Wossner Pro Series Forged Piston Kit - Size B - 8949DB

Elevate your ride's performance and durability with the Wossner PRO 96.97mm piston kit, engineered for peak power and reliability. This high-performance forged piston kit is specifically designed for Yamaha YZ450F and YZ450FX models, ensuring a precise fit and superior engine response.

Description

Experience 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.

Features & Highlights

• Aerospace-Grade Forged Construction: 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.
• Advanced Skirt Coating: 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.
• Optimized Lightweight Design: 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.
• Complete Kit for Easy Installation: 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.
