Engineered for superior performance and exceptional durability, this high-performance piston kit is meticulously crafted to deliver a significant upgrade to your motorcycle's power and reliability.\u003c\/p\u003e\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Wossner Standard Series Piston Kit is the ultimate choice for riders seeking enhanced engine performance and longevity. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring unparalleled strength and the ability to withstand the extreme demands of high-revving 4-stroke engines. With an optimal 97.95 mm piston diameter, this kit is designed for a 640 cc displacement engine, providing a precise fit and reliable operation.\u003c\/p\u003e\u003cp\u003eA key feature is the advanced Molybdenum Disulphite (Moly) skirt coating, applied permanently to reduce friction and minimize piston rock. This not only contributes to quieter engine operation but also significantly improves overall performance and aids in the critical break-in process. The optimized machining ensures maximum lightness without compromising strength in crucial areas like the crown and skirt wall cross-section. The kit includes everything needed for a complete piston overhaul: the forged aluminum alloy piston, high-quality Nitride Coated, Steel, and Cast piston rings, a durable piston pin, and secure clips, all designed for long-lasting engine reliability.\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Performance \u0026amp; Quiet Operation:\u003c\/strong\u003e Features a permanent Molybdenum Disulphite (Moly) skirt coating that significantly reduces friction and piston rock, leading to quieter engine performance and improved efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Strength \u0026amp; Durability:\u003c\/strong\u003e Forged from aerospace-grade aluminum alloy, this piston kit is engineered for exceptional resilience and longevity, capable of withstanding the most demanding 4-stroke engine conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Lightweight Design:\u003c\/strong\u003e Precision machining ensures the piston is as light as possible for improved responsiveness, while maintaining critical strength in the crown and skirt wall cross-sections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Piston Kit:\u003c\/strong\u003e Comes as a comprehensive kit including the high-quality forged piston, Nitride Coated, Steel, and Cast piston rings, a robust piston pin, and secure clips for a straightforward installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Wear \u0026amp; Extended Engine Life:\u003c\/strong\u003e The advanced skirt coating not only aids in break-in but also provides long-term friction reduction, contributing to reduced engine wear and an extended lifespan for your 640cc 4-stroke motor.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Wossner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Standard Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Piston Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4-Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 640 cc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Material:\u003c\/strong\u003e Forged Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Diameter:\u003c\/strong\u003e 97.95 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Size:\u003c\/strong\u003e Standard Size B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSkirt Coating:\u003c\/strong\u003e Molybdenum Disulphite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Material:\u003c\/strong\u003e Nitride Coated, Steel, Cast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnits:\u003c\/strong\u003e Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVendor Part Number:\u003c\/strong\u003e 8522DB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381565837642,"sku":"09107037","price":251.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_95f4c31c-eec0-41db-a56d-b14c3d30a25c.webp?v=1781742465","url":"https:\/\/partsdenmark.com\/fr\/products\/wossner-640cc-4-stroke-piston-kit","provider":"Parts Denmark","version":"1.0","type":"link"}
