Namura piston KTM SX/EXC 250 2003-2025
Namura piston for KTM SX/EXC 250 models from 2003 to 2025 is designed for high-performance 2-stroke engines, delivering excellent wear resistance and thermal stability. Ideal for engine rebuilds and maintenance in demanding motocross and enduro applications.
Manufactured from hypereutectic aluminum alloy, this piston minimizes thermal expansion and improves durability. The MOS2 (Teflon/Molybdenum) coating reduces friction and enhances heat dissipation, while the anodized dome and precision-machined head optimize heat reflection from the combustion chamber and reduce carbon buildup.
Technical Features:
- Compatible with KTM SX 250 / EXC 250 2003-2025
- Hypereutectic aluminum alloy construction
- MOS2 coating for reduced friction
- Anodized dome for enhanced thermal resistance
- Machined head for improved combustion chamber heat management
- 2-stroke engine with single ring design
- Available in oversizes from 0.25 mm up to 2.00 mm (-1 to -8)
- Available in B (+0.01 mm) and C (+0.02 mm) sizes
- Includes Rings, Piston Pin and Clips / Circlips
Benefits:
- Improved durability and wear resistance
- Better heat dissipation and reduced seizure risk
