Engineered for performance and durability, this piston kit provides a significant boost in displacement, torque, and peak horsepower, ensuring your ride delivers exhilarating power when you need it most.\u003c\/p\u003e\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eDesigned as a direct replacement in original OE form for big bore cylinders, the Vertex Cast BigBore Piston Kit is meticulously crafted from a high-quality, gravity-cast aluminum alloy with an 18% silicone content. This unique composition results in an exceptionally light yet remarkably strong piston, ideal for the demanding conditions of motorcycle engines. Each piston undergoes a rigorous T-5 hardening and tempering cycle, a specialized heat treatment that dramatically enhances its overall strength and resilience against wear and tear.\u003c\/p\u003e\u003cp\u003eTo further extend piston life and optimize break-in time, the skirts are coated with an advanced Molybdenum Disulphite finish. This high-tech coating reduces friction and wear, promoting smoother operation and sustained performance over countless miles. With a precise bore size of 67.50 mm and a +1.10 mm piston size, this kit is perfectly suited for 2-stroke 250cc engines, maintaining a standard compression ratio while delivering increased displacement. The included piston rings feature a robust Nitride Coated, Steel, and Cast material construction, ensuring reliable sealing and long-lasting operation for your high-performance piston.\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Performance Increase:\u003c\/strong\u003e Specifically designed as a big bore piston, this kit significantly increases your engine’s displacement, torque, and peak horsepower, providing a noticeable boost in overall performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Gravity-Cast Aluminum Alloy:\u003c\/strong\u003e Constructed from a high-strength, gravity-cast aluminum alloy with an 18% silicone content, offering an ideal balance of lightness and extreme durability for demanding engine environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced T-5 Heat Treatment:\u003c\/strong\u003e Each piston undergoes a T-5 hardening and tempering cycle, a critical heat treatment process that fortifies the piston's structure for superior strength and extended service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Tech Molybdenum Disulphite Skirt Coating:\u003c\/strong\u003e Features a specialized Molybdenum Disulphite coating on the piston skirts, which minimizes friction, accelerates break-in, and significantly increases piston longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOE Form Fitment:\u003c\/strong\u003e Engineered in original OE form, ensuring precise fitment and straightforward installation into your big bore cylinder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Ring Construction:\u003c\/strong\u003e Equipped with Nitride Coated, Steel, and Cast piston rings, designed for excellent sealing, reduced wear, and consistent performance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStyle: Cast Big Bore\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eBore Size: 67.50 mm\u003c\/li\u003e\n\u003cli\u003eEngine Type: 2-Stroke\u003c\/li\u003e\n\u003cli\u003ePiston Size: +1.10 mm\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, Cast\u003c\/li\u003e\n\u003cli\u003eSkirt Coating: Molybdenum Disulphite\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 67.45 mm\u003c\/li\u003e\n\u003cli\u003ePiston Material: Aluminum Alloy, Cast\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: Standard\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 22584110\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eImportant to Know\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement two-stroke piston rings are sold individually.\u003c\/li\u003e\n\u003cli\u003eFour-stroke piston rings are sold as a set.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":62381550960970,"sku":"09106703","price":196.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/53cf6eb89c255f0e0f2100e563195463.webp?v=1781742056","url":"https:\/\/partsdenmark.com\/es\/products\/vertex-cast-bigbore-piston-kit-for-2-stroke-250cc-engines","provider":"Parts Denmark","version":"1.0","type":"link"}
