KAWASAKI KX 450 X [2023] - GP Racer Choice forged pistons

VERTEX GP Racer Choice forged pistons for the KAWASAKI KX 450 X

The VERTEX GP Racer Choice forged piston is designed as a forged aluminum piston with racing compression for the KAWASAKI KX 450 X from 2023. Its optimized piston crown shape supports a more favorable design of the flame front and higher compression.

Function and construction

• The optimized shape and design of the piston crown improves the spread of the flame front and supports a higher compression ratio.
• Treatment reduces friction.
• Reinforcements increase the stability of the piston structure and limit the deformation of the piston crown.
• The short, chamfered piston pin has a DLC (Diamond Like Carbon) treatment.
• The external nose locking clip prevents twisting at high engine speeds.
• The particularly thin GNH piston ring is made of high-strength steel.
