4 1/2 gallons where? maybe 3 or 2.5
The little wings on the tank appear to be just wings.
I see something that looks like an inlet tract going to an airbox under the seat.
Gotta have a battery, likely under the seat.
Not much fuel there with the other stuff in the way.
It just looks like a mx bike with a rally fairing and low fender.
Must be for those small euro deserts?
