The WISECO W771M05300 forged piston is an essential component for cross preparations and engine restorations where reliability is crucial. Machined from forged aluminum, it offers controlled geometry and a finish suitable for the high demands of small displacement 2-stroke or 4-stroke engines. Designed to maintain standard compression, it fits into overbored cylinders with an oversize of +1.00 mm.
This piston is aimed at riders replacing a piston after boring or looking for an original Wiseco part for their oversized cylinder. Its forged construction minimizes the risk of deformation under load and facilitates high RPM performance without promising unverified effects. Check compatibility with your cylinder and manufacturer tolerances before installation.
