Title: GAS MILEAGE
Post by: jmdaia on July 14, 2015, 06:20:00 PM
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?

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.

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.
