Vertex Piston 24381A piston kit

VERTEX PISTON 24381A Piston Kit (Pro HC) for Yamaha YZ 250 F

Elevate your engine´s performance to the next level with the VERTEX PISTON 24381A Piston Kit, a premium top-end solution engineered for riders who demand maximum power and uncompromising reliability. Specifically designed as a high-compression upgrade, this Pro HC kit is the definitive choice for transforming your motorcycle´s engine heart, delivering a tangible competitive edge on the track or trail.

Developed using Vertex´s world-renowned technology, the Pro HC forged piston is meticulously crafted to increase compression. This results in a significant improvement in power and torque across the entire RPM range, providing sharper throttle response and stronger acceleration out of corners. The superior strength and durability of the piston come from its 2618 aluminum alloy construction, a material trusted in the highest echelons of motorsport for its exceptional performance under extreme heat and pressure.

Every piston undergoes a critical T-5 hardening and tempering heat treatment cycle. This process ensures optimal structural integrity, providing peace of mind and consistent performance throughout its service life. To further enhance its capabilities, the piston skirts feature a high-tech Molybdenum Disulphite (MoS2) coating. This advanced layer minimizes friction against the cylinder wall, which not only allows for a faster and more effective break-in period but also substantially increases the overall lifespan of the piston.

This comprehensive kit provides everything needed for a professional-grade top-end rebuild. It includes the precision-engineered piston, high-quality rings, a durable wrist pin, and circlips. Whether you are refreshing a tired motor or seeking a powerful upgrade, the Vertex 24381A kit offers a complete, race-proven package.
