    What should I expect l/100km travelling long distance on fire roads at about 90-100 km/h with 80lbs on the back? Have to plan fuel load
    Thanks

    Your going to have to speak American here. Most guys won't know what your talking about with l/100km thing. I would guess your mileage will be pretty much the exact same as if you were driving those speeds on pavement. Why would it be any different?? Most guys get better mileage on gravel because they are riding at slower speeds anyway. :1drink

    I average 52-55 mpg on mixed forest roads and pavement. I am always good for at least 200 miles. Now convert that.:evil

    Only in 'Merica. Lol. Reason I ask is because of the increased on off on the throttle and increased drag from the gravel
    Thanks

    Gravel at 45-55 mph...... I get 65-70 mpg...... On technical rocky gnarly stuff at 20-30 mph....45 mpg.

    Gravel I get higher MPG than on the slab, because I drive slower. If you are doing equivalent speeds though, I suspect you would get worse on the gravel because of all the energy being wasted (on/off the throttle, wheelspin, kicking up roost, etc,)

    Isn't this going to be a subjective answer? I mean there are variables. For instance are you riding a fuel injected 250 or a 650 with and FCR carb? Are you a hot shot that ramps off stuff, wheelies at will and roosts his buddies or are you an older guy that just putts along?

    Just sayin

    Just clarifying this is this is the f800gs forum, so this is the bike implied.

    It depends on the gravel...hard or soft and loose.

    Hard to say exactly but my guess is 0 to 5%less if the gravel real loose marbles that you have to wade thru...like the Northern american roads just after the grader has gone thru

    I get slightly lower mileage on gravel than I do on pavement. Probably because I like to horse around more in the woods. If I reduce speed on gravel it burns about the same. Keeping it under 80KPH will return the best range between fuel stops.

    I get slightly better mileage on gravel, probably because it usually includes some side trips on slower two-tracks. Speeds on gravel range from 30 to 90 mph, depending on conditions :dllama

    Just to clarify, that's on an F800GS. My DR-Z won't go that fast :lol3

    You mileage may vary depending how you ride. Short trips you might be playing with the throttle coming out of the corners. You will ride considerably different if you have to cover over 200 miles before the next fuel. You will find you are very gentle with the throttle. 200 miles is easy and 240 miles possible with a conservative throttle hand. Plus you can always carry some extra fuel.

    700km or 430 miles between realistic/reliable fuel stops all on harsh gravel and northern road. I will be bringing and extra fuel can just wondering if it will be 3 or 5 gallon. Leaning at the 5 since I want to do the dempster in 2 years

    My GS seems to just sip fuel. I get 200 plus on a tank and when I stop to get gas there is always a gallon left in there. Even tho my "average MPG gauge" always shows "49" I have to think I am getting 55- 60 MPH in mixed riding. I am amazed at the efficiency of this bike. 9000 miles in and it seems to get better every tank..

    I did several thousand miles on gravel last year in South America. Generally I was going 50 mph or less vs. 65 - 70 mph on pavement. Gas mileage was thus better on the Gravel. Grin factor was higher too. Dave

    You live in Saskatchewan and you are asking a question like this? Over 80% of our roads are gravel.
    No difference in fuel economy. If anything it will be better as you will be lighter on the throttle. Now head out of the city next year and ride on some gravel.

    Ridden quite a lot on gravel but the GS is new to me and the ride we are planning is for early in the spring. I won't have much time to get a baseline for the mileage. And for the record, i don't do a lot of miles on grid, i tend to play a little more in the bush where my throttle wrist gets a better workout. Doctor says its good for the arthritis.
