Engineered for 4-stroke motorcycle engines, this kit delivers superior power and reliability, making it an ideal upgrade for enthusiasts and racers.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Wossner Pro Series Piston Kit is meticulously crafted to elevate your motorcycle's engine performance. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring exceptional strength and lightweight characteristics. Optimized machining techniques maintain critical strength in areas like the crown and skirt wall cross-section, while reducing overall mass for quicker throttle response. This \u003cstrong\u003eforged piston kit\u003c\/strong\u003e features a permanent Molybdenum Disulphite (Moly) skirt coating, specifically designed to reduce friction and minimize piston rock. This not only contributes to quieter operation but also aids significantly in the engine's break-in process, extending the lifespan of your \u003cstrong\u003emotorcycle piston\u003c\/strong\u003e. With a high \u003cstrong\u003e13.5:1 compression ratio\u003c\/strong\u003e and a 90.00 mm bore size (89.94 mm piston diameter), this kit is engineered for maximum power output in \u003cstrong\u003e4-stroke engines\u003c\/strong\u003e. The comprehensive kit includes the piston, durable nitride-coated steel and cast rings, a high-quality pin, and clips, providing everything needed for a complete and reliable installation. Wossner's commitment to quality ensures a robust and high-performing upgrade for your engine's 400 cc displacement.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Forged Construction:\u003c\/strong\u003e Crafted from aerospace-grade aluminum alloy, these pistons offer exceptional strength and reduced weight, optimizing engine responsiveness and durability under extreme conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Moly Skirt Coating:\u003c\/strong\u003e Features a permanent Molybdenum Disulphite coating on the skirt, significantly reducing friction, minimizing piston rock for quieter operation, and assisting in a smoother, more efficient engine break-in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Performance Design:\u003c\/strong\u003e Precision machining ensures lightness without compromising strength in crucial areas like the piston crown and skirt wall, leading to improved power delivery and overall engine efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Compression for Power:\u003c\/strong\u003e Engineered with a 13.5:1 compression ratio, this kit is designed to maximize horsepower and torque output, providing a noticeable boost in your 4-stroke engine's performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Installation Kit:\u003c\/strong\u003e Each Wossner Pro Series Piston Kit comes complete with a high-quality piston, durable nitride-coated steel and cast rings, a precision-fit pin, and all necessary clips for a straightforward and reliable engine rebuild or upgrade.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: Pro Series\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eBore Size: 90.00 mm\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size A\u003c\/li\u003e\n\u003cli\u003eDisplacement: 400 cc\u003c\/li\u003e\n\u003cli\u003eRing Material: Nitride Coated Steel, Cast\u003c\/li\u003e\n\u003cli\u003eSkirt Coating: Molybdenum Disulphite\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 89.94 mm\u003c\/li\u003e\n\u003cli\u003ePiston Material: Forged Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 13.5:1\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 8567DA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381566230858,"sku":"09107050","price":251.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_76e0abde-3c66-4e81-85c2-ca07f4fda3a2.webp?v=1781742494","url":"https:\/\/partsdenmark.com\/fr\/products\/wossner-pro-series-piston-kit-1","provider":"Parts Denmark","version":"1.0","type":"link"}
