Designed for dependable top-end service, this kit includes the essential components needed to replace the piston assembly and refresh the cylinder top end. The 66.35 mm piston is gravity-cast from an aluminum alloy containing 18% silicon, providing a durable and consistent foundation for reliable engine performance.\u003cbr\u003eThe piston is heat treated using a T-5 hardening and tempering cycle to support strength and durability under demanding operating conditions. Its skirt features a high-tech molybdenum disulfide coating, which promotes faster break-in and helps reduce friction during initial operation. This coating also contributes to extended piston life when the engine is properly assembled, lubricated, and maintained according to manufacturer recommendations.\u003cbr\u003eThe Vertex VTK22650B-2 kit is supplied with a piston, piston rings, wrist pin, circlips, top-end gaskets, and wrist pin bearing. By packaging these key components together, it helps streamline top-end replacement and supports a thorough repair rather than replacing individual parts separately. Verify engine compatibility and service requirements before installation to ensure the correct fit and proper assembly.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eApplication: Compatible with KTM EXC250 models requiring a 66.35 mm top-end piston\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstruction: Gravity-cast aluminum alloy piston with 18% silicon content\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTreatment: T-5 heat-hardening and tempering cycle for improved durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCoating: Molybdenum disulfide-coated piston skirt for faster break-in and reduced friction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eKit Contents: Includes piston, rings, wrist pin, circlips, top-end gaskets, and wrist pin bearing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplacement Type: Cast original-equipment replacement piston kit\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":60117726527774,"sku":"VTK22650B-2","price":256.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/409939.png?v=1791110969","url":"https:\/\/shoplepier.com\/products\/vertex-vtk22650b-2-top-end-piston-kit-66-35-mm-for-ktm-exc250","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
