I just got back from a week tour down to San Francisco, four days into which I replaced my old KBC VR-1 with an Arai Profile. I have lost weight recently, and combined with the wearing of the KBC's liner it was way too loose and needed to be replaced. Besides, it was five years old and due for replacement anyway.
Now I know even KBC's helmets have surely been improved in the last five years, but the difference with the Arai was night and day. It is so much lighter that it barely feels like I'm wearing a helmet. And the venting actually works! I can feel air moving over my scalp -- trust me, that helped in the 100 degree heat in the central valley of NorCal. It also doesn't get buffeted around as much in the wind.
And perhaps best of all, the padding is actually designed to allow you to wear glasses. I was only able to wear my sunglasses for a few hours at a time in my KBC, because the pads pressed the temples into my skull, giving me a wicked headache. (It was also tough to find sunglasses that I could force into the helmet without getting bent to sh*t.) The first time I slipped them into the Arai I was stunned. It was like I wasn't even wearing the lid.
I suppose I could have shopped around and found a cheaper helmet with similar features, but I had done some research and found the Profile is designed for my head shape so I decided to suck it up and spend the cash. Besides, I saved some $$ buying it in the states, anyway.
Now if only I can figure out how to get the damn shield back in without f*cking with it for half an hour!
