I dont understand the deal w/ quarter or half shells either to be honest...most sportbikers wear full face, for obvious reasons..but the quarter & half shells will protect the top of your head, but hell, what about the rest :shock: I mean, if you go down, the top of your head is nice n safe, but your face, the sides and back of your head are all mangled up..I just dont understand. I know b/4 the PA helmet law was lifted, it was a rebel act for alot of riders, wearing only the bare minimum to be legal, but now that its lifted, they still wear them alot of the time..why bother..but thats just me.
