Mounting a GoPro on the CB1100. Some ideas.

[Elipten_imp]

Not to be mean but it seems obvious attaching anything but especially something that protrudes and changes the form of the helmet compromises the design of the helmet. When the impact occurs on the attached device it would greatly affect the distribution of the received forces to to helmet shell and interior and no doubt concentrating the force to a small area versus spreading the force on the shell. Since the helmet designer has no way to know how, where or what was attached to the helmet; there can no way to model the forces to compensate.

Seems rather intuitive if you think about it for a moment
