Features and Construction

Material and Build
Constructed from aluminium alloy, the piston body provides the main moving component within the engine cylinder. The piston ring features a steel strip combined oil ring cross-section design, which forms part of the combination ring structure. This construction approach separates oil control from compression functions within the ring assembly.Size and Practical Fit
With a cylinder diameter measurement of 57.4mm, the piston is designed to fit specific Honda 125cc engine applications. The total height of 37mm provides the correct piston travel dimensions within the cylinder bore. These measurements ensure the replacement component matches the original specifications for proper engine operation.Uses and Placement
