1995 Harley Davidson Electraglide Ultra...Last tank 51 mpg mostly 2 up, secondary roads. Leisurely ride last Sunday 45 to 60 mph. I have been using 93 octane non ethanol from a mom and pops country store near my house. The non ethanol 93 seems to be getting about 4 to 5 more mpg than the 89 octane ethanol swill I had been using. 148 miles took 2.8 gallons to top it off.
