Engineered for superior performance and durability, this kit provides a significant power and torque boost across the entire RPM range, making it an essential upgrade for serious riders.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Vertex Pro HC piston kit is meticulously engineered for 4-stroke 250cc engines, delivering a significant upgrade in power and durability. This high-compression (14.4:1) piston is forged from premium 2618 aluminum alloy, renowned for its superior strength and resilience under extreme conditions. Each piston undergoes a rigorous T-5 hardening and tempering cycle, further enhancing its structural integrity and extending operational life. The skirts are treated with an advanced Molybdenum Disulphite coating, minimizing friction during break-in and throughout the piston's lifespan, contributing to smoother operation and reduced wear. Designed to fit a 79.00 mm bore with a piston diameter of 78.96 mm (Standard Size A), this kit ensures precise fitment and optimal performance. It comes complete with the piston, high-quality rings, wrist pin, and circlips, providing everything needed for a comprehensive engine refresh or performance upgrade.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnmatched Power Gains:\u003c\/strong\u003e Experience a significant boost in power and torque across the entire RPM range, thanks to the high 14.4:1 compression ratio, specifically designed for 4-stroke 250cc engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Durability:\u003c\/strong\u003e Forged from premium 2618 aluminum alloy, these pistons offer exceptional strength and resilience, capable of withstanding the most demanding riding conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Longevity:\u003c\/strong\u003e Each piston undergoes a T-5 hardening and tempering heat treatment, ensuring maximum structural integrity and extended operational life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Friction \u0026amp; Faster Break-in:\u003c\/strong\u003e The high-tech Molybdenum Disulphite skirt coating minimizes friction, promotes quicker break-in, and significantly increases piston lifespan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit for Easy Installation:\u003c\/strong\u003e Includes everything you need for a seamless upgrade: the forged piston, high-quality rings (Nitride Coated Steel), wrist pin, and circlips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Vertex\u003c\/li\u003e\n\u003cli\u003eProduct Name: Piston Kit\u003c\/li\u003e\n\u003cli\u003eStyle: Forged High Compression\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003eDisplacement: 250 cc\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 14.4:1\u003c\/li\u003e\n\u003cli\u003eBore Size: 79.00 mm\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 78.96 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size A\u003c\/li\u003e\n\u003cli\u003ePiston Material: Forged Aluminum Alloy (2618)\u003c\/li\u003e\n\u003cli\u003eSkirt Coating: Moly Coated (Molybdenum Disulphite)\u003c\/li\u003e\n\u003cli\u003eRing Material: Nitride Coated Steel\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eMPN\/SKU: 09106242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":62381531431242,"sku":"09106242","price":267.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/e7a3b1ab52327d0a2ae4b47a8319ae6f.webp?v=1781741459","url":"https:\/\/partsdenmark.com\/fr\/products\/vertex-pro-hc-piston-kit-for-forged-high-compression","provider":"Parts Denmark","version":"1.0","type":"link"}
