Vertex Forged Motorcycle Engine Piston FANTIC XEF 250 [250] / FANTIC XXF 250 [250]

By equipping the best teams in world MX, Vertex has taken advantage of the fabulous test bench offered by high-level competition to develop the new range of pistons "Racer's choice". The attention to detail, aimed at improving the performance and reliability of already high-performing engines, has been pushed to its limits.

• Design and shape of the crown optimized to improve the flame front and achieve the maximum acceptable compression ratio
• Surface treatment to reduce friction
• The reinforcements stiffen the piston structure and minimize crown deformation under full load
• Short axis and chamfer with a DLC (Diamond Like Carbon) coating
• Circlips with external tab to prevent rotation at high RPM
• Ultra-thin segment "GNH" made of gas-nitrided steel increases wear resistance
