I know they make combonation dirtbike/streetbikes. They arn't the best thing on and off road, but they work and they are street legal. Personally I would see if I could change it to a diesel motor, get 200 mpg, and carry a 5 gallons of diesel on the sides with those side saddle gas carriers and a bag with my gear on my back. Figure 8 gallons of diesel or so would get me 1,600 miles. But, I haven't seen anything like that yet. <img src="/images/graemlins/frown.gif" alt="" />
