I might look like a troll but that figure is genuine. My best top speed per the GPS is 75 - 79mph on the level, both ways. These things can MOVE! Plus I can out-dabble a Harley from the light. Remember it is a 300cc lightweight vehicle.
I even kept up with a Yamaha doing 70 all the way to Asheville, NC. There was a 15 mph headwind the whole way. Cut the fuel consumption down from 63 to close to 50!
