Materials quality, ease of maintenance (cleaning, etc), weight and FIT are the top reasons I spend $ on helmets. Fit is one of the biggest factors in how a helmet performs at impact.
Arai DOES make different shells, the quote above must be referring to fitting with interior changes (pad sizes, liner, etc.) not fitting all models in the Arai line.
Bottom line, without engineering info and some actual data, we are all speculating here. That being the case, I'll stick with what seems to be the best I can put on my head. Seems to me that most of the "it costs more due to fancy graphics" posts are by those who looked at two helmets and went with the cheaper one; afterall, this is a very expensive hobby. No one needs to justify their purchase either way, just go ride and good luck to you if you have to rely on your helmet.
