Does anyone else find that the fuel consuption computer 'sticks' on 50.4? If I ride hard it drops into the mid 40's, but at moderate speeds on my own or with swmbo (she's about 8 stone only) with full vario kit it goes up to 50.4 and never moves. It seems strange it never goes any higher. Is that the limit of the bike and I'm finding it or perhaps the limit of the computer?
 
Take the bike up to speed, reset the fuel consumption computer and immediately ease off the throttle for a while. Your fuel consumption should soar over 50mpg, at least for a short while :D

I seem to average 56ish... (1200RT)
 
Mine was showing 54 avg this afternoon.

Did a reset as I went on to a bit of dual carriageway as I'm curious about higher speed mileage,

Over the next 25 miles did......

50.4 mpg!

I kid you not.
 
43 on mine all time in town or on a run hope to get more as it frees off just coming up to 5000 miles fuel pumps ok though:blast
 
46.3 or there about if u reset it u can get it to show more but the range goes mad JJH

54 all the time :eek:
 
After yesterdays rideout with the sportbike crew - 48.7mpg

After todays bimble on my own - 51.3 mpg
 
Ummm.... Stupid question - how do you reset the average fuel reading????:augie


P

On my GSA with 'computer' cycle the display to average MPG with the info button then press and hold the info button until it resets.
 
consistently settles down to 42.8, when reset takes a bout 30 miles to settle back down to 42.8 mpg,
 
My current 06 1200GSA with Remus pipes and can (baffle in) always a top case attached to the bike averages 48.7mpg it will go higher if I reset and bimble for a while,it has gone much lower 1000 miles in a day 2 up with full luggage cruising at 90-100 got a figure of 43mpg,but left to it's own devices it always settles back to an average 48.7mpg
 
My new GSA says 47mpg - it said that from when I got it, and how I ride doesn't seem to change it.
Did an "enthusiastic" 375 miles on Easter Sunday and got 47mpg!

Thanks

Thanks for the responces. I think they must just settel into a groove (or is it us?) but I will try a few resets to see what effect it has. A slightly silly but fun diversion, I think most of us become a bit obsessed with fuel consumption when given a means to check it. Mine is mainly trying to make best progress for the least fuel used, very Freudian (or perhaps Scroogian).

Thanks again
 
My K1200S also reads 42.8mpg on the display, this equates to around 40mpg when calculated properly over a few tanks worth of petrol.

This will probably open me up to a barage of abuse, but - the omly time I managed to get better (48mpg on comp) was on a week long trip to Scotland last year. Do I generally ride too aggressive, or inefficient that gives me 'normal' consumption (for me 42.8), or is it the fact that my commute form 7oaks to Canary Wharf just bumps up consumption 15-20% compared to some posts in this thread???
 
47 regardless of how I ride or whether I have a pillion or not :nenau

It really is very easy.

Assume that the odometer / mileometer is accurate.

Assume that the petrol pump is accurate.

Take a note of the elapsed mileage at each refill.

Take a note of how much fuel is put in at each refill.

Do some some simple sums. Number of miles driven by the number of litres inserted.

Annoyingly, the petrol retailers have moved onto a metric scale, while we remain in miles. Then convert litres per mile into gallons per mile, using the simple sums of 1 litre per mile = 0.219969157 Imperial gallons per mile.

That will give you a reasonably exact fuel consumption in miles per gallon.

Repeat several times, to give a reasonably accurate average figure.

Compare your findings with BuMW's computer reports.

Repeat as and if you feel necessary.

Tell us, if you must, the answer.

OK - You asked for it!

56 Plate R1200GS - averaged 50.44mpg over 9548miles at cost of £830.00
08 Plate R1200GS - averaging 48.63mpg over 8855miles at cost of £879.41

For comparison

06 Ford Focus 1.8TDCi - averaging 46.24mpg over 52418miles at cost of £5,329.46 (I don't pay for this one!)
1971 Land Rover Series 3 (2.25ltr Petrol) - averaging 17.6mpg over 7490miles at cost of £1,678.46

So 50.4 for an "old" model R1200GS is right and a bit optimistic for a "new" one!

Is that my anorak over there????

You missed:

Enter all this data into a spreadsheet; include price per litre per fill, calculate and highlight any cost changes at the pump, try to use the same garage for every fill. Bonus tears for showing actual fuel cost less Vat theft.

Produce a Presentation (PP or KeyNote); 3D graphs minimum.

Provide a Weekly update via your Blog.


Or ride the thing, fill it up and enjoy yourself.

Failing that, buy a F800 series bike and get used to ~60mpg and demand BMW produce a F1000GS.
