i average 45.7 in warmer temps with speeds around 70-80...i weigh 235..it starts to drop with colder temps..does it every year.

 

2018 1200 Iron (stock)
52 mpg
math it at fillups

 

39-42MPG 2010 Forty Eight with tuner, exhaust, and intake. I'm 245# and ride it very spirited.

 

2003 XLH 883 Hugger....48-61 mpg (speed makes the difference, I usually get around 52)....gutted OEM exhaust, UNI foam filter, stage one carb....I do the math at fill up.

 

On my 2006 12000C, Stage 1, I got anywhere from 35-55 MPG depending on how I was riding. I calculate my mileage by dividing miles ridden by fuel used.

 

2017 883 SuperLow. SE air cleaner, crankcase vented out of the airbox, Cobra Power Pro RPT 2-1 exhaust, reflashed and auto tuned with an FP3, and I ride the bike more like a sport bike than a cruiser.

Running on summer blended fuel I see mid/upper 50's mpg, on winter blended fuel that drops to low/mid 50's mpg. All that on premium 91-93 octane pump gas, never have seen any benefit from, or worth the cost/time with finding ethanol free gas.
