I'd just make a comment on ordering on-line. I never do it as there is no guerentee of a fit unless you can get a try of a buddies, and a good snug fit that doesnt squeeze the life out of you is very important. Heads and helmets come in different shapes as well as sizes.

Me? I'd take a weekend break in Dubia and check out the shops there. Al Yusssf (Yamaha) have Nolan. Mid range helmets, I heard the Aprilia dealers have Arai. But if you're going, drop me a line and I'll check with my bro's over there. I ride a Harley (nearly 30 years on two wheels - done the sports bike to death though I like the new Kwak) but I don't wear thier helmets. Way overpriced for the quality. If I travel I always check out the bike shops. I bought a Shark from the UK and a bell open face from the states ($90 - riding is a little safer there). I bought a Nolan in the UAE and I'm very happy with it.
