    So what range are you guys typically getting before fill ups? You've listed miles to empty, but when out on a ride I never push my mileage to the last drops if I can avoid it. On my Weestrom that means filling up between 225-250 miles on a tank. That typically leaves me about half a gallon as backup. I watch my gas gauge and as the last bars drop I can tell pretty accurately how my mileage has been and how much fuel I have left.

    What's your typical fill up mileage?

    -Stock gearing, exhaust, windscreen etc
    -no luggage
    -odo 1300km
    -6'3", 240lbs
    -40-43mpg for the first several fills
    -52mpg on the last tank

    Been filling at the same station, same grade and have been riding the same % of city and highway so I'm not sure why the last tank jumped so much (not upset about it...)

    In my first post after the first 500 miles I averaged only 30.3 miles per gallon.

    At this point I'm averaging 49-54 mpg pretty consistently and calculated with a calculator not the OBC. No issues with the OBC mileage readings though but after running out of gas the first week I give it plenty of respect/cushion, have the fuel range set on my GPS as a reminder and now carry two MSR fuel bottles in DV and off-road.

    I'm switching to TKC 80's next week so it will be interesting to see the difference for my around town stuff.

    Good stuff, guys!

    If you're interested, there's a website - www.fuelly.com - that keeps track of your vehicles and MPG. It's also accessible via mobile devices, so you can update right at the pump. I'd love to see more data there (hint, hint).

    Bone stock except a storm topcase, 2k miles me at 250#. OBC shows around 51 mpg steady but fuel sender is kind of wonky and a new on on order. Actual mpg for the last two tanks using miles divided by gallons has me at 55.4 and 55.6 mpg. Most 60 mph back roads with a few miles in town each day.

    I have been averaging 54 mpg. I now have 3500 miles on my F800GS. I love this bike. :D I live @ 5,000 ft. and today did a ride to 11,000 ft and back. It covered 143.7 miles according to my gps from fill up to fill up. (1/2 mile from my house). The bike took 2.116 gallons of gas for 69mpg. Yes I rode easier than usual but didn't baby it. Those are Vespa #.

    I have averaged 50mpg for the last 3000 miles across a wide range of riding conditions from serious dirt (where I am slow) to twisty pavement (where I'm not). I live at 7000ft & often ride higher. I don't think the bike's been ridden below 6Kft yet in fact.

    I've had no issues with the onboard computer. It seems close enough to be useful, and has so far been consistent (ie: reliable)

    On return from my 3,400 mile trip that took me through virtually every altitude and condition, I can report that the mileage that this bike gets is VERY dependent upon speed. Not temperature, tires, luggage, or any of that stuff. If I was doing 80mph on the highway I'd get 47mpg. If I was doing 60mph on the highway I'd get 55mpg. And the only area where load actually seemed to effect the milage was when I'd pass through the mountains. Then I'd get 45-47 on the way up, then as I'd be descending I'd get 80-130mpg.

    Point being: you could cruise all day on this thing at 55-60mph and easily get 250 miles on a tank before the fuel light comes on. But if you insist on (like me) cruising at 70-80mph then you're only going to get 160-180 miles out of a tank when the fuel light comes on.

    I just spent the week on a liesurely cruise through the Kootenays. The speed was low, averaging 85 kph I'd guess (one guy on a DRZ400). Loaded with about 75 lbs camping gear my average was 3.8L/100 kms. Not sure what that is in MPG, but I was surprised to use less fuel than that DRZ!! :wink:

    My typical mileage is still holding around 4.5L/100 kms...

    I have been averaging 4.6 litres per 100 Km over 8,000km ... but last fill:eek1

    A mixture of main roads, gravel roads, forestry roads and cruising at about 110 to 120 km on the GPS, with the last 30 kilometres in the dark and rain at about 90 -100km/hr = 3.7 Litres per 100 Km or 77 mpg imperial.

    For you Americans I believe that works out to be over 66 mpg! :clap

    I did 454 kilometres on the tank (276 miles) and added 16.76 litres

    Just type it in Google:

    "3.8L per 100km in mpg" results in:

    61.9mpg (rounded)

    cug - likes Google for all kinds of conversions like "129 USD in EUR" or Fahrenheit to Celsius.

    Over 7000Km and still haven't press reset on the average since day one!

    And it just went today from 4.8 L/100Km to 4.9 :D

    So yeha i'm happy!
    Agressive riding on tarmac, avoiding Highways (less then 200Km on highways for sure!) and the ocasional weekly off-road('ish still on batllewings) ride!

    P.S: Stock windshield, Large handguards, 1.83m (6'1 or 6'2 ?!), and always with cross helmet (A.K.A big-ass-aerodinamical-air-break, or just neck-braker)

    New bike, rode it pretty much regularly for the break in period - a mix of everything.

    Bone stock, no bags other than a camelback.

    Before 600 miles service avg about 50mpg.

    After 600 mile service I avg about 53-54 mpg consistently. The OBC rating seems to be about right on give or take a mile per gallon or less.

    I'm happy with it.

    7,000 miles on the bike, 40L Caribou Cases, mix of dirt mntn passes and paved canyons (30-80 mph), running at 6K-10K ft altitudes on mid-grade gas (87-89 octane) yielded a best tank of 67 mpg. That is measured by fill-up/mileage, not OBC (which really means nothing at all). That's a pretty comfy 250 mile range.
    in 1300 miles over the weekend, which included top speeds of 115 (shh, don't tell anyone), i never saw below 61 mpg. most tanks were 65-66 mpg. higher speeds and stops/starts seem to be what drives the mpg down into the 50s. Also, bike seems to get much better mileage now that i am back home in the clouds, rather than having to slug it out in the low lying flatlands.

    Filled up in Lee Vining (Mono Lake) torqued up thru Yosimite 35 to 45 mph (park speed limit) A couple stops for pics, over Tioga pass and out the west side down to Oakhurst.. This is the truth part... 146.7 miles... 2.03 gal.. = !!!
    Ok. So that was an exception..

    I do get 60 mpg fairly often, mid 50's freeway speeds ( 5k rpm / 80 mph indicated) or 75 - 80% effort in the twistys...

    A trip thru Nev back roads next month will give me a realistic off road milage.

    Jessy bags, tailbag, engine guard, and 190 lb rider.. using 89 octane.

    mine is stock, with a couple extra pounds of air in the tires, since I field dress about 240. 1300 miles on the clock. average 58 mpg. Assuming the odometer is correct and doing the math at fill up. Best tank was 62 mpg. Worst 57
