VERTEX offers this replacement piston for the 477cc Big Bore top-end engine installed on the HONDA 450cc. With a diameter of 99 mm and a segmented design, it provides a good balance between performance, torque, and reliability.
Made of high-quality materials, it perfectly replaces the original piston without requiring any modifications. Its design slightly increases the compression ratio, which improves engine torque, particularly at low and mid-range RPMs.
This model features two lubrication points to optimize lubrication and ensure longer cylinder and piston life. The skirt has also been redesigned to promote exhaust gas flow and improve overall engine efficiency.
This piston is therefore ideal for optimizing the upper engine while maintaining excellent reliability.
