Designed for standard-bore applications with a 66.35 mm piston, this kit is suited for engines equipped with Nikasil-plated cylinders. It provides the essential components needed for a reliable top-end rebuild, including a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit.\u003c\/p\u003e\u003cp\u003eThe Namura piston uses a hypereutectic casting process that increases silicon content for controlled expansion, added wear resistance, and improved durability under elevated cylinder temperatures. Its MOS2 Teflon and molybdenum-coated skirts are applied using a rolled-on process that creates a strong bond, helping reduce friction, improve heat transfer, and minimize the risk of cold seizure. The machined smooth head helps reflect combustion heat and resist carbon buildup, while the anodized dome improves heat resistance and piston durability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e This Namura top-end kit fits 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, and 2002 Kawasaki KX250 motorcycles.
