Kawasaki KX 450 (KX 450 J) [2019-2022] - GP Racer Choice forged pistons

VERTEX GP Racer Choice forged pistons for Kawasaki KX 450

The VERTEX GP Racer Choice forged piston is designed for the Kawasaki KX 450 (KX 450 J) from the 2019-2022 model year range. Its forged aluminum design combines the piston compression intended for racing with a structurally reinforced piston structure.

Function and construction

The shape and design of the piston crown are designed to aid flame front propagation and enable a higher compression ratio. Reinforcements in the piston structure limit deformation of the piston crown. A treatment to limit friction complements the construction.

The short, chamfered piston pin has a DLC (Diamond Like Carbon) treatment. The safety clip has an external tab that prevents rotation at high engine speeds. The very thin “GNH” piston ring is made of high-strength steel.
