Engineered for enthusiasts and professionals, this kit ensures a reliable and powerful upgrade for your ride.\u003c\/p\u003e\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThis \u003cstrong\u003eWossner Standard Series Piston Kit\u003c\/strong\u003e is meticulously engineered for \u003cstrong\u003e650cc 4-stroke\u003c\/strong\u003e engines, offering a significant upgrade in both performance and longevity. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring exceptional strength and lightweight characteristics. The optimized machining process maintains critical strength in areas like the crown and skirt wall cross-section while reducing overall mass for quicker engine response. A key feature is the permanent Molybdenum Disulphite (Moly) skirt coating, which actively reduces friction and piston rock. This not only contributes to quieter engine operation but also significantly extends piston life and aids in proper break-in. Designed for a precise \u003cstrong\u003e10.0:1 compression ratio\u003c\/strong\u003e and a \u003cstrong\u003e99.95 mm piston diameter\u003c\/strong\u003e, this kit provides consistent, high-level performance. It includes everything needed for a complete piston replacement: the piston, high-quality nitride coated steel and cast rings, a wrist pin, and clips, making installation straightforward for a robust engine rebuild.\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eForged Aerospace-Grade Aluminum:\u003c\/strong\u003e Provides exceptional strength and durability, built to withstand the rigorous demands of high-performance motorcycle engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolybdenum Disulphite Skirt Coating:\u003c\/strong\u003e Reduces friction and piston rock, promoting quieter operation, extended piston lifespan, and smoother engine break-in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Lightweight Design:\u003c\/strong\u003e Precision machining ensures maximum strength in critical areas like the crown and skirt while minimizing weight for improved engine responsiveness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Piston Kit:\u003c\/strong\u003e Includes the piston, high-quality nitride-coated steel and cast rings, wrist pin, and clips for a comprehensive and hassle-free replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Performance \u0026amp; Reliability:\u003c\/strong\u003e Engineered for a precise 10.0:1 compression ratio and 99.95 mm diameter, delivering consistent power and a dependable engine rebuild for 650cc 4-stroke models.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel: Standard Series\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003eDisplacement: 650 cc\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 99.95 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size B\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 10.0:1\u003c\/li\u003e\n\u003cli\u003ePiston Material: Forged Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eSkirt Coating: Molybdenum Disulphite\u003c\/li\u003e\n\u003cli\u003eRing Material: Nitride Coated Steel, Cast\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 8575DB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381566263626,"sku":"09107055","price":265.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_ac4379b3-83c0-4191-9946-860eb233b760.webp?v=1781742497","url":"https:\/\/partsdenmark.com\/fr\/products\/wossner-standard-series-piston-kit-for-650cc-4-stroke-2","provider":"Parts Denmark","version":"1.0","type":"link"}
