Upgrade or restore your classic Honda motorcycle engine with this Standard Size Piston Kit — Japanese made with superior quality components. This kit includes a standard size piston, piston rings, and piston pin to properly rebuild one piston. Note: does not include piston pin clips (sold separately). This piston kit is ideal for engine rebuilds where standard bore pistons are required.
Because this kit includes only the components for one piston, 4 kits are typically needed to rebuild all pistons on a 4‑cylinder engine — please confirm before ordering.
Whether you’re repairing worn cylinder components or completing a full engine rebuild, trust high‑quality Japanese replacement kits for dependable performance.
