Description
Rebuilding the top end on an 82-88 Kawasaki JS550 calls for a piston that was actually forged for two-stroke duty, and the Wiseco 516M07650 Piston Kit is sized for that exact engine.
A worn or scored piston is one of the more common reasons a two-stroke top end gets torn down, and swapping in a Classic Forged piston during that rebuild restores the fit and finish the engine needs to run cleanly again. Wiseco’s Classic Forged line covers a wide range of powersports rebuilds beyond just personal watercraft, including vintage motocross models, classic street bikes, and snowmobiles, so the same forging philosophy that suits this JS550 kit carries across other vintage two-stroke platforms. Forged construction improves tensile strength compared to a cast piston, which matters once an engine has seen years of heat cycles and hard running.
- Forged piston construction for improved tensile strength over cast pistons
- Sized specifically for the 82-88 Kawasaki JS550
- Wiseco part number 516M07650
- Dedicated forgings developed for this application rather than a generic blank
- Additional lightening operations aimed at an optimized strength-to-weight ratio
- Part of Wiseco’s Classic Forged two-stroke piston lineup
Fitted to the 82-88 Kawasaki JS550, this piston kit suits owners rebuilding a vintage two-stroke top end who want a forged piston built for that specific engine rather than a one-size-fits-all replacement.
