This standard-bore replacement kit features a 68.45 mm piston with an 11:1 compression ratio and includes the essential components needed for a dependable top-end rebuild. The kit includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit.\u003c\/p\u003e\u003cp\u003eBuilt using NAMURA’s hypereutectic casting process, the piston provides increased silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. The piston skirt uses a rolled-on MOS2 coating made from Teflon and molybdenum. This application method creates a durable bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures during operation.\u003c\/p\u003e\u003cp\u003eThe piston also features a machined smooth head to reflect combustion heat and help reduce carbon buildup. Its anodized dome improves heat resistance and durability, offering greater strength than a non-anodized piston dome. Together, these features support consistent performance and long-term reliability in demanding recreational and utility ATV applications.\u003c\/p\u003e\u003cp\u003eManufacturer and vendor part number: NAMURA NA-10025K. Fitment includes the 1997, 1998, 1999, 2000, and 2001 Honda TRX250TM Recon with SRA suspension.
