Since I'm dreaming stuff up, I'd make it a true naked sport bike. It'd have a handlebar for ease of altering riding position, and a little something up front like the Ulisseys has, then you could simply add a piece of plexiglass for a bit of a fairing. Dual 3' headlights, and an underbelly exhaust. An "off road Hondaline silencer" would be available as well as an inexpencive "chip" for track only, of course. The solo seat version would be sprung and set up for 1 person. The dual seat version would be sprung for 2. Colors would be yellow, an almost black purple candy red.
