Just thought I would post regarding a recent transaction from MotoStorm. I ordered the Arioh Aviator 2.1 White in a Large size. I did a lot of research and this forum helped a great deal to determine shipment time, sizing and how MotoStorm was to order from. The large helmet fits perfect - the fit is very similar to a large in Arai. My wife wears a large in Shoei VFX and said she felt is was a little tight. I have 100% Racecraft ... I had to remove the nose piece on the googles and then they fit perfect. It was a great experience to order from MotoStorm .. I live in Ca and I ordered the helmet in the afternoon on monday and it arrived at my house on thursday ... awesome. I paid a total of 427.33 for the helmet and shipping. I got several emails from Motostorm - great communication ... helmet was shipped fedex. I would recommend ordering from this company to anyone ... awesome, fast shipping and great communication. The helmet is as everyone says ... super light, high quality and a true top of the line helmet.
