Tell us what speeds you were going. Percentage of city and highway riding. Octane rating fuel. Did the fuel contain ethanol? I'll start this off with my first tank. After I left the dealer with mine, I topped it off with 87 octane non ethanol and went 205 miles when the fuel gauge started flashing. I rode 17.4 miles more and topped off with again with 87 octane non ethanol, 3.1206 gallons. I rode the speed limits from 55 - 70 mph 95% highway 5% city. I usually shift between 2600-3500 RPM. On this tank I wasn't trying for the best I could get, I was just riding like I normally do when going to and from work. 222.4 / 3.1206 = 71.26 MPG. I know some have beat this mileage, but lets see who can get the best on ADV. Then maybe we can see who can get the worst.
