This aftermarket replacement restores compression and piston sealing, bringing back steady power and fuel-efficient combustion on rugged trails and long workdays. Built to match the original bore dynamics, the OS 1.00 rings resist wear and oil blow-by, delivering reliable seal under load. A cost-effective alternative to OEM bundles, designed for field use and dependable long-term performance. Wear and tear on the top end can creep up gradually, with ring tension loss, bore wear, and increasing oil consumption that fades power on steep climbs or heavy loads. This OS 1.00 piston ring kit is engineered to reestablish a precise seal and restore consistent combustion, so you can trust your foreman to perform when it matters most. It’s designed for rugged use in the field and on the trail, delivering reliable return-to-power without the premium OEM price.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eComprehensive Vehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModels \/ Series\u003c\/th\u003e\n\u003cth\u003eYears \/ Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 500 Foreman FA\u003c\/td\u003e\n\u003ctd\u003e2005-2019\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 500 Foreman FE\u003c\/td\u003e\n\u003ctd\u003e2005-2019\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 500 Foreman FM\u003c\/td\u003e\n\u003ctd\u003e2005-2019\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 500 Foreman FPE\u003c\/td\u003e\n\u003ctd\u003e2005-2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 500 Foreman FPM\u003c\/td\u003e\n\u003ctd\u003e2005-2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Reference Part Numbers\u003c\/td\u003e\n\u003ctd\u003e13014-HP0-A01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePiston Ring Set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAftermarket Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eHonda TRX 500 Foreman (FA\/FE\/FM\/FPE\/FPM) 2005-2019\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePiston rings manufactured for high wear resistance (cast iron common in aftermarket sets)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBore Size\u003c\/td\u003e\n\u003ctd\u003eOS 1.00 \/ Standard bore 92.00 mm (3.622\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOversize\u003c\/td\u003e\n\u003ctd\u003eOS 1.00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRing Count\u003c\/td\u003e\n\u003ctd\u003e5 rings included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackaging\u003c\/td\u003e\n\u003ctd\u003e1 kit per box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eOEM \u0026amp; Aftermarket Cross-Reference Information\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003cth\u003eBrand \/ Type\u003c\/th\u003e\n\u003cth\u003eCross-Reference Notes\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e13014-HP0-A01\u003c\/td\u003e\n\u003ctd\u003eHonda OEM\u003c\/td\u003e\n\u003ctd\u003eOEM TRX 500 Foreman piston ring set cross-reference for 2005-2019 models.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e13010-HP0-A01\u003c\/td\u003e\n\u003ctd\u003eAftermarket Replacement\u003c\/td\u003e\n\u003ctd\u003eCommon aftermarket cross-reference for TRX 500 Foreman ring sets; associated with OS 1.00 bore sizing.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eHere's what you get in the box — a ready-to-install kit designed to refresh the TRX 500 Foreman's top end.
