This is the helmet i have wanted ever since i first saw it. $371.95 @ accwhse f you go to Arai's site it will cost you $514.00  plus shipping.  It is still expensive but your head is worth it.  Ill save another month to have it.  Sweet helmet.  If you want specs click here.  I love this helmet. It has a spoiler at the chin to reduce wind noise, dual intakes and exhausts, just fuking sweet......
