Wossner K4048DA-3 Piston Kit - 2016-2025 Yamaha YXZ1000R 4-Stroke Forged

Wossner K4048DA-3 Pro Series Forged 4-Stroke Piston Kit

Push the limits of your Yamaha YXZ1000R with the Wossner K4048DA-3 Piston Kit. Specifically engineered for the 2016-2025 Yamaha YXZ1000R, this Pro Series kit is designed to provide professional-grade durability and performance. At Moto-House MX, we understand that UTV engines face extreme loads and high sustained RPMs, which is why we offer Wossner’s precision-forged components to ensure your triple-cylinder powerhouse remains reliable and fast.

Forged from high-silicon aerospace-grade aluminum alloy, this piston features Wossner's signature double-bridged forging for maximum structural integrity. The design includes enhanced piston pin oiling slots, radial boss machining, and annular grooves to ensure superior wrist pin lubrication during aggressive driving. With a 13.0:1 compression ratio, this kit maintains optimal combustion efficiency while the skirt coating reduces internal friction for a quieter, cooler-running engine and a faster break-in period.
