Engineered for 4-stroke engines, this high-performance piston kit delivers exceptional reliability and power, ensuring a smoother, more efficient ride. Ideal for rebuilding or enhancing your engine, it provides the robust foundation needed for demanding conditions.\u003c\/p\u003e\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Wossner Pro Series Piston Kit is meticulously crafted to elevate the performance of your 250cc 4-stroke engine. Forged from aerospace-grade aluminum alloy, this piston ensures superior strength and longevity, critical for high-revving applications. Its advanced design features optimized machining that maintains robust strength in key areas like the crown and skirt wall cross-section, while simultaneously reducing overall weight for improved responsiveness. A standout feature is the permanent Molybdenum Disulphite (Moly) skirt coating, specifically engineered to significantly reduce friction, minimize piston rock, and facilitate a smoother break-in period. This results in quieter operation and enhanced power delivery. With a compression ratio of 14.1:1, this dual-ring piston is designed to maximize combustion efficiency, translating into noticeable gains in horsepower and torque. Each kit includes the piston, high-quality nitride coated steel and cast rings, a piston pin, and clips, providing a comprehensive solution for your engine rebuild or upgrade.\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\u003cul\u003e    \u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Forged Aluminum Alloy:\u003c\/strong\u003e Constructed from premium aerospace-grade aluminum alloy, ensuring exceptional strength, durability, and resistance to high temperatures and pressures for long-lasting performance.\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eAdvanced Moly Skirt Coating:\u003c\/strong\u003e Features a permanent Molybdenum Disulphite coating on the skirt, drastically reducing friction, minimizing piston rock, and aiding in a smoother, more efficient engine break-in process for quiet and improved operation.\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eOptimized Machining for Performance:\u003c\/strong\u003e Precision-machined for an ideal balance of lightness and maintained strength in crucial areas like the crown and skirt wall, enhancing engine responsiveness without compromising reliability.\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eHigh 14.1:1 Compression Ratio:\u003c\/strong\u003e Engineered with a 14.1:1 compression ratio to maximize combustion efficiency, delivering increased horsepower and torque for a more powerful ride.\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eComplete Dual Ring Piston Kit:\u003c\/strong\u003e Supplied as a comprehensive kit including the forged piston, high-quality nitride-coated steel and cast dual rings, a robust piston pin, and clips for a hassle-free installation and reliable engine rebuild.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Wossner\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Pro Series\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Piston Kit\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eVendor Part Number:\u003c\/strong\u003e 8713DC\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eMPN\/SKU:\u003c\/strong\u003e 09107090\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4-Stroke\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 250 cc\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003ePiston Material:\u003c\/strong\u003e Forged Aluminum Alloy\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003ePiston Diameter:\u003c\/strong\u003e 76.98 mm\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eBore Size:\u003c\/strong\u003e 77.02 mm\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003ePiston Size:\u003c\/strong\u003e Standard Size C\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eCompression Ratio:\u003c\/strong\u003e 14.1:1\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Dual Ring\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eSkirt Coating:\u003c\/strong\u003e Molybdenum Disulphite\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eRing Material:\u003c\/strong\u003e Nitride Coated, Steel, Cast\u003c\/li\u003e    \u003cli\u003e\n\u003cstrong\u003eUnits:\u003c\/strong\u003e Kit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381569114442,"sku":"09107090","price":220.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_5d0b720c-88fc-476f-aa37-75dc9d9ab9b2.webp?v=1781742669","url":"https:\/\/partsdenmark.com\/it\/products\/wossner-pro-series-piston-kit-for-250cc-4-stroke-engines-5","provider":"Parts Denmark","version":"1.0","type":"link"}
