Alpinestars Supertech M8 Radium 2 Adult Off-Road Helmets
The S-M8’s design is coherent to Alpinestars philosophy and shares distinctive themes with other products in the portfolio; a smooth, attractive, profile which is streamlined and free of any external channels and features that might act as a load point in an impact, or compromise the overall integrity of the construction. The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider’s head from direct force to the skull and referred to the neck and spinal column. The aperture is designed to accommodate a wide variety of goggles and the air vents in the shell are located to maximize ventilation efficiency.
- The helmet’s shell construction utilizes a highly advanced molding technology with a multi-composite combination:
- 3K Carbon, high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell
- Uni-directional carbon composite layer that gives significantly greater radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy
- Aramid fiber layer which provides critical penetration protection
