Wossner 8228DA Piston Kit - 1988-2004 Kawasaki KX500 Standard Size A

Wossner 8228DA Premium Forged 2-Stroke Piston Kit - Standard Size A

Reclaim the massive power of the "King of the Desert" with the Wossner 8228DA Piston Kit. Specifically engineered for the 1988-2004 Kawasaki KX500, this Standard Size A forged kit is the professional choice for maintaining Factory Quality performance in one of the most powerful 2-stroke engines ever built. At Moto-House MX, we know that the KX500 demands components that can handle immense torque and heat; Wossner’s aerospace-grade forged alloy provides the structural integrity required for this legendary 500cc power plant.

Forged from aerospace-grade aluminum alloy, the 8228DA offers superior strength and thermal stability compared to standard cast alternatives. This piston features a permanent skirt coating to minimize friction and piston rock, ensuring a quieter engine and smoother throttle response across the powerband. The dual-ring design provides an exceptional combustion seal, which is critical for maintaining the high-compression grunt that KX500 riders rely on for hill climbs, desert racing, and motocross.

Top Features: Wossner 8228DA Piston Kit

• Standard Size A (85.93mm Piston): Precision-engineered for the standard 86.00mm bore to restore original factory tolerances and compression.
• Aerospace Forged Alloy: High-strength aluminum construction designed to withstand the massive mechanical loads of a 500cc 2-stroke engine.
• Low-Friction Skirt Coating: Permanent coating reduces wear on the cylinder walls and ensures a more efficient break-in period.
• Dual-Ring Design: Optimized for maximum seal and heat dissipation, ensuring consistent power during long, high-load sessions.
• Complete Assembly: Kit includes the forged piston, high-quality rings, wrist pin, and clips.

Expert Pro-Tip: The Kawasaki KX500 is a high-performance machine that generates significant vibration and heat. When installing the 8228DA, it is essential to verify that your cylinder plating is in excellent condition. We highly recommend replacing your small-end wrist pin bearing and using a fresh top-end gasket kit. For riders in extreme conditions, ensuring your cooling system is pressurized and your jetting is precise will help maximize the life of your new forged piston.

Frequently Asked Questions

Q: Is this a Standard Size piston?
A: Yes, this is the 85.93mm piston designed for the standard 86.00mm bore. It is the ideal choice for cylinders that are within factory wear limits and have not been bored over.

Q: Why is a forged piston better for a 500cc 2-stroke?
A: Large-bore pistons like those in the KX500 experience significant thermal expansion and mechanical stress. Forged pistons are much denser than cast ones, making them more resistant to cracking and better at handling the intense pressure generated by a 500cc combustion chamber.

Q: Does this kit include the wrist pin bearing?
A: No, the kit includes the piston, rings, pin, and clips. We highly recommend purchasing a new heavy-duty small-end bearing separately for every top-end rebuild.

Recommended Pairings

• Top End Gasket Kit: Required for a professional, leak-free engine rebuild with a fresh set of gaskets.
• High-Performance 2-Stroke Oil: Keep your new forged piston protected with premium synthetic lubrication designed for high-displacement 2-stroke engines.
