Hey i'm a new rider, i'm taking the motorcycle safety course this weekend. I wanted to get peoples opinion on helmets for people who ride cruisers. I'm going to probably get a small bike starting out like a 650 s40 hopefully find one thats bobbed out. How come it seems that just sport bike riders wear full face helmets? I was thinking about buying a 3/4 helmet. Would a 3/4 helmet work out good for cruising? or does it not really matter?
