As a forged aluminum version, it combines piston compression designed for racing with a precisely defined oversize of +0.02.\u003c\/p\u003e\u003ch3\u003eDesigned for high motor loads\u003c\/h3\u003e\u003cp\u003eThe shape and design of the piston crown supports a controlled flame front and is optimized to achieve the maximum permissible compression ratio. Reinforcements stiffen the piston structure and reduce piston crown deformation under full load.\u003c\/p\u003e\u003cp\u003eA surface treatment serves to reduce friction. The short piston pin has a chamfer with a DLC (Diamond Like Carbon) coating. The locking ring with a nose on the outside counteracts twisting at high speeds. The extra-thin GNH piston ring made of gas nitrided steel increases wear resistance.\u003c\/p\u003e\u003ch3\u003eTechnical data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: VERTEX\u003c\/li\u003e\n\u003cli\u003eMaterial: aluminum\u003c\/li\u003e\n\u003cli\u003ePiston Type: Forged\u003c\/li\u003e\n\u003cli\u003ePiston compression: Racing\u003c\/li\u003e\n\u003cli\u003eDiameter Ø: 77.98 mm\u003c\/li\u003e\n\u003cli\u003eLetter oversize: C\u003c\/li\u003e\n\u003cli\u003eOversize: +0.02\u003c\/li\u003e\n\u003cli\u003eBore diameter: 78.00 mm\u003c\/li\u003e\n\u003cli\u003eRings Quantity: Set\u003c\/li\u003e\n\u003cli\u003eStroke: 4T\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVehicle assignment\u003c\/h3\u003e\u003cp\u003eSuitable for the KTM 250 EXC F, built between 2017 and 2023.
