Fuel mileage on gravel

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.

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

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

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

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.
