This kit includes the essential components needed for a piston replacement, including a piston, rings, wrist pin, retaining clips, top-end bearing, and gasket kit. The 53.96 mm piston size and 11:1 compression specification support proper fitment and reliable engine operation when installed according to the motorcycle manufacturer's service procedures.\u003c\/p\u003e\u003cp\u003eBuilt using Namura's hypereutectic casting process, the piston provides increased silicon content for controlled expansion and improved wear resistance. The design is intended to withstand elevated cylinder temperatures while maintaining dependable performance. MOS2, or Teflon\/molybdenum, coated skirts are applied using a rolled-on process that creates a strong bond and helps reduce friction, improve heat transfer, and minimize the risk of cold seizures during operation.\u003c\/p\u003e\u003cp\u003eThe piston also features a machined smooth head to help reflect combustion heat and reduce carbon buildup, protecting the piston crown. An anodized dome increases heat resistance and durability compared with a non-anodized design. Namura manufacturer part number NX-10000-CK1 is supplied under vendor part number 185-1000C1. This top-end kit fits the 2000, 2001, and 2002 Honda CR125R.\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\u003e53.96 mm piston size with 11:1 compression specification\u003c\/li\u003e\n\u003cli\u003eMOS2 Teflon\/molybdenum-coated skirts help reduce friction, improve heat transfer, and minimize cold-seizure risk\u003c\/li\u003e\n\u003cli\u003eMachined smooth piston head helps reflect combustion heat and reduce carbon buildup\u003c\/li\u003e\n\u003cli\u003eAnodized dome improves heat resistance and piston durability\u003c\/li\u003e\n\u003cli\u003eHypereutectic casting process provides controlled expansion, increased wear resistance, and improved high-temperature performance\u003c\/li\u003e\n\u003cli\u003eFits 2000, 2001, and 2002 Honda CR125R models\u003c\/li\u003e\n\u003cli\u003eBrand: Namura\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: NX-10000-CK1\u003c\/li\u003e\n\u003cli\u003eVendor part number: 185-1000C1\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2000 Honda CR125R\u003cbr\u003e\n2001 Honda CR125R\u003cbr\u003e\n2002 Honda CR125R","brand":"NAMURA","offers":[{"title":"Default Title","offer_id":67561242886379,"sku":"185-1000C1","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/dd77-572a583cd9540_4055b754-8559-41a7-9823-b61e6594686d.jpg?v=1790774920","url":"https:\/\/ctracingservices.com\/products\/namura-nx-10000-ck1-53-96-mm-top-end-kit-for-honda-cr125r","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
