Alpinestars are renowned for their off-road kit, and their motocross helmets are no exception. The Alpinestars Supertech SM-8 Radium 2 helmet offers a 3K high-density carbon outer layer for optimum strength and efficiency of energy dissipation over the shell with an Aramid fibre layer for penetration protection and uni-directional carbon composite layers for greater radial strength. This combination of layers is given even more outstanding performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the EPS liner. Each size of the SM-8 has its own individual shell size for superior aerodynamics and weight efficiency. With a fully equipped helmet testing facility facility within Alpinestars Racing Development Center, an exhaustive impact research program has resulted in the Supertech M8 returning linear and oblique impact performance, which far improves upon c
