FYI, I have a brand new, size large SR1 Technology in the matte black finish that I'm about to return for fit reasons. Ordered it out of Europe since I wanted a lighter ECE version (the DOT ones are a couple hundred grams heavier), but it didn't take more than a few minutes on my head to know it wasn't going to work for me - gives me a headache from too much pressure on my forehead. Size is right (I'm 58cm), it's just not the right shape for my bean, unfortunately. I am on the long-oval side, almost an Arai Profile shape; the original Arai Vector worked well for me. The SR1 internal shape seems similar to a Shoei RF1100 to me; bit tight front to back with some room on the sides.
Brief impressions from handling it and wearing it for 5-10 minutes indoors mirror most of the above; very light, with a definite race fit. Very snug neck roll (which will help a lot with wind noise from the bottom, which my Bell Star suffers from horribly), but fine once on. Comes down around your face lower than some with a larger chin bar, which should also help with noise. Haven't really messed with the vents or even taken the plastic cover off the faceshield, so I have no idea of how well they work on the road, but it's a really nice bit of kit - wish it fit me!
So; if anyone in the US wants a shot at it before I send it back, PM me. With shipping, exchange fees and customs duties I've got $760 in it, which is what it would take to get one like it into the US. $660 shipped in ConUS if you're interested; DOT versions are $969 online currently.
