Low mileage 1100evo: 

Was getting 35 city/suburban & 38 highway.....not happy for a 400# bike

Couple of 1000 more miles am doing better but it seems to be the 100% gas...41 & still less than 40 for 10% ethanol

What did you expect...

and why?
"Once you accept that a child on the autistic spectrum experiences the world in
 a completely different way than you, you will be open to understand how that
 perspective
    is even more amazing than yours."
    To realize the value of nine  months:
    Ask a mother who gave birth to a stillborn.
"Don't piss off old people The older we get, the less 'Life in Prison' is a deterrent."

No surprise that economy improves with run in miles, or that ethanol fuels use more. Be interesting what economy is like after 5-10 thousand miles when the motor loosens up. How hard do you ride?

What do I expect.....I also ride a bike (heavier) with a larger gas tank with the same mileage, 35 mpg...

my car is more economical

I don't ride particularly hard

I am pleased with 41 mpg and am looking forward to more break-in and the smile factor is great

I can only compare to mine, but I have an S2R1000 and routinely get ~45 with hard riding mixed with slow lane splitting.

My bike has the 1100ds motor an I get low 30s in town and high 40s on the highway, have seen 50 on occasion. Of course, mine has a slippery fairing and I have a heavy hand......

Fuelly says around 40 MPG Avg....keep in mind that it is user data and all sorts of variables come into play. But it is good for a sanity check.

Weight of the vehicle effects fuel consumption during acceleration, but the primary consumer of energy at speed is drag.  Most motorcycles have a horrible coefficient of drag, especially unfaired ones, so most bikes of a similar frontal area will get roughly equal fuel mileage regardless of engine configuration or weight since most internal combustion engines have equally horrible efficiency.  (Thermodynamically maximum efficiency of a normally aspirated internal combustion engine is less than 40%)

The difference between a Dyna and a Monster is less than you think!

Fairings help slightly, but you'd be surprised how little unless the rider is properly tucked in.
Never appeal to a man's "better nature."  He may not have one.  Invoking his self-interest gives you more leverage.  R.A. Heinlein

That is my fuelly for my 09 696. I get much better mileage on the highway if i keep it to just over 70, (which is the limit here).. 75+ my mpg drops by 10%, at least..

Wow, I guess I have an anomaly. My S2R1000 routinely gets 45+. That includes lots of freeway splitting (keeping revs around 5K) a little in town riding and freeway riding above legal speeds. The Toll road I take daily has an average speed of 80+.
That road has quite a bit of elevation changes too. From about 200' to almost 1300' above sea level.
