Define a Dual-Sport?

I think this well defines what Dual-Sport is supposed to be, except for the C-4 storage compartment :rolleyes1: behind you? Runs on 7 types of fuel. Looks like a heavily modified KLR 650.

If you are interested in such a fuel tank, check out IMS tanks, this seems to be the one fitted on the bike above.
