Namura Piston Assembly - 85.5mm Bore - NA-10003-2
  • High-performance Namura pistons are engineered in the USA, manufactured in Taiwan
  • High-silicon content Hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life and reduced scuffing
  • Features machined, smooth piston crowns for reduced carbon buildup, increased horsepower and fuel economy
  • Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts
  • MOS2 (Teflon/Molybdenum) coated skirts perform at the highest standards, reducing friction and heat for added power and longevity
  • Namura rings match the OEM design except as noted
  • -B (.0004 in.) and -C (.0008 in.) fractional oversize pistons, available for some applications, extend the life of your expensive cylinder by renewing the original clearance if it's slightly worn, avoiding an expensive sleeve installation

Good Stuff
Used a couple Namura pistons in the past. Excellent piston and great price. Glad to see Dennis Kirk carries these now. Just need them to carry the gaskets as well. Recommended for all types of users.

Awsome Piston Kit
The Fit is great. I went with the .040 over boar. I'm not the overall expert on these, but I did the project with this product and now I'm riding again. The piston works great!

The machinist that did the bore really liked the product too, and he sees them everyday. That meant something to me.

Thank you Dennis Kirk and Namura!! A+
