WISECO 2T GP Series Piston Kit - Ø58.00 mm (manufacturer part number: W881M05800B). Forged piston designed for 2-stroke engines, intended for replacement or tuning on off-road machines. This kit follows Wiseco specifications for a precise fit in oversized cylinders and allows for restoring the piston-connecting rod assembly to spec during an overhaul.
This kit is suitable for cylinders requiring an oversize of +0.01 mm. Ideal for cross preparations where machining precision and tolerance fitting are essential for the proper functioning of transfers and squish. Before installation, check compatibility with the piston, rings, and pin provided, as well as the piston/cylinder clearance recommended by the manufacturer or your tuner.
