I put in a nice little 105 mile tour of the area today. Spent most of it on the dirt roads around here. I would like to see if there is any way to get to Coulee dam on the back dirt roads. They aren't real exciting but better than tarmac! I wanted to hear from others about their top speeds. In the dirt, wide open throttle, I can get 75mph, thats it. Not real terrific compared to my 5 hundy, but good enough. I tried to gps all of it, but lost reception when I put the unit in my pocket. Lots of roads out here!
