This 66 mm, +0.50 mm oversize kit provides the essential components for a dependable piston replacement and top-end rebuild, including a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit.\u003c\/p\u003e\u003cp\u003eThe Namura piston uses a hypereutectic casting process with increased silicon content to help reduce expansion, improve wear resistance, and withstand higher cylinder temperatures. Its MOS2 Teflon\/molybdenum-coated skirts are applied through a rolled-on process that creates a strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The machined smooth head reflects combustion heat and helps reduce carbon buildup, supporting piston protection and consistent engine operation.\u003c\/p\u003e\u003cp\u003eAn anodized piston dome improves heat resistance and durability for demanding riding conditions. The included gasket kit and related hardware make this kit a practical choice for completing a top-end service with matched components. The Namura NX-10230-2K is designed to fit 2003–2009 and 2012–2014 Honda CRF230F models.
