^^ what he said. if you really want a modular, get a good one (arai, shoei, etc) . avoid the Scorpion 900 one, that helmets chin bar is one of the flimsiest things ive ever seen. its actually designed to pop off so you can wear it as a 3/4 helmet. (why on earth would you want a chinbar thats designed to break off?)
i want to buy a modular helmet because i wear glasses and regular full-face helmets are a bit of a pain to take on and off with glasses on, but i've considered buying the Bell Revolver Evo, i like my current Bell Helmet, but im not sure if the ease of putting it on/off is worth the risk.
