KTM 450 SX-F Herlings Replica [2019] - GP Racer Choice forged pistons

VERTEX GP Racer Choice forged pistons for KTM 450 SX-F

The VERTEX GP Racer Choice forged piston is designed as a forged aluminum version for the KTM 450 SX-F Herlings Replica from 2019. Its design combines piston compression designed for racing with specifically designed details on the piston crown, piston pins and piston rings.

Function and construction

• The optimized piston crown supports an improved flame front and enables the maximum permissible compression ratio to be achieved.
• Reinforcements stiffen the piston structure and reduce piston crown deformation under full load.
• The short piston pin has a chamfer with a DLC (Diamond Like Carbon) coating.
• The locking ring with an external nose prevents twisting at high speeds.
• The extra-thin GNH piston ring made of gas nitrided steel increases wear resistance.
