Vertex Pistons 17-18 CRF 450 R/17-18 CRF 450 RX Forged GP Racers Choice Piston Kit

The Vertex Pistons 24189C is a high-compression forged piston designed for 4-stroke motocross, enduro, and supermotard engines. Developed in collaboration with GP racing teams, it offers increased torque and responsiveness.

This piston kit features a forged piston made from a high-strength alloy with a profiled dome for optimized combustion. It also includes piston rings for perfect sealing, a treated steel piston pin, and piston clips for secure mounting. The GP Racer Choice Haute compression version utilizes advanced forging and design technologies, including shot peening on the dome for improved detonation resistance and a diamond-like carbon (DLC) coated piston pin to reduce wear.
