Manufactured from gravity-cast aluminum alloy with 18% silicone content, this piston is engineered to provide consistent performance, dependable fitment, and durability for demanding off-road use. The kit is intended for refreshing the top end while helping restore proper engine response and operating efficiency.\u003cbr\u003eThe piston receives a T-5 heat-treatment hardening and tempering cycle to improve strength and service durability. Its skirt features a high-tech molybdenum disulfide coating that helps reduce friction during initial operation, supports faster break-in, and contributes to extended piston life. This coating and heat-treatment process make the Vertex piston a practical choice for riders and technicians seeking dependable replacement components without switching to a forged piston design.\u003cbr\u003eEach Vertex VTK22813CD top end kit includes the essential components for installation: one cast piston, piston rings, wrist pins, circlips, top-end gaskets, and a wrist-pin bearing. Supplied as a complete package, the kit helps simplify top-end service and keeps the required replacement parts together for a more efficient rebuild. Verify vehicle application and service specifications before installation to ensure proper compatibility and assembly.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Vertex\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: VTK22813CD\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: KTM 50 SX and SX Pro Jr.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston Type: Cast OE replacement piston\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaterial: Gravity-cast aluminum alloy with 18% silicone content\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeat Treatment: T-5 hardening and tempering cycle\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSkirt Coating: Molybdenum disulfide coating for faster break-in and reduced friction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eKit Contents: Piston, rings, wrist pins, circlips, top-end gaskets, and wrist-pin bearing\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":60117727150366,"sku":"VTK22813CD","price":125.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/409979.png?v=1791111039","url":"https:\/\/shoplepier.com\/products\/vertex-vtk22813cd-top-end-piston-kit-for-ktm-50-sx-and-sx-pro-jr-39-47-mm","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
