The difficulty with Arai is that they are pricing themselves out of the market a bit. Look at the RX7-GP's, pretty much £700 (although it's possible to get them cheaper online) Expense aside though, I've only ever used Arai, tried other makes on, but prefer the feel and fit of an Arai
very quiet mate , they are more a Arai shape than Shoei if you have an Arai shaped head you will love them
