Hey guys. I'm looking into getting an Arai helmet. I'm not a helmet expert, so I'm not really sure what to look for in getting a helmet. So I'm wondering, due to the varying prices of the Arai models, is one better then the other? Is there a big difference in protection? ex. If I get the most expensive one, I'm better protected then the one that's $300 cheaper? I know that when looking for a helmet, It's not just protection, but comfort. Am I looking at the right helmets here? Or should I be considering another brand. I've heard in several places now that Arai are the best. Now I just have to find them for sale somewhere nearby, so I can try them on and determine the correct size for me. Thanks for the help.
