Yes but how long are you typically riding for?

My journeys are very short and the engine is barely able to get up to it's more fuel efficient temperature.

12 mile commute each way on country roads and a bit of 30mph limits.
Just a side note, I broke my engine in the harsh way and not the manual recommended way.

Indeed, that's what I've always done with my bikes, and I got only 61mpg on my first tank with the 500X (gentle riding).   :003:

If you are using fuelly, then the settings on the website might be set at U.S. default and not U.K. which would make my average 71mpg.

Hmm, so many factors. I guess a big part of it is my slightly stoppy starty 6 mile commute each way into Birmingham city centre (worse on the way home as there is more traffic).

Time will tell I guess.

I'm not using Fuelly, I just divided my Trip (158 miles) by the fuel I put in the bike today (11.6 litres). That's 61mpg (UK/Imperial).   :006:

The only way this can be done accurately is by filling up to the top, then zeroing the trip meter and waiting until the next fill up, then calculating the tank miles with the fuel put in. When you say you have done 158 miles is that from an almost empty tank?

No, the bike came with some fuel (third of a tank maybe) but I filled it up to the top, reset the trip then did 158 miles, filled her up again today right to the brim (with 11.6 litres) and calculated from there.

61mpg UK.   :006:

If you have only done 158miles since you last filled it to the top how do you know how many miles to the gallon you have done? Unless you fill it to the top again and divide the mileage done by the amount of fuel put in. That is why you do it from tank full to tank full as you get a more accurate reading. Next time you reset your trip meter don't fill up until you have about 280 miles showing or until the reserve 0.0 display flashes.

Eh, that's what I just said I did, I filled her up, reset the trip to zero, did 158 miles then filled her up again with 11.6 litres. 158 miles divided by 11.6 litres = 61mpg. I can't explain it any clearer.

At 61mpg I won't even reach 280 miles.   :153:

I'll bet you have a point there - mpg for short, cold weather journeys in Birmingham traffic ain't going to match our Scottish roads - even those of us who commute into Glasgow.....which I don't....blissfully retired!! 

I went to a concert at Birmingham Symphony Hall this summer, staying close by, and don't ever want to face that traffic again.......

You'll get there, once it's run in and the days are sunny, you'll be boring everyone with mpg figures in the 70's and 80's.  :001:
The Story So Far.........
2017 and 2018: 8000miles recreational use - 89.82mpg UK; 74.79mpg US; 3.14litres/100km
