Dual tanks...both under the tank in line with the seat or ???
Looking at the photo Ossi posted, I am thinking of the Husky / BMW model, not the X.
Yes dual tanks, the main tank under the seat, a smaller tank (looks like a radiator overflow tank) housing the pump underneath.

I believe it's the gray colored box behind the head in this photo, if I am understanding correctly what I have read about the bike.
