The Honda 13102-ZE6-010 is a genuine OEM Piston (0.25) designed for GXV120 vertical shaft engines and HP400 power carriers. As an oversize piston at the 0.25 mm grade, this component is sized for engines that have been bored to that specification — always match the oversize marking to your engine's actual bore before ordering. Honda OEM construction means the piston conforms to the same dimensions and tolerances as the original, ensuring proper ring groove spacing, skirt clearance, and wrist pin alignment for the engines it serves. Confirm your serial number against the fitment table to verify this is the correct oversize grade for your unit.
Key Features
- Genuine OEM Piston Dimensions — manufactured to Honda's original bore, ring groove, and wrist pin specifications so clearances and compression are maintained exactly as designed for GXV120 engines and the HP400 power carrier
- 0.25 mm Oversize Grade — this piston is sized for an engine block that has been rebored to the 0.25 oversize; match this grade to your machinist's bore measurement before purchasing
- Correct Ring Groove Geometry — OEM ring groove dimensions ensure compatible piston rings seat and seal properly, supporting combustion pressure and controlling oil consumption
- Serial Number Verification Advised — Honda supersedes parts at production breaks, so check your engine's serial number against the fitment table to confirm part number 13102-ZE6-010 is correct for your serial range
A piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft via the connecting rod. It must fit the cylinder bore within a precise tolerance: too loose and compression leaks past the rings, causing power loss and excessive oil consumption; too tight and the piston seizes against the cylinder wall. An oversize piston like this one is used after a cylinder has been bored out to remove wear, scoring, or taper, restoring the bore to a fresh working surface. Installing the correct oversize grade is essential — a piston that does not match the rebored diameter will fail to seal or will bind, leaving the engine unable to start or run reliably.
