This high-performance piston kit delivers superior strength, reduced friction, and optimized power output, making it an essential upgrade for serious riders and racers.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\nThe Wossner Pro Series 125cc 4-stroke piston kit is meticulously crafted to meet the demanding requirements of modern motorcycle engines. Forged from aerospace-grade aluminum alloy, this piston ensures exceptional strength and longevity, even under extreme operating conditions. Its optimized machining process focuses on achieving the lightest possible weight without compromising structural integrity in critical areas like the piston crown and skirt wall cross-section. A key feature is the permanent Molybdenum Disulphite (Moly) skirt coating, which significantly reduces friction between the piston and cylinder wall. This not only promotes quieter operation and extends engine life but also assists in the critical break-in period, ensuring a smooth start to your engine's enhanced performance. Designed for a 54.00 mm bore and delivering an 11.0:1 compression ratio, this Wossner piston kit provides the ideal balance of power and reliability for your 125cc engine. Each kit includes the precision-engineered piston, high-quality nitride coated steel and cast rings, a durable piston pin, and secure clips, providing a complete solution for your engine rebuild or upgrade.\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnrivaled Durability:\u003c\/strong\u003e Forged from premium aerospace-grade aluminum alloy, this piston kit offers exceptional strength and resilience, designed to withstand the rigors of high-performance 125cc 4-stroke engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Performance \u0026amp; Efficiency:\u003c\/strong\u003e Features a permanent Molybdenum Disulphite (Moly) skirt coating that drastically reduces friction, leading to quieter operation, improved fuel efficiency, and extended engine life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Engineered Lightness:\u003c\/strong\u003e Expertly machined for optimal lightness while maintaining robust strength in crucial areas such as the piston crown and skirt wall, ensuring responsive power delivery without sacrificing reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Break-in Protection:\u003c\/strong\u003e The advanced Moly coating not only reduces friction during operation but also actively assists in the critical engine break-in process, promoting smoother initial performance and longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit for Easy Installation:\u003c\/strong\u003e Each Wossner Pro Series Piston Kit comes complete with the high-quality piston, precision-matched rings (Nitride Coated, Steel, Cast), a sturdy piston pin, and reliable clips, providing everything needed for a comprehensive piston replacement.\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\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003eDisplacement: 125 cc\u003c\/li\u003e\n\u003cli\u003eBore Size: 54.00 mm\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 53.94 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size A\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 11.0:1\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 (includes piston, rings, pin, clips)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381568721226,"sku":"09107076","price":181.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_195d5908-97ee-43f2-8e24-b16db7b23f16.webp?v=1781742640","url":"https:\/\/partsdenmark.com\/fr\/products\/wossner-pro-series-piston-kit-for-125cc-4-stroke-engines","provider":"Parts Denmark","version":"1.0","type":"link"}
