Engineered for precision and durability, this piston kit provides an OE-quality replacement, ensuring optimal power delivery and extended engine life for your motorcycle.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Vertex Cast Replica Piston Kit is meticulously designed as an original OE form replacement, ideal for rebuilding your 250 cc 2-stroke engine. Each piston undergoes a rigorous T-5 hardening and tempering cycle, enhancing its structural integrity and resistance to extreme operating conditions. This robust heat treatment ensures that the 66.40 mm piston maintains its strength and shape under high stress, crucial for the demands of motorcycle engines. Furthermore, the piston skirts are treated with an advanced Molybdenum Disulphite (Moly) coating. This high-tech application significantly reduces friction during initial break-in, promoting faster seating of the rings and substantially increasing overall piston life. Crafted from a gravity-cast aluminum alloy with an impressive 18% silicone content, these pistons strike an optimal balance between being incredibly light and exceptionally strong. This specific alloy composition contributes to the piston's excellent thermal stability and wear resistance, making it a reliable choice for maintaining or restoring your engine's peak performance. As OEM replacements, both the replica pistons and their nitride-coated steel rings are engineered to meet or exceed original factory specifications.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOriginal OE Form Cast Replica:\u003c\/strong\u003e Ensures an exact fit and performance comparable to factory components, simplifying engine rebuilds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced T-5 Heat Treatment:\u003c\/strong\u003e Enhances piston durability and resistance to high-temperature stress, significantly prolonging engine life and reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Tech Molybdenum Disulphite Skirt Coating:\u003c\/strong\u003e Facilitates rapid and efficient break-in while substantially extending piston longevity by minimizing friction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight, High-Strength Aluminum Alloy:\u003c\/strong\u003e Gravity-cast with 18% silicone content, offering an optimal balance of minimal weight and superior structural integrity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Replacement Quality:\u003c\/strong\u003e The piston and included nitride-coated steel rings are engineered to meet or exceed original equipment specifications for dependable performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStyle: Cast Replica\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eBore Size: 66.40 mm\u003c\/li\u003e\n\u003cli\u003eEngine Type: 2-Stroke\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size B\u003c\/li\u003e\n\u003cli\u003eDisplacement: 250 cc\u003c\/li\u003e\n\u003cli\u003eProduct Name: Piston Kit\u003c\/li\u003e\n\u003cli\u003eRing Material: Nitride Coated, Steel\u003c\/li\u003e\n\u003cli\u003eSkirt Coating: Moly Coated\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 66.36 mm\u003c\/li\u003e\n\u003cli\u003ePiston Material: Aluminum Alloy, Cast\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 24384B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":62381506429258,"sku":"09105664","price":199.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/90f910861f7d11cc25e02853c46232bf_3ebf1f33-086d-47f2-88db-000941116dcc.webp?v=1781740931","url":"https:\/\/partsdenmark.com\/fr\/products\/vertex-cast-replica-piston-kit-for-66-40-mm-bore","provider":"Parts Denmark","version":"1.0","type":"link"}
