I just received an Arai Classic C helmet with the J & M headset installed. I like the helmet, but then I dont like it. And Im not sure why. I 99% of the time have been wearing a half helmet, but wanted a 3/4 helmet also. I dont know if its the snug fit of the Arai, or what. But I have ordered the KBC Tourcomm helmet also to compare it with the Arai, and will send back the one I dont want. I know the Arai is the cadillac of helmets, so that is the one I will probably keep. But I was hoping others have tried out both, or just one or the other, and would give me some feedback on what you like and dont like about them. Thanks.
