This high-performance forged piston kit is specifically designed for Yamaha YZ450F and YZ450FX models, ensuring a precise fit and superior engine response.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eExperience unparalleled engine performance with the Wossner PRO 96.97mm piston kit. Crafted from aerospace-grade aluminum alloy using a closed-die forging process, this piston is built to withstand extreme demands, offering exceptional tensile strength and fatigue resistance. Its optimized machining ensures lightness without compromising strength in critical areas like the crown and skirt wall. A specialized dry-lute or molybdenum disulfide (Moly) surface coating on the piston skirt significantly reduces friction and prevents scuffing, facilitating a smoother break-in process and contributing to quieter operation. Each kit includes high-quality piston rings precisely designed to match the piston's thermal expansion for optimal sealing, a precision-machined steel wrist pin, and secure circlips to ensure reliable component retention. This Wossner piston kit provides a complete solution for rebuilding or upgrading your Yamaha YZ450F (2018-2019) or YZ450FX (2019-2020) engine, promising improved performance and long-lasting durability.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Forged Construction:\u003c\/strong\u003e Made from premium aerospace-grade aluminum alloy with a closed-die forging process, aligning grain structure for maximum tensile strength and fatigue resistance, ensuring exceptional durability under race conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Skirt Coating:\u003c\/strong\u003e Features a permanent dry-lute or molybdenum disulfide (Moly) coating on the piston skirts, actively reducing friction, preventing scuffing, and promoting a smoother, quieter engine operation and an easier break-in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Lightweight Design:\u003c\/strong\u003e Precision machining shaves off unnecessary weight while maintaining critical strength in areas like the piston crown and skirt wall cross-section, contributing to improved throttle response and overall performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit for Easy Installation:\u003c\/strong\u003e Each Wossner 96.97mm piston kit comes complete with the forged piston, high-quality piston rings, a robust wrist pin, and secure circlips, providing all necessary components for a comprehensive rebuild.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngineered for Yamaha YZ Performance:\u003c\/strong\u003e Specifically designed to meet the rigorous demands of Yamaha YZ450F (2018-2019) and YZ450FX (2019-2020) engines, guaranteeing precise fitment and optimized power delivery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Wossner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Type:\u003c\/strong\u003e Forged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size:\u003c\/strong\u003e 96.97mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Skirt Coating:\u003c\/strong\u003e Molybdenum Disulfide (Moly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Includes:\u003c\/strong\u003e Piston, Piston Rings, Wrist Pin, Circlips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e Yamaha YZ450F (2018-2019), Yamaha YZ450FX (2019-2020)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 09107129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":63699742851402,"sku":"09107129","price":2835.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/6bfa08f00e41d1542593858f849be5b8_3080ddfc-8bb6-4abf-b1b9-ae9e1bc93749.webp?v=1790463327","url":"https:\/\/partsdenmark.se\/products\/wossner-pro-piston-kit-96-97mm-for-yamaha-yz450f-yz450fx","provider":"Parts Denmark","version":"1.0","type":"link"}
