Superior shock absorption performance is the most important requirement for a solid helmet to protect your head.In fact, Aras long history is also the tracks of their hard work that has been increasing. Meanwhile, motorcycle riders are also fact that they run faster than standard test collisions.Since kinetic energy increases proportionately to the squares of speed, riders who wear helmets have huge energy as well as on the race track, on public roads.When you receive it, any helmet will exceed the limits of its capacity. But there is still a way to deal with big energy.When hitting an obstacle, it will disperse the energy of the impact and be dramatically smaller as the helmet has to absorb.Therefore, in real-life situations, the performance of de-impact performance is also an important factor of shock absorbing performance. In the case of an emergency, Arai learned in a long history that round, smooth, and strong hat is more effective for the "throwing impact" performance.Alai never forgotten this fact that no matter what the public standards are and can protect yourself with a motorcycle rider. The impact can be rejected as much as possible.And if you didnt cut it out, you will "absorb" it.Arai is the basics of a helmet to protect your head. Therefore, all models of Arai are considered "shock deflecting performance" and have a continuous form of round smooth spheres above 75R (continuous convex surfaces with a curvature radius of 3.0 inches (75 mm) or more), and the strong shell.This is an important commitment advocated by Arai.
