Tell me how a helmet should fit??

[takai]

I've always worn Bell. It pushes my cheeks in so if I move my jaw, my inside of my cheek is rubbing on my teeth, if that makes sense. You don't want it so it digs into your forehead or anything though. It feels tight but not uncomfortable.

Bell, Shoei, Simpson, Stilo and a couple of others have that fit for me. Means that if i am talking through the intercom with the helmet on i end up chewing on the inside of my cheeks and getting ulcers
Which is a pity as i really wanted a Stilo ST4 and had a really good deal on one from a mate who had the same issue.

Ended up with a Velo helmet from Andy, which has saved me money though...
