Another variable to consider is ethenol fuel as opposed to straight 100% gas. Ethenol is cheap gas, but ruins my mpg, by as much as 20%. I'll go out of my way not to use it if I can. Sometimes you can't help but to fill up with it, but I avoid ethanol when I can.

E-10 is about all I can find in my area anymore and my Versys mpg is down about 10% over the last few tanks.

Also I've found average temperature and altitude can make a huge difference. I've seen variations based on either as high as 20% with my bikes (I don't have an F800 but it would likely be similarly effected).

Wink Average 58 on 87 octane

I have over 1,400 miles on my F650GS and I generally average 58 mpg around town and in the mtns.

On Sturday evening I took a 240 mile ride on the freeway and averaged 51mpg, but I had pretty strong headwinds on my return home on that trip.

How accurate are the speedometers / odometers? Traditionally, BMW meters have been waaay off.

If you base your MPG off a faulty odo, you're gonna get a bad number.

Anybody doing this calc with a GPS?

With no bags on, I've been getting about 48mpg computed from the odo, and this is with mostly tame riding to work and back (5 miles of fwy). Was figuring on better than this...it can only go downhill when I put on a load.

Milage

5'-7, 165 lbs, 800GS, TT 41 liter bags, nearly all rural riding and "brisk" paces. Use GPS for mileage, worst, 54 mpg, best 64 mpg. Very consistent at 56 mpg.

In a review on ridermagazine.com:

Quote:
BMW claims great gas mileage for the 800--62 mpg at 56 mph, and 45 mpg at 75 mph--for a potential range of 260 miles with the 4.2-gallon tank.
Since you get run over around here if you're not doing 75+, I tend to do a70-75mph most of the time. Given the mileage I'm getting (46mpg), this is consistent with the quoted claims.
