KTM 250 EXC-F Factory Edition [2015] - GP Racer Choice forged pistons

VERTEX GP Racer Choice forged pistons for KTM 250 EXC-F Factory Edition

The VERTEX GP Racer Choice forged piston is designed as a forged racing version made of aluminum for the KTM 250 EXC-F Factory Edition from 2015. Its design was developed with a focus on precise combustion, low friction and a resilient piston structure.

Function and design features

• The optimized shape of the piston crown supports a favorable flame front and the achievement of the maximum permissible compression ratio.
• A treated surface reduces friction during operation.
• Reinforcements stiffen the piston structure and reduce piston crown deformation under full load.
• The short piston pin has a DLC (Diamond Like Carbon) coating.
• The locking ring with an external nose counteracts twisting at high speeds.
• The extra-thin GNH piston ring made of gas nitrided steel increases wear resistance.
