Wossner 8098DB Piston Kit - 2004-2008 Suzuki RM125 2-Stroke Size B

Wossner 8098DB Premium Forged 2-Stroke Piston Kit - Size B

Keep your Suzuki RM125 screaming at the front of the pack with the Wossner 8098DB Piston Kit. Specifically engineered for 2004-2008 Suzuki RM125 cylinders that require a Size B fitment, this kit is designed to restore Factory Quality power and the razor-sharp throttle response that made the RM a legend on the motocross track. At Moto-House MX, we provide the precision-forged components required to maintain peak compression and high-RPM reliability in used cylinders.

Forged from aerospace-grade aluminum alloy, this piston offers a superior strength-to-weight ratio compared to standard cast pistons. This is critical for 125cc engines that live at the top of the RPM range. The permanent skirt coating significantly reduces friction and piston rock, resulting in a quieter engine and improved mechanical longevity. This Size B piston (53.96mm) is designed for cylinders with a 54.01mm bore, providing the precise clearances needed for optimal performance in seasoned cylinders.

Top Features: Wossner 8098DB Piston Kit

• Standard Size B (53.96mm): Precision-engineered for 54.01mm bores to maintain perfect tolerances in cylinders with standard wear.
• Aerospace Forged Alloy: Premium aluminum construction for maximum durability and thermal stability during intense motos.
• Low-Friction Skirt Coating: Permanent coating reduces internal wear and mechanical noise for a more efficient engine.
• Single-Ring Racing Design: Optimized for reduced drag and high-RPM efficiency, maximizing the RM125’s peak horsepower.
• Precision Lightweight Machining: Maintains structural strength while reducing reciprocating mass for faster acceleration.
• Complete Assembly: Kit includes the forged piston, high-performance ring, wrist pin, and clips.

Expert Pro-Tip: The 2004-2008 RM125 engine thrives on tight tolerances. Size B is the ideal choice for a cylinder that has been through several top-end refreshes, as it compensates for the microscopic wear of the cylinder plating. Always use a new top-end gasket kit and inspect your exhaust power valves for carbon buildup to ensure the engine hits the pipe cleanly.

Frequently Asked Questions

Q: What is the difference between Size A and Size B?
A: Size B (53.96mm) is exactly 0.01mm larger than Size A. This slight increase allows you to maintain the factory-specified piston-to-wall clearance as the cylinder wall experiences natural wear over time.

Q: Does this kit include the wrist pin bearing?
A: No, the kit includes the piston, ring, pin, and clips. We highly recommend purchasing a new small-end bearing separately whenever you perform a top-end refresh.

Q: Will this fit older RM125 models?
A: No, this specific kit is engineered for the 2004-2008 engine platform. Older Suzuki RM125 models utilize different piston specifications.
