I've worn flip up helmets for many years, including BMW's first System 1 and 3, (made by Schuberth) along with a Nolan, a newer Schuberth with the internal sun visor, and now Shoei MultiTec. I've had the mis-fortune of wrecking while in one two different times, the chin-bar remained latched like it is designed to. (Both were System helmets).
The advantages of a flip-up over a 1/2 or 3/4 helmet are obvious to anyone. Verses a full-face, they're easier for those wearing glasses and you can raise them up to talk, take a drink, etc.
Of the two I have now, Schuberth, and MultiTec, I prefer the Multi-Tec. The Multi-Tec is almost effortless in the way it opens and closes and it's single release button in the center is intuitive. The shields are quick and simple to change. I have a clear, light tint (used most of the time) and dark shield. The Schuberth is longer, probably because of it's visor behind a visor, and just feels more massive. I thought I'd like the sun visor but I don't. It only partially drops down and the contrast of looking slightly up through a dark and clear shield, then straight ahead or down through just the clear shield, is somewhat distorting for me. I hadn't heard jimmers "deep sea diver effect" description of the Schuberth before, but is accurate.
They are both good quality helmets. My advice would be to try them both on taking time to operate them a few times and go with the one that "feels" right to you. Oh, what color?

 

Yes, it does come with an accessory chin curtain, but I don't use it. It just never gets that cold out here, and as for noise, I wear earplugs. I don't get any reverb at all from under the helmet, which may be more a function of the windshield height/seat height/my height relationship than anything else. Those issues are always tricky.

In the helmet review section you can find the review for both the shoei and the schuberth.
Personally I use a schuberth J1 (3/4 with a chin guard) and I'm very happy with the overall quality and quietness.
My girlfriend has a shoei multitech and she likes it a lot but I haven't tested one myself.
One thing I like a lot about the schuberths is that they have the internal sunshade wich I find very usefull.
On the other hand the shoie has recesses for bluetooth headsets speackers wich is very usefull too (at least to me).

 

Be cool and get a retro open face from Biltwell. Yeah I know not DOT just put a sticker on it lol.

 

I got mine off uhelmets.com. Paid less than $62.00 for a modular full face. Not a fan of DOT lids,but gotta wear one on the military base I work on and I don't like to pay too much for something I don't really want. Just saying.

 

I have a brand new Black Graphite Nolan N-103 with J&M integrated Bluetooth, still in the box. (Size Large.) I purchased it thru Shawn at Dr. V-Twin, who still has it, as I am currently out of the country.

If anyone would like it for $120 less than the internet price that J&M sells it for, let me (or Shawn at Dr. V-Twin, 888-DR-V-TWIN, WWW.DRVTWIN.COM ).
