The best I've achieved is 74.5 mpg running highway speeds in the 70 to 75 and sometimes 80 mph speed range. I can't explain why my best mileage was on the highway. Maybe it was down hill? The worst achieved, in the low to mid 60's, was the first tank after the winter storage season, but I was out in the shed running the bikes several times throughout the winter. And talk about boxy bags! The pelicans I have mounted are among the boxiest. Try to make sure you're filling it to a consistent level to record a more accurate efficiency reading and have the dealer check your ecu to ensure accurate fuel delivery. Can't think of too much else.
