I typically get to 315-325 before the light comes on with approx 65k's to empty at that point........computer usually sits between 3.9 and 4.1 L/hundred

Pretty happy with that

 

That's good mileage Craig. I haven't really stretched to see what I can get out of a tank but it's nice to know when I hit the wide open spaces.

 

I've done nearly 20k miles on my 2012 F800r. I'm getting a dash reading of 62 miles/uk gallon. How accurate that is - I don't know! On two occasions last month when hooning around the Pyrenees in Spain I saw 185 miles on the trip before the dash switched to 'Miles since going onto reserve'. so I think 220+ miles from full to completely empty should be somewhere near the mark. If you divide 220 by 16, then multiply by 4.5, it comes out at 61.8 - so the dash reading look about spot-on!

 

I am a weekend rider usually 125 to 150 Ks. (always reset trip to zero every time i fill up) ... so one weekend forgot to fill up and went for a longish ride and return was up a gorge and the reserve light had come on and I was really worried especially the last part of the trip was uphill. Anyway got home and it was 291 Ks and then the next weekend rode out to fuel station another 5 ks. I did not have the guts to check if it would do any more. So I know it did 296 Ks that one time. These were not stop start commuting type traffic but back roads and hills. (Ks are Kms) Cheers[]

 

F800r with schnitzer exhaust and bike is total 13k km. I’m a calm rider and my consumption is avr. 4,1-4,3 lt/100 km

Funny you should start a thread about this, I've been looking at this question with mine.

So my 800r has done a little over 10,000 miles. Recently I did a 40 mile or so journey over hilly (not mountainous!) terrain, riding as frugal (barely taking it over 3000rpm) as i could; the bike did 67mpg!

Next, cruising over 50 miles on the motorway at 70mph gave 60mpg. A little more speed gave me a little less mpg, if you're getting my drift! Haven't seen it get below 48-49.

However, my average mpg with my current riding style returns 53-54 which, coincidentally is the same mpg figures as stated in the Motor Cycle News review page for this bike.

Something to keep in mind though, I do live in quite a hilly area... namely Cornwall.

 

Over 45 000 Ks tracking and 191 fillups on Fuelley, I am getting 4.4

Fast but smooth rider and generally keep my revs below 6000 RPM.

Best tank was 320 ks but the light had been on for a while.

 

I'm averaging 48.5 miles per gallon at 15.5K miles. At least half of my miles are city(ish) miles. Riding a '12 R model.

And like Warren Zevon said ("Enjoy every sandwich.") I enjoy every mile.

 

Measured mine last week, 181 miles 3.1 gallons. All commuting miles.

 

42000 miles on my 800S, computer shows average 69mpg. Always get over 200 miles before refilling. Bikes only used weekends, long rides in the moors and dales

 

Here's another question. Does higher octane fuel rating decrease fuel consumption? The BMW manual recommends 95 RON (91 AKI). Here in Australia 98 RON is available at most petrol stations so I mainly fill up using this. Probably thinking the bigger the numbers the better. I've occasionally filled up with 95 RON and noticed no difference in fuel consumption or performance.

What are your thoughts?

I have definitely seen a difference between the old 91 and 95 in cars- and definitely better mileage actually recorded as part of a test between a few mates a few years ago (actually in 2006) [what started it was one mates cars was pinking (pinging) and so he was told to try higher octane and it reduced the pinking] however we did not find any great difference when using 98 from 95 in terms of mileage - go figure. I have only ever used 95 in the bike.

 

Will not have any effect. People tend to think so, based on marketing speak of the oil companies... but this is just to justify the higher prices (and increased margins, of course)

 

My comp (F800R -13) says 4.6 litres per 100 km on average. The larger chunk on the fuel meter usually disappears after around 200 kilometers and the low fuel warning light comes on at around 270 kilometers. I usually refill the tank at around 300 kilometers, at which point 14 litres or so goes into the tank.

Found this thread (and forum) after reading a review claiming that the fuel consumption of the F800R at constant 120 km/h is 70 mpg, which should translate into approx. 3.4 litres per 100 km. I've never manage to come close to that... Rarely under 4.2-4.3 litres per 100 kilometers at that speed, unless very favourable conditions.

 

3.4 l/100 km at 120 km/h seems to be heavily exaggerated. My average is 4.5 l/100 km (real value, based on fuelling data). At 120 km/h fuel consumption as indicated by the OBC is considerably higher (surely worse than 5 l/100 km).

 

Average 60mpg. The reserve indicator comes up at around 200 miles.
- 2013 F800GT, 30,000 miles.

 

50/50 highway city riding i get about 21 - 22 Ks per litre. thats about 51 mpg US.
Thats on very twisty hilly roads here in New Zealand

 

Only use mine for longer trips away primarily on secondary roads and twisties. Certainly not nursed for good mileage . The average has not been reset for a couple of thousand Ks and currently shows 4.7 litres / 100km .

 

I'm right around 9000 miles on my 2015, and no matter how I ride, I end up right at 46-47 miles per gallon. (sorry, I can never remember how to convert freedom units into km's, or I'd list that too)

 

About 6.0 to 6.2 litres per 100 kilometres Shawn, which is actually quite high. I recently averaged 4.2 litres / 100 klms for a 2,300 klm trip.

Jurgen, I've only just found this thread.
From the trips I've done on our STs, I've mostly averaged around the 3.9-4.1L/100kms ( I don't do much hooning around []).
The best I've ever got from a tank was 405km and it took 15.6 litres to fill it. Those last kms to the servo were starting to get me worried.
As far as fuel types go, I found i could notice the drop in performance with 91 and all 98 did was make the bike pop more on overrun.
Therefore, I just used the 95 for the lives of both the STs we've owned.

 

When you cycle the dash display through the various options, the first one after the temperature is your average speed. My last tank was down to something like 18 mpg for quite awhile. Since I'd done a few miles on the freeway at 60+ mph, that told me I'd been sitting at a lot of traffic lights and traffic jams with the engine just idling and going nowhere.

Freeway miles will get you either really nice MPG (or km/l) numbers...or get really lousy numbers. Back when the federal government imposed a 55 mph speed limit across the USA, they published a lot of graphs showing how the amount of fuel used went sky high as you exceeded 60 mph. It wasn't linear at all. Well, no matter what you think of a 55 mph speed limit, the physics were correct. If you can hold your speed down to the speed limit, you'll generally get pretty good MPG. Which is why our figures go up on back country roads where the speeds are lower and the riding is pretty constant with few stops. But bring your speed up to 70 mph or higher...and the bike acts like a barn door trying to push its way through the air.

Chris, on one ride there was a long flat section of road following a creek into this little country town.
Due to the twisty nature and all the driveways along the road it had an 80KPH limit.
My instantaneous fuel was reading 2.8 L/100kms. It just shows what dropping the speed does to your fuel consumption.

 

Drag (overcome by burning petrol ) increases with the square of your speed. Double speed equals four times drag.
Fun increases with linearly with speed. Double speed equals double fun.

Personally, when on the F800R on a perfect day, on a perfect road....... how does fuel consumption figure in the equation?

Go enjoy your bike!
