Engineered for demanding race conditions, this high-performance piston kit delivers superior power, strength, and durability for serious riders seeking a competitive edge.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThis Vertex GP Racer's Choice 250cc 4-Stroke Piston Kit is meticulously designed to optimize your engine's output. Featuring advanced T-box forgings and unique dome profiles, these pistons are engineered to achieve increased compression ratios, translating directly into enhanced power and responsiveness on the track or trail. Each piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, ensuring exceptional strength and extended durability under extreme operating conditions. The robust construction utilizes premium 2618 forged aluminum alloy, a material renowned for its superior strength-to-weight ratio, making it ideal for high-performance applications. Furthermore, the piston skirts are meticulously coated with a high-tech Molybdenum Disulphite (Moly) coating. This advanced surface treatment significantly reduces friction during initial break-in, accelerating the process and contributing to a longer overall piston lifespan. Designed for a 78.00 mm bore, this standard size D piston kit is a direct fit for your 250cc 4-stroke engine, providing a reliable and powerful upgrade.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Power Output:\u003c\/strong\u003e Engineered with advanced T-box forgings and unique dome profiles to achieve increased compression ratios, delivering superior power, strength, and overall engine durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Durability:\u003c\/strong\u003e Each piston undergoes a T-5 hardening and tempering heat treatment cycle, ensuring maximum strength and resistance to wear in demanding racing environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Friction \u0026amp; Longevity:\u003c\/strong\u003e High-tech Molybdenum Disulphite (Moly) coated skirts facilitate faster break-in and significantly extend piston life by minimizing friction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Forged Construction:\u003c\/strong\u003e Crafted from high-strength 2618 forged aluminum alloy, providing exceptional structural integrity and reliability for high-performance 4-stroke engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit for Installation:\u003c\/strong\u003e Includes everything needed for a comprehensive piston replacement: the piston, high-quality rings, wrist pin, and circlips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePiston Style: Forged Race\u003c\/li\u003e\n\u003cli\u003eBore Size: 78.00 mm\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003eDisplacement: 250 cc\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 77.98 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size D\u003c\/li\u003e\n\u003cli\u003ePiston Material: Forged 2618 Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eRing Material: Nitride Coated Steel\u003c\/li\u003e\n\u003cli\u003eSkirt Coating: Molybdenum Disulphite (Moly)\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: Standard\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":62381559382346,"sku":"09106758","price":1277.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/69c187f69cc36cfb4ad5b8d97c3d7e8a_577d8ffe-7b60-41ec-bcdc-917d78928ee5.webp?v=1781742192","url":"https:\/\/partsdenmark.pl\/products\/vertex-gp-racers-choice-piston-kit-for-250cc-4-stroke-1","provider":"Parts Denmark","version":"1.0","type":"link"}
