I can do about 75 miles on a 250 Big Red doing pretty hard riding. I would assume the smaller displacement 185S could do a little better MPGs, but does have a smaller tank. I would plan on getting 75 miles out of a tank.
On the flip side and without ruining your original post, I am brain storming a trip to Utah on a 200S. Will you be riding near the "Paiute Trail"? After all, from what I read, it was founded by some guys on 3 wheelers back in the day.
