Designed for a 44.96 mm standard-bore Nikasil cylinder, this kit includes the piston, piston rings, wrist pin, circlips, top-end bearing, and gasket kit needed for a complete top-end service. Manufacturer part number NX-70002-6K and vendor part number 185-70026 identify this application-specific replacement kit.\u003c\/p\u003e\u003cp\u003eThe piston uses Namura’s MOS2, or Teflon and molybdenum, coated skirts. The rolled-on coating process creates a durable bond that helps reduce friction, improve heat transfer, and 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 durability. Namura’s hypereutectic casting process provides increased silicon content for controlled expansion, added wear resistance, and improved performance under elevated cylinder temperatures.\u003c\/p\u003e\u003cp\u003eThis top-end kit is designed to fit KTM 65 SX models from 2000 through 2008, as well as the 2008 KTM 65 XC. Confirm the motorcycle year, cylinder type, and standard-bore specification before installation. The kit is intended for use with Nikasil-plated cylinders and provides the matched components required to support a reliable rebuild and proper piston-to-cylinder operation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFitment: Fits 2000–2008 KTM 65 SX models and the 2008 KTM 65 XC\u003c\/li\u003e\n\u003cli\u003eKit contents: Includes piston, rings, wrist pin, circlips, top-end bearing, and gasket kit\u003c\/li\u003e\n\u003cli\u003eSize: 44.96 mm standard-bore piston for a Nikasil cylinder\u003c\/li\u003e\n\u003cli\u003eMOS2 coating: Rolled-on Teflon and molybdenum skirt coating helps reduce friction, improve heat transfer, and minimize cold-seizure risk\u003c\/li\u003e\n\u003cli\u003eMachined smooth head: Helps reflect combustion heat and reduce carbon buildup\u003c\/li\u003e\n\u003cli\u003eAnodized dome: Increases heat resistance and piston durability\u003c\/li\u003e\n\u003cli\u003eHypereutectic casting: Provides controlled expansion, wear resistance, and improved tolerance of higher cylinder temperatures\u003c\/li\u003e\n\u003cli\u003eIdentification: Namura manufacturer part number NX-70002-6K and vendor part number 185-70026\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2000 KTM 65 SX\u003cbr\u003e\n2001 KTM 65 SX\u003cbr\u003e\n2002 KTM 65 SX\u003cbr\u003e\n2003 KTM 65 SX\u003cbr\u003e\n2004 KTM 65 SX\u003cbr\u003e\n2005 KTM 65 SX\u003cbr\u003e\n2006 KTM 65 SX\u003cbr\u003e\n2007 KTM 65 SX\u003cbr\u003e\n2008 KTM 65 SX\u003cbr\u003e\n2008 KTM 65 XC","brand":"NAMURA","offers":[{"title":"Default Title","offer_id":67559641710827,"sku":"185-70026","price":71.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/cbf1-5e989edf498eb.jpg?v=1790772753","url":"https:\/\/ctracingservices.com\/products\/namura-top-end-kit-for-ktm-65-sx-and-65-xc-44-96-mm-standard-bore-part-number-nx-70002-6k","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
