Engineered for the demands of high-performance motorcycles, this \u003cstrong\u003eforged piston kit\u003c\/strong\u003e delivers exceptional strength and reduced friction, ensuring a quieter and more efficient power delivery.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Wossner Pro Series Piston Kit is meticulously designed to optimize the heart of your 250cc 4-stroke engine. Forged from aerospace-grade aluminum alloy, this piston ensures superior resilience against the extreme pressures and temperatures of high-performance riding. Its impressive 13.5:1 compression ratio is engineered to unlock maximum power and responsiveness from your engine, providing a noticeable boost in acceleration and overall output.\u003c\/p\u003e\n\u003cp\u003eEach piston features an advanced Molybdenum Disulphite (Moly) skirt coating. This permanent, high-quality coating significantly reduces friction between the piston and cylinder wall, minimizing wear and tear while promoting a quieter operation and aiding in a smoother break-in process. Optimized machining techniques contribute to a lighter piston without compromising strength in critical areas like the crown and skirt wall cross-section, ensuring both durability and agile engine response. This comprehensive \u003cstrong\u003emotorcycle piston replacement\u003c\/strong\u003e kit includes everything you need for installation: the piston itself, high-quality nitride coated steel and cast rings, a piston pin, and retaining clips, making it a complete solution for your engine rebuild or upgrade.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Forged Construction:\u003c\/strong\u003e Manufactured from premium aluminum alloy, ensuring exceptional strength, durability, and resilience under extreme engine conditions for long-lasting performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Molybdenum Disulphite Skirt Coating:\u003c\/strong\u003e Features a permanent Moly coating that drastically reduces friction and piston rock, leading to quieter operation, improved longevity, and a smoother engine break-in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Lightness \u0026amp; Strength:\u003c\/strong\u003e Precision machining reduces overall piston weight while maintaining critical strength in the crown and skirt areas, contributing to faster engine response and enhanced reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Compression Ratio (13.5:1):\u003c\/strong\u003e Engineered with a 13.5:1 compression ratio to maximize horsepower and torque output, delivering a significant performance advantage for your 250cc 4-stroke engine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit for Easy Installation:\u003c\/strong\u003e Supplied as a comprehensive kit including the piston, high-quality rings (nitride coated steel and cast), piston pin, and clips, providing all necessary components for a straightforward rebuild.\u003c\/li\u003e\n\u003c\/ul\u003e\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: 250 cc\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 13.5:1\u003c\/li\u003e\n\u003cli\u003eBore Size: 77.01 mm\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 76.97 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size B\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\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381568459082,"sku":"09107071","price":1619.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_7e829cbd-feda-4cdb-971d-ea759966d0b7.webp?v=1781742618","url":"https:\/\/partsdenmark.dk\/products\/wossner-pro-series-piston-kit-for-250cc-4-stroke-13-5-1","provider":"Parts Denmark","version":"1.0","type":"link"}
