Vintco Top End Piston Kit for 125cc 2-Stroke (+1.50mm)

Elevate your motorcycle's performance with the Vintco Top End Piston Kit, specifically engineered for 125cc 2-stroke engines requiring a +1.50mm oversize bore. This comprehensive kit provides everything needed for a complete top-end rebuild, ensuring your machine runs with renewed power and reliability.

Description

The Vintco Top End Piston Kit is meticulously crafted using modern materials and advanced manufacturing techniques, guaranteeing fitment and performance that meets or exceeds OEM standards. Each forged piston, proudly made in Germany, offers exceptional strength and durability, vital for the demanding conditions of a 2-stroke engine. The piston's skirt is treated with a Molybdenum Disulfide (MoS2) coating, which significantly reduces friction during the critical break-in period, extending engine life and enhancing initial performance. Designed for a 125cc 2-stroke engine, this kit provides a 55.44mm piston diameter, corresponding to a +1.50mm oversize bore, perfect for restoring compression and power to worn cylinders. The complete package ensures a straightforward rebuild, including not just the high-quality piston, but also new rings, a wrist pin, clips, a top-end bearing, and a full top-end gasket kit encompassing head, base, intake, and exhaust gaskets. Vintco provides OEM part numbers to assist in verifying correct fitment, simplifying the selection process for your motorcycle.
