| Yamaha Piston Kits Our Yamaha piston kits are all quality replacements manufactured in China, Taiwan and Japan. Motorcycle & Scooter piston kits are available from stock for most makes and models from 50cc to 250cc. We do not currently supply any piston kits larger than 250cc other than the Yamaha RD350. All piston kits come complete with piston rings, gudgeon pin & circlips. Oversized piston kits and piston rings are available for rebores & big bore cylinders. Before ordering a piston kit, please check your engine for signs of a rebore by the previous owner. Check the top of your piston for any markings where possible and if not too badly damaged, as any numbers usually indicate an oversize piston. There should be an arrow as well which will point to the direction the piston should face. Piston Kits Listed are standard for standard cylinders. Unless otherwise stated, all piston kits in the following categories are of standard size, same as factory fitted. If you need an oversized piston, please send an email and request availability. If you have a Jap bike & cannot find your part on this or one of the following pages, we may have neglected to add it here or have just not yet found the time to update the category. Select your bike model from the Japanese categories to the left of this page. We also have parts for other manufacturers which you will find in the parts by type categories |
