Namura Performance Piston & Rings 1981-2023 Yamaha PW50.

Most OEM manufacturers recommend that small-bore motocross engines have the piston and rings replaced every 25-30 hours. This is crucial to maintain peak performance and avoid damaging the cylinder plating. One brand that offers reliable and high-quality piston kits is Namura.

Namura utilizes an advanced MOS2 (Teflon/Molybdenum) coated piston skirt. Unlike sprayed-on coatings, this unique rolled-on process creates a bond that is ten times stronger. The coating not only facilitates better heat transfer but also reduces friction, effectively preventing cold seizures.

In addition to the coated piston skirt, Namura pays attention to the design of the piston head. It is carefully machined to have a smooth surface that reflects combustion temperatures away from the piston. Studies have shown that this feature can yield impressive benefits, such as a potential increase in horsepower and fuel economy by up to 6%.

When you choose a Namura piston kit, you can expect a comprehensive package that includes not only the piston itself but also rings, c-clips, and a wrist-pin. This ensures that you have all the necessary components to complete the replacement process.

Features:

  • Namura piston kits come with the piston, rings, and wrist pin, Wrist Pin 
  • OEM quality rings packed in their box, a wrist pin, and circlips.
  • MOS2 (Teflon/Molybdenum) Coated Piston Skirts
