Piston Kit (Forged High Compression)

Increase performance with a forged, high-compression upgrade. The VERTEX Pro HC Piston Kit (Forged High Compression) is designed for riders who want stronger throttle response and improved power and torque across the full RPM range. Using Vertex technology and a durable forged construction, it’s a smart choice for performance-focused rebuilds and demanding motocross/enduro use.

Because it’s forged from 2618 aluminum and heat-treated with a T-5 hardening and tempering cycle, this piston is built for strength and durability under high load. The molybdenum disulphite (moly) skirt coating helps reduce friction for faster break-in and increased service life—ideal when you want reliable performance without sacrificing longevity.
