VERTEX offers you this original-type piston designed for 50cc BETA and KTM engines. With a diameter of 39.5 mm and a bi-segment design, it offers a good balance between performance, torque and reliability.

High-quality, it perfectly replaces the original piston without modification. Its design allows for a slightly higher compression ratio (21.5), 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.

Available sizes:

A : 39.46 mm

B: 39.47 mm

C: 39.48 mm

D : 39.49 mm

Allow about 15 days for this type of piston.
