Had quite a few people ask me for my opinion on the new Bell Custom 500 helmets. So here goes, I got a silver flake Large size. I really didn't need another helmet but wanted a nice looking DOT open face. I first saw these online when it was posted by Stretch on the Nostalgia on Wheels blog some time ago. Was at the a local bike shop with a friend and they had one on display. Couldn't resist since I could try on for size, ordered a large right away.
Here is a size comparison to an old Bell Super Magnum that I picked up at a swap meet last year. The Bell Custom 500 fits pretty good. I usually wear a Medium that fits really tight or a Large. In this case the Bell in Large fit well.
