Upgrade your 250cc 4-stroke with the VERTEX Pro HC forged high-compression piston kit for stronger performance across the rev range. Built from durable 2618 forged aluminum with moly-coated skirts for faster break-in and longer life.
The VERTEX Pro HC forged high-compression piston kit is designed for riders who want a noticeable improvement in throttle response, torque and overall power delivery from their 250cc 4-stroke engine. Thanks to its high-compression design and Vertex-developed forged construction, this kit is an ideal choice for performance-focused rebuilds where strength, durability and consistent sealing matter.
By increasing compression, this piston can help your engine deliver stronger torque and improved power across the entire RPM range, making it easier to pull through corners and accelerate harder. To support reliability during demanding riding, each piston is heat-treated with a T-5 hardening and tempering cycle, while the skirt features a molybdenum disulphite (moly) coating to reduce friction, speed up break-in and extend piston life.
