A worn or damaged piston costs compression and power. This piston brings that back.
A suitable new piston is required for an overhaul or cylinder replacement. Pay attention to the correct size (bore) and the position of the pin so that the piston runs smoothly and cleanly.
This part is suitable for Yamaha, Aprilia, Malaguti, etc. (with a bore of 40.5mm).
Choose the piston size that fits your cylinder and always install new piston rings and a new piston pin clip.
