Comparing the new 317 with the original type 3, the lower fenderskirt is 18 inches wide versus 14 inches, so 4 inches wider, and at the handlebar bulges, 22 versus 20, so 2 inches wider. But the bulges, or nacelles, are much sharper, distinct & well defined. IDK what happened with the original ( I suspect certain persons may have touched the fiberglass, ran their hands over it, before it hardened, but I fell asleep, so I didn't see them do it).
