I have Arai Viper GT road helmet and Airoh Stealth Senior mx helmet. Both are M size and both fits perfect to my head.
Man I think you just found my new helmet for me. I really like the look of the bottom pic of the 2011 Airoh Aviator.
Since I will have to order one on line, I wont be able to try one on. I would like it to fit right the first try with out the hassle of a return. You guys that own the Airoh is the sizing comparable to a Arai?
Thanks,
Roscoe
