Vertex Cast Race Piston Kit for 125cc 2-Stroke Engines

Elevate your 125cc 2-stroke engine's performance with the high-quality Vertex Cast Race Piston Kit. Engineered with advanced Vertex technology, this kit delivers the durability and reliability demanded by racing and high-performance applications, ensuring your engine runs at its peak.

Description

Designed for optimal power and longevity, this Vertex Cast Race Piston Kit features a precision-engineered 53.96 mm piston diameter (54.00 mm bore size) with a race-shape profile. Each piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, significantly enhancing its strength and fatigue resistance under extreme operating conditions. The gravity cast aluminum alloy construction, with an 18% silicone content, creates an exceptionally light yet remarkably strong piston, ideal for the demanding environment of a 125 cc 2-stroke engine. Further boosting performance and lifespan, the piston skirts are coated with a high-tech Molybdenum Disulphite (Moly) coating. This advanced coating drastically reduces friction, allowing for a faster break-in time and extended piston life, while maintaining a standard compression ratio for reliable power delivery. This comprehensive kit provides everything needed for a complete piston replacement, ensuring a seamless rebuild.
