This complete top-end solution includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a thorough engine rebuild. The kit is engineered for reliable fitment and performance across 1992–1999 Honda CR125R models.\u003c\/p\u003e\u003cp\u003eThe piston uses a hypereutectic casting process that increases silicon content to help reduce expansion, improve wear resistance, and withstand higher cylinder temperatures. MOS2, or Teflon\/Molybdenum, coated skirts are applied using a rolled-on process that creates a durable bond while reducing friction, improving heat transfer, and helping minimize the risk of cold seizures. The machined smooth head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and piston durability.\u003c\/p\u003e\u003cp\u003eFeature: Complete top-end kit with piston, rings, wrist pin, clips, top-end bearing, and gasket kit. Feature: 53.95 mm piston size with an 11:1 compression ratio. Feature: MOS2-coated piston skirts for reduced friction and improved break-in protection. Feature: Machined smooth piston head helps reduce carbon buildup and reflect combustion heat. Feature: Anodized piston dome improves heat resistance and durability. Feature: Hypereutectic construction supports reduced expansion and increased wear resistance. Feature: Fits 1992, 1993, 1994, 1995, 1996, 1997, 1998, and 1999 Honda CR125R motorcycles.
