Governments set minimum standards for motorcycle helmets. Snell M2010 offers riders better head protection over and beyond all the protection the governments demand. Now, in North America riders have a choice to wear DOT/M2010 helmets and in Europe motorcyclists have an option to wear ECE22-05/M2010 helmets.
Impact management is a matter of just how big a hit a helmet can take before it is completely overwhelmed. For moderate hits, helmets limit the shock transmitted to the head. All standards call out what this limit ought to be. But when the helmet is overwhelmed, the shock suddenly skyrockets well beyond levels anyone might consider safe. Effectively, the head crushes the helmet wall completely and slams into the inside surface of the helmet shell. Imagine diving into a pool. A shallow dive from the edge may be no problem but diving from the three meter board requires depth. The parallel for a motorcycle crash might run all the way from a flat dive off the pool edge to cliff diving in Acapulco. It’s no wonder Snell demands all the impact management a rider might reasonably wear on his head.
Depending on helmet size, Snell M2010 helmets offer 60% to 110% more impact management capability than ECE helmets and 40% to 80% more than DOT helmets. The premium level of impact protection in M2010 helmets ensures riders better chances of walking away from hard and multiple hits in serious crashes. No one knows how much impact protection one may need during a crash, the more protection the better.
Although the M2010 advantage is its demand for superior impact management, there are several other aspects of protective performance to consider. For each of these, M2010 demands are at least comparable to, if not more stringent than, DOT and ECE 22-05.
