Wiseco K10741 Kawasaki 1000 Top End Forged Piston Kit 72mm Bore

The Wiseco K10741 is a complete top end forged piston kit engineered for Kawasaki 1000 engines with a 72mm bore. Built in the USA using dedicated forgings and aerospace-grade aluminum alloy, this kit delivers the performance and reliability demanded by both serious racers and powersports enthusiasts.

Wiseco's 4-stroke piston kits feature a race-ready dome finish with smooth edges for improved combustion flow and maximum power output. The ArmorGlide skirt coating reduces friction and operating noise, directly contributing to increased horsepower and extended service life. Horizontal slot-pin oiling further reduces friction and provides scuff resistance, while a pressure seal groove ensures maximum ring seal integrity.
