Dunno about you guys in the states, but in the antipodes a chain guard is a legal requirement on a motorcycle. I had it out with a cop a while back when he was giving my scooter a look over. I'd ditched the belt guard and he was gonna defect it. I pointed out that it's a belt, not a chain and the Rules say a CHAIN has to be covered, says nothing about a belt. I got away with that one.
. Not so the missing front fender or obscured number plate... :'(
That one, does look like it was hacked for tyre clearance.
