All this while (put about 6000 miles on RE) I have been riding with an open face (Fulmer) with Visor. I am going to get a good full face helmet (even though it doesn't match well the RE style) and even if it costs around half a grand.
There is no need to spend 1/2 Grand on a helmet. Most studies show that the high dollar helmets, ie Arai, Shoei, etc, (Snell Approved) do not offer any more protection than any other DOT approved helmet. In fact, some studies show that Snell approved helmets can actually cause more harm because they are more aimed at high speed crashes and not giving enough on low speed crashes. Snell is apparently backing off some of the limits that were on the '05 ratings as they made the helmets too hard.
I have owned them all but seem to have used the low end stuff when I really whacked my head, Nolan, AGV, which took good care of me in a couple of over the bar antics, one face plant, the Nolan, and one landing square on the head, the AGV. I have gotten off quite well just by having the helmet on. I don't think I have visibly damaged a helmet in any other get off other than a slight scratch, at most. I guess my butt weighs more than my head as that is where I usually end up sliding.
The worst head beating I ever took was with no helmet on with my head sticking out of a Bonanza door as I slid upside down down a freeway, thinking, "Where is my helmet when I really need it?!" Even a porridge pot would have saved my a few scars, however a fullface would have been nice.
At any rate a Bell Apex for a couple of hundred bucks will serve you well, if fit fits your head, as with many others in that price range. The biggest trick is to find one that fits you properly, whatever the price range. The biggest difference between the low cost and expensive stuff is the is the comfort and weight. But they are not all created equal, either. I found the Arai to be pretty heavy compared to the Shoei, the Bell fell somewhat in between. The upper level helmets tend to be put together a bit better as far as padding fit and such goes, and they generally maybe a little quieter. However, for $4 or 500 more, the difference isn't worth it. I would never buy an expensive helmet again. Besides they are a much bigger target for thieves.
At any rate, broaden your horizons, but don't totally discount the low priced spreads. They may impress you more than you think. I still have in my garage, a Shoei, Bell Apex, the one I wear if it's full face weather, Bell 500, HJC front flipping helmet, noisy and heavy, a Fulmer open face, which is the one I usually wear, with goggles, and a Davida porridge pot, my favorite, an HCI porridge pot, horrible.
My personal choice for most riding is the Fulmer as it gives my more visibility than the full face helmet, and let vanity begin here, it fits teh bike. If I were riding some other nondescript motorcycle, I'd probably be wearing the Bell Apex or maybe the Shoei. It's lighter and quieter. And quite old.
