Namura Piston NA-40007-4
Namura Piston NA-40007-4
Bore Size: 96mm
Size Over Standard: +1mm
- Includes: Piston, rings, circlips, pin
- Machined smooth piston crown (unless otherwise noted) to reflect combustion heat while reducing carbon buildup
- Hard anodized piston crown with a hardness of HRB 105
- MOS2 coating to draw heat through piston walls and out the bottom
- Minimized piston expansion and contraction
- Pistons are more resistant to wear and scuffing, expand less with heat and are stronger
- Higher Performance piston without a higher price
Why replace your cylinder when you can replace the piston for a fraction of the cost and time? Namura offers direct replacements for the original equipment as well as hi-compression and a variety of oversizes to meet your ride?s needs. They are available in 0.25mm increments, from the -1 (0.25mm) through the -8 (2mm) oversize. We also carry B (0.01mm) and C (0.02mm) oversizes which help extend the life of your expensive coated cylinders; a selection of big bore piston kits is available for some applications. Combine this with the MOS2 coating and hard anodizing, Namura gives you a higher performance piston without the higher price.
MOS2 (Teflon/Molybdenum) Coated Skirts:A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures.
Machined Smooth Heads: Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horse power and fuel economy by up to 6%
Anodized Domes: Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons
Hypereutectic Casting Process: Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures
