Namura Piston and Rings will help to improve the performance of your KTM 85 SX 2003-2021. 

Most OEM manufacturers recommend on small-bore motocross engines need to have the piston and rings replaced every 25-30 hours to maintain peak performance and not damage the cylinder plating.

Namura uses a MOS2 (Teflon/Molybdenum) coated piston skirt which is a rolled-on process that bonds 10x stronger than sprayed on coatings. This coating offers greater heat transfer and reduces friction to help to eliminate cold seizures. The head of the piston is machined smooth to reflect combustion temperatures away from the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6% in gains.

Namura Piston & Rings comes with piston, rings, c-clips and wrist-pin.
