Full face helmet safety technology
Most of current helmet technology involves using an inner liner made of EPS foam to absorb shock. ARAI helmet manufacturer has even push the safety technology even further by designing a full face helmet shape to minimize the effect of "glancing off" impact and protect against direct impact.
However even the safest full face helmets have some technological limitations. Most of motorcycle rider head injuries are internal that are caused from sudden snapping impact although the outer physical layer of the head is free from physical injuries.
Motorcycle helmets can only protect your head from impact collisions, however it cannot fully protect your head from injuries whether it is an open face helmet, modular helmet or full face helmet. So the best practice is to ride safely in full protective gear, awareness of road conditions is the best insurance policy.
