WISECO Forged Piston - Ref. W643M04750
Wiseco forged piston designed for motocross and 2-stroke / 4-stroke engines suitable for oversized bores. Made from high-quality aluminum, this piston features a diameter of Ø 47.50 mm (oversize +0.05 mm, letter 050) and standard compression, intended for replacement during a re-bore or engine rebuild.
This piston is aimed at demanding riders who are restoring a cylinder re-bored to +0.05 mm. Its finish and tolerances meet the requirements of off-road use where assembly precision (piston/ring clearance, clearances) is essential for satisfactory engine longevity. It is advisable to replace the rings and check the pin and bearing surfaces before installation.
