This complete kit includes a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit for a convenient engine rebuild solution. The standard-bore configuration is engineered for direct fitment with compatible original-equipment cylinder specifications.\u003c\/p\u003e\u003cp\u003eThe piston features MOS2, a Teflon and molybdenum coating applied through a rolled-on process that creates a durable bond. This coating helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. A machined-smooth piston head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and durability. NAMURA uses a hypereutectic casting process that increases silicon content for controlled expansion, added wear resistance, and improved performance under elevated cylinder temperatures.\u003c\/p\u003e\u003cp\u003eFitment includes 2005–2011 and 2013 Kawasaki KVF650 Brute Force 4X4 models with SRA, plus 2002 and 2003 Kawasaki KVF650 Prairie 4X4 models with SRA.
