Vertex Pro HC Piston Kit for Forged High Compression

Unleash the full potential of your 4-stroke 250cc engine with the Vertex Pro HC forged high compression piston kit. Engineered for superior performance and durability, this kit provides a significant power and torque boost across the entire RPM range, making it an essential upgrade for serious riders.

Description

The Vertex Pro HC piston kit is meticulously engineered for 4-stroke 250cc engines, delivering a significant upgrade in power and durability. This high-compression (14.4:1) piston is forged from premium 2618 aluminum alloy, renowned for its superior strength and resilience under extreme conditions. Each piston undergoes a rigorous T-5 hardening and tempering cycle, further enhancing its structural integrity and extending operational life. The skirts are treated with an advanced Molybdenum Disulphite coating, minimizing friction during break-in and throughout the piston's lifespan, contributing to smoother operation and reduced wear. Designed to fit a 79.00 mm bore with a piston diameter of 78.96 mm (Standard Size A), this kit ensures precise fitment and optimal performance. It comes complete with the piston, high-quality rings, wrist pin, and circlips, providing everything needed for a comprehensive engine refresh or performance upgrade.
