So, you got 56, I haven't seen any other bikes getting any better at those speeds. It will go lower, I saw someone record 52. That still seems pretty good for the low side of mileage figures.
well, how much did you put in to fill it up? I only get 2.5 gallons in when I fill up. 140/2.5 sounds about right. Naaim recorded 57 for his first two tanks, and was doing some 'tests.' My lowest so far is 62, but it wasn't all highway and mostly only 60-70
