This kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a comprehensive rebuild solution. The 54.94 mm piston size and 11:1 compression ratio are designed for the specified application and provide a precise fit when rebuilding the engine.\u003c\/p\u003e\u003cp\u003eThe Namura piston uses a hypereutectic casting process with increased silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2, or Teflon\/Molybdenum, coated skirts use a rolled-on application process that creates a durable bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The anodized dome adds heat resistance and durability, while the machined smooth head helps reflect combustion heat and reduce carbon buildup.\u003c\/p\u003e\u003cp\u003eThis Namura top-end kit fits 1992-1999 Honda CR125R models, including model years 1992, 1993, 1994, 1995, 1996, 1997, 1998, and 1999. Verify the motorcycle model year, cylinder condition, and required piston size before installation. The manufacturer part number is NX-10000-4K, and the vendor part number is 185-10004.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eComplete top-end kit: Includes piston, rings, wrist pin, retaining clips, top-end bearing, and gasket kit\u003c\/li\u003e\n\u003cli\u003ePiston size: 54.94 mm piston for the specified Honda CR125R application\u003c\/li\u003e\n\u003cli\u003eCompression ratio: 11:1 design for compatible engine configurations\u003c\/li\u003e\n\u003cli\u003eMOS2-coated skirts: Rolled-on Teflon\/Molybdenum coating helps reduce friction, improve heat transfer, and minimize cold-seizure risk\u003c\/li\u003e\n\u003cli\u003eMachined smooth head: Reflects combustion heat and helps reduce carbon buildup\u003c\/li\u003e\n\u003cli\u003eAnodized dome: Improves heat resistance and piston durability\u003c\/li\u003e\n\u003cli\u003eHypereutectic construction: Higher silicon content helps control expansion and increase wear resistance\u003c\/li\u003e\n\u003cli\u003eFitment: Fits 1992-1999 Honda CR125R models\u003c\/li\u003e\n\u003cli\u003eBrand: Namura\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: NX-10000-4K\u003c\/li\u003e\n\u003cli\u003eVendor part number: 185-10004\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n1992 Honda CR125R\u003cbr\u003e\n1993 Honda CR125R\u003cbr\u003e\n1994 Honda CR125R\u003cbr\u003e\n1995 Honda CR125R\u003cbr\u003e\n1996 Honda CR125R\u003cbr\u003e\n1997 Honda CR125R\u003cbr\u003e\n1998 Honda CR125R\u003cbr\u003e\n1999 Honda CR125R","brand":"NAMURA","offers":[{"title":"Default Title","offer_id":67561445392619,"sku":"185-10004","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/dd77-572a583cd9540_6542c05b-4e93-4211-970a-dfbf72deda85.jpg?v=1790775048","url":"https:\/\/ctracingservices.com\/products\/namura-nx-10000-4k-top-end-kit-54-94-mm-11-1-compression-for-honda-cr125r","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
