon aluminum alloy resists thermal expansion, meaning consistent ring seal and reliable compression across long sessions. Whether you're refreshing a tired engine or building for race duty, this kit delivers the precision and durability that separate quality rebuilds from throwaway jobs.
