Namura provides high-quality piston options to suit a wide range of applications, including direct OEM replacements, high-compression variants, and multiple oversizes. B (0.01 mm) and C (0.02 mm) oversizes are also available, helping to extend the service life of expensive plated cylinders. Select applications are supported with big-bore piston kits. With the addition of MOS2 coating and hard anodising, Namura delivers improved performance and durability, without the premium price.

Features:

  • MOS2 (Teflon/Molybdenum) Coated Skirts: Applied using a rolled-on process for a bond up to 10 times stronger than typical spray coatings. Improves heat transfer, reduces friction, and helps prevent cold seizures.
  • Machined Smooth Heads: Reflect combustion heat and minimise carbon build-up, protecting the piston crown. Testing indicates potential gains of up to 6% in horsepower and fuel efficiency.
  • Anodised Domes: Enhance heat resistance and durability, with up to 75% greater strength compared to non-anodised pistons.
  • Hypereutectic Casting Process: Increases silicon content to reduce expansion, improve wear resistance, and withstand higher cylinder temperatures.
  • 0.50 mm oversize up to 100.47 mm, with a 9.2:1 standard compression ratio.
  • Includes piston (individually wrapped), OEM-quality rings (boxed separately), wrist pin, and circlips.

For a very petite wrist
I have a child-size wrist at 5.5 inches. It is hard to find watches small enough! This watch has a 6 inch fit, fitting my arm with a little wiggle room. It has spring sides for ease of putting it on, but won't allow for stretch or adjustment. Therefore, it will be tight on a standard 7 inch wrist. I am delighted with my purchase, but was hesitant to buy based on unclear size. I wanted to clarify for you the actual size to expect. I included a pic from the top and bottom of watch on my wrist, hoping to demonstrate the snug size on a tiny arm. It's a beautiful watch with unique style, and fit.
