VERTEX offers you this original-type piston designed for 125cc Yamaha and Fantic engines. With a diameter of 54.45 mm and a single-ring design, it offers a good balance between performance, torque and reliability.

Superior quality, it perfectly replaces the original piston without modification. Its design allows a slight increase in compression ratio, which improves engine torque, especially at low and mid-range speeds.

This model features two lubrication points to optimize lubrication and ensure longer cylinder and piston life. The skirt has also been reworked to promote gas flow and improve overall engine efficiency.

This piston is therefore ideal for optimizing the top end of the engine while maintaining excellent reliability.

Allow around 15 days for this type of piston.
