I happen to be looking at old news on Moto GP's website and happen to come across something on Arai helmets.

If you watch the the first 10 seconds of this video you will see a bunch of Arai helmets on a rack. The one Shinichi Suzuhara picks up is Dani Pedrosa's helmet. If you look at the one right next to it on the right side, look at the front chin vent. It looks like 6 holes instead of the flip vent that opens up on normal Arai helmets. Another thing is he points out that theres 6 vents on the top of the helmet as where on a normal one theres only 4. Then if you look out for it you can see a clear piece kind of like a lip spoiler connecting to both of the top vents near the back part of them. Last thing is the rear vents on the bottom that are right behind your ears. They have covers over them and a normal one is just holes going right into the helmet.
Is this a new version of the Arai RX7 thats not out yet or is this something custom that only Moto GP riders have access to?
