This is, I believe, because my engine is not warming up enough in the sub freezing ambient air temps and the bike is continually running rich. I've noticed that my engine temp gauge has rarely gotten above 3 bars this winter but as soon as it hits 4 bars my gas mileage goes up.
I've seen the same on the R1200GSA and F800GS. Right now doing 49mpg commuting while in the summer month I've seen about 56-57mpg average.

No, he did reset the computer when coasting into your driveway

I hate this thread, it always depresses me. Granted, I almost always ride with the damn bags on, and always with the TT windscreen but still . . . I don't think I've ever seen over 45 mpg. I don't think my bike would ever get more than 200 miles on a tank.

Maybe I should try actuall paying attention to it though and see what it really is.

No bags, but a screen on a 658 and I get ~ 48-55 depending, so 200 miles would be running the tank to empty.

That doesn't sound right. Even with bags and a screen. On the 16T with bags and a big screen I can get high 50s on 55 mph roads in weather above 60 degrees. I follow though by saying, that the beast loses mpgs considerably at speeds faster than 70 and in cooler temps when idling.

Yeah, I should have said this is at California freeway speeds of 75-80 mph.

I'm not sure about other locations but in winter in Colorado we see lots more ethanol in the gas and different mixtures which definitely affect gas mileage; but then and again we don't ride quite as much in winter either - snowing hard right now and the temps are dropping.

city mileage : 44 - 45 mpg
touring : 52 - 53 mpg. There have been days that I've made an average of 66 mpg though, but the 53 mpg is what I get more often.
highway (>150 kph) : 39 - 40 mpg

800gs
Last weekend, ran 124 miles 70-80mph temp around 50-55 & used 3.65Gal (reserve light was on)
Later in day ran 92 miles 70-80mph temp in 65-75 & used 2gal
Best ever , mostly downhill running 15-25mph & (neutral) temp 70+ got 67 for a gal.

Mileage is all over the place, I try to find fuel stops every 100 miles.
