Well, that is a thought, but I'm thinking that would make me uncomfortable.
A) seems a bit of weight high up, and way out on the end, of a scooter's center of gravity
B) maybe stopping for gas every 75 miles might give the keester a welcome break
C) might it be better to keep a large fuel can in the garage & fuel the scoot before each ride?
D) is it an actual 'tank' for safely transporting gas - or a plastic gas can?
