I fill mine up @ 100 to 120 miles, and it ussually takes 2.25 to 2.5 gallons]
I am the same, I fill up between 100 to 120. I have ran out at 140 before going to reserve, but I think that was the first tank that had been ran through the bike and I have not checked again.
I am surprised to hear it has a larger tank than my bike but only goes 140 - 170 miles per tank.My wife ran dry with 178 on the TO. We were in the desert, had been doing about 65 mph. She said she was on reserve for about 28 miles. My 950 still had plenty of gas. We now carry a hose with us for those special occasions.
