Good review I’d agree with what Kayak23 says in his review.
The Xar wouldn’t fit me comfortably, so have was looking for a replacement for my Xen for far to long, as the Feature simply doesn’t have enough vents for me. Tried the Bell on and it cupped my head so well that it felt like the Xen (of which I’ve had 2 over 8/9 years) had been sitting on my head rather than cupping it. The venting works well but again due to shape it does cover more of my head than the Xen, and so I’d suggest it does have to work harder.
Minor niggles are the visor bolts which are a little pathetic & seemingly the distributer isn’t even gunna try (admittedly I haven’t bothered chasing for one), but hardly a reason to put you off the helmet completely.
Can’t report on the longevity of the speed dial system, I know a concern on your Xar, but had mine just under two months and no issues to report. Seemingly a bunch of ‘AM’ type helmets appeared after this one (TLD and IXS for a start), I don’t regret buying the Super over those
Loving my badger look.. couldn’t live with a white one and the green really is lurid!
PS: on the large bonse front, the largest Urge-o-matic wouldn’t even fit on my head, the Super fits fine.
