WOSSNER 8088DB 2002-2004 Kawasaki KX250 66.35mm Forged 2-Stroke Piston Kit

Give your KX250 the precision of a forged Wossner piston and head to the starting gate with the confidence that your top end is built for peak performance.

Restoring the power of your 2-stroke engine requires components that can handle the heat of competition. This Wossner Forged Piston Kit is the professional’s choice for the 2002-2004 Kawasaki KX250, offering a significant upgrade in durability over standard cast pistons. Forged from aerospace-grade aluminum alloy, this kit provides the structural integrity needed to maintain high compression and crisp throttle response, ensuring your bike performs like it just rolled off the factory floor.

Engineered for the serious racer, Wossner pistons feature a permanent skirt coating that minimizes friction and reduces piston rock. This results in a quieter, smoother engine cycle and extended life for both the piston and the cylinder wall. Each kit is precision-machined to balance lightness with reinforced strength in the crown and skirt areas. When you choose Wossner, you are investing in Factory Quality reliability that allows you to focus on your lines, not your maintenance intervals.

• Aerospace Forged Alloy: Provides superior strength and heat resistance for high-RPM 2-stroke racing.
• Permanent Skirt Coating: Reduces internal friction and wear for improved performance and longevity.
• High-Performance Dual Rings: Ensures a superior seal and efficient heat transfer from the piston to the cylinder.
• Precision Machining: Optimized for weight reduction while maintaining critical strength in high-stress areas.
• Complete Top-End Kit: Includes the 8088DB piston, high-quality rings, wrist pin, and clips for a seamless rebuild.

Expert Pro-Tip: To ensure maximum longevity, always measure your cylinder bore to confirm that a "Size B" (66.35mm) piston provides the ideal clearance. During assembly, apply a light coat of high-quality 2-stroke oil to the rings and wrist pin, and always use a fresh top-end needle bearing for a professional-grade finish.
