Engineered for demanding conditions, this premium forged aluminum piston kit delivers enhanced durability and optimal power output for your 4-stroke engine.\u003c\/p\u003e\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Wossner Pro Series piston kit is meticulously designed to elevate the performance and longevity of your 4-stroke engine. Crafted from high-strength forged aluminum alloy, this piston features enhanced piston pin oiling slots, radial boss machining, and annular grooves. This sophisticated lubrication system ensures superior wrist pin lubrication, significantly extending the lifespan of critical engine components under high stress. With a high compression ratio of 13.7:1, this piston is built to maximize power delivery.\u003c\/p\u003e\u003cp\u003eIts lightweight design, combined with a precise 76.95 mm piston size for a 77.00 mm bore, allows for tighter piston wall clearances, resulting in a noticeably quieter running engine and reduced vibration. The advanced skirt coating dramatically reduces friction, promotes a smoother break-in period, and enhances overall performance throughout the engine's operational life. Furthermore, a specialized ring land treatment ensures an improved ring seal and superior oil control, maintaining consistent compression and minimizing oil consumption. Where applicable, a double-bridged forging design provides exceptional structural integrity, making this Wossner Pro Series piston kit an ideal choice for riders seeking uncompromising strength and reliability. The kit includes the piston, rings, wrist pin, and pin locks for a complete installation.\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Lubrication System:\u003c\/strong\u003e Enhanced piston pin oiling slots, radial boss machining, and annular grooves provide superior wrist pin lubrication, extending component life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuiet \u0026amp; Efficient Operation:\u003c\/strong\u003e Lightweight piston design with tight wall clearances ensures a quieter running engine and reduced operational noise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Friction \u0026amp; Improved Break-in:\u003c\/strong\u003e Specially applied skirt coating minimizes friction, leading to improved break-in performance and enhanced durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Ring Seal \u0026amp; Oil Control:\u003c\/strong\u003e Advanced ring land treatment promotes a better ring seal, ensuring consistent compression and effective oil management.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExceptional Strength:\u003c\/strong\u003e Features a double-bridged forging design (where noted) for outstanding structural integrity and resistance to extreme engine pressures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit:\u003c\/strong\u003e Includes the forged aluminum piston, high-quality rings, a durable wrist pin, and secure pin locks for a comprehensive replacement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel: Pro Series\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003ePiston Material: Forged Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 13.7:1\u003c\/li\u003e\n\u003cli\u003eBore Size: 77.00 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: 76.95 mm\u003c\/li\u003e\n\u003cli\u003eStroke Length: 53.60 mm\u003c\/li\u003e\n\u003cli\u003eBore - Oversize: Standard\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eStyle: Standard Size A\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 8942DA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381494305098,"sku":"09105297","price":1519.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/fd40bdd3fe3b0f33abbbe3cd3e79b29e.webp?v=1781740685","url":"https:\/\/partsdenmark.dk\/products\/wossner-pro-series-piston-kit-for-4-stroke-engines","provider":"Parts Denmark","version":"1.0","type":"link"}
