The WISECO 4T Forged Series piston kit - ø96.00mm is aimed at motocross riders looking for a reliable replacement part or a solid base for engine preparation. Made from forged aluminum, this piston benefits from Wiseco's expertise, a brand recognized for nearly half a century in the off-road competition world.
This kit is suitable for engines subjected to high stresses, typical of fast laps and jumps in motocross. The machining and finishing meet Wiseco standards for precise fitting on corresponding bores (oversize B). Ideal for replacing a worn piston or for preparing an engine with a high compression setup.
Compatible motorcycles (examples): SUZUKI RM-Z 450 (2024, 2025, 2026).
