Did the dealer actually tell you that the helmet was made by HJC? I felt like I was treated like an idiot for asking if HJC and/or Bell made a pair of helmets I was looking at at two different dealers. In the first case, I had already seen the bell label inside the helmet padding. The second case was probably the helmet that you bought if it looks just like HJC's IS Max II.
I didn't argue with either of these people and wasn't sure if they were just uninformed or if they were told to lie about this stuff.
