Shouldn't make any difference, the computer should correct for altitude.

 

Put on 400 miles this past weekend. Total just under 1,000 total as of this morning. A little over 39 MPG calculated by me at each fill up over the weekend and 40-41 calculated by the GPS. A mixture of riding. Some at 75, some at 65, some at 25. There were 3 short times where I wanted to see what it could do and got over 100. It maxed out at 108. Over 100, it was having a tough time getting any faster.

I am a big guy, over 300 lbs, and wear a helmet with horns, so there is more wind resistance for me than some other riders.

 

38-39 no matter what. Solo @ 2500 rpm's average riding mostly in 5th.

 

First 4,000 miles.

High: 45.77
Low: 37.27
Average: 42.17

That's according to the handy dandy gas cubby app on my phone.

 

I only have 700miles logged but I'm consistently only getting 32mpg.

 

I like the picture of OPer on a bike that has a Vetter Fairing

 

After my experience riding in the Knoxville area [from Michigan] I consistently got 6-7 miles per gallon more down there than ever before. Now wouldn't you think going up and down hills on and off the gas would net worse mileage?
I have come to the conclusion that either the sea level or maybe crappier gas is why it gets worse?
That said, my new ride gets between 35/42 the old got 40/44. I got 42 this weekend riding like an old man never getting on it or going over 60. Now I know, it will be the last time it sees 42 unless it gets better with mileage.
I would like to see altitudes where this supposed 46 MPG and so on mileage occurred. Mine wouldn't get 46 in Michigan on a bet and its air cooled so less drag on the motor let alone hauling 2 and gear.

 

I only get about 33 over the highway at 80MPH.

 

well I have 67xx miles on my 14 limited and have never seen over 36 1up or 2up doesn't matter.

 

I had a 2014 Heritage before I traded up to the Limited. It got 25 to 30. I hated it.
