Vertex Pro HC Piston Kit Forged High Compression

Unleash the full potential of your 250cc 4-stroke engine with the Vertex Pro HC Forged Piston Kit. Engineered with Vertex's cutting-edge technology, this high compression piston kit is designed to deliver a significant boost in power and torque across the entire RPM range, transforming your ride's performance.

Description

The Vertex Pro HC Forged Piston Kit is the ultimate upgrade for riders seeking enhanced engine performance and durability. This premium piston is precision-forged from high-grade 2618 aluminum alloy, renowned for its superior strength and resilience under the most demanding conditions. Each piston undergoes a meticulous T-5 hardening and tempering cycle, ensuring maximum structural integrity and a longer lifespan. The advanced 14.4:1 compression ratio is specifically engineered to optimize combustion, resulting in a noticeable increase in horsepower and torque output for your 250cc 4-stroke engine. Furthermore, the piston skirts are treated with a high-tech Molybdenum Disulphite (Moly) coating, which not only facilitates a faster break-in period but also significantly reduces friction and wear, contributing to increased piston life. With a precise 78.97 mm piston diameter and a 79.00 mm bore size, this standard size B kit offers a perfect fit, providing everything you need for a complete installation, including the piston, rings, wrist pin, and circlips.
