Designed for an 85.97 mm standard-bore application with an 11:1 compression ratio, this complete kit includes the piston, rings, wrist pin, retaining clips, top-end bearing, and gasket kit needed for a comprehensive top-end rebuild. The kit is engineered for direct fitment on 1995-2003 Honda TRX400FW Foreman 4x4 vehicles.\u003c\/p\u003e\u003cp\u003eThe piston features MOS2, or Teflon\/molybdenum, coated skirts applied through a rolled-on process that creates a durable bond. This coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures during operation. Machined smooth heads help reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine performance. The anodized dome adds heat resistance and durability, while the hypereutectic casting process provides increased silicon content for controlled expansion and improved wear resistance at higher cylinder temperatures.\u003c\/p\u003e\u003cp\u003eUse the NAMURA manufacturer part number NA-10001K and vendor part number 186-1001 when confirming application requirements. This top-end rebuild kit is intended for the following fitment: 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, and 2003 Honda TRX400FW Foreman 4x4 models.
