R1100RS Fuel Range

Starting with a full tank in the R1100RS and the trip meter zeroed, the low fuel warning light came on at 250km. I don't have an issue topping up with a $20 note each time but after talking with Hilton (R1150RT) on the Nikau Cafe ride on Sunday, he achieves around 500km between fills.Q1: How many bars should be lit with a full tank?Q2: How many km's could I expect from a full tank driving at legal driving speeds?Interested to know of others experiences or advice.Cheers, Alex

Hi Alex,With all the bars on showing on the 1150GS I get 380 - 400k's. The fuel light is on though.I rely on doing 380k's on about 18ltrs.Dave

Thanks Dave, I must have heaps left in the tank at 250k's.Cheers, Alex

Time to start keeping a notebook of km's ridden v litres used, it's highly likely that when the low warning light comes on you could have around 70 to 100 kms left, the fuel gauges are not known for there acuracy, so check it out for your own piece of mind.

Arent those 1100S specs ? RS is 10kg heavier and has a bigger tank 23 litres from memory which would give a 500km  plus range  to a full tank compared to 400 odd from the 18 litre 1100S tank , assuming both are achieveing the claimed 4.3l /100km

A good source for specifications of BMW bikes is Phil Hawksley's BM Bikes site. The specifications for the R1100RS is at:http://www.bmbikes.co.uk/specpages/R1100RS.htmAs BillyBM says, the tank capacity is 23 litres, and wet weight is 239kg.It should be possible to get about 350 to 400km from a tankful before the reserve light comes on, assuming about 5 l/100km.

Different specs for different countries? Not even! I just “Ctrl+C and then centre button to paste (Linux, you see)” from a US site, without cross referencing it. And it seems they have it wrong,  because when I refer to my handbook, what I posted is word for word from the R1100s book, including the dimensions and mass, as you point out. Ain't no RS as light as an S, to be sure, to be sure. And very few modernish Beemers with as small a fuel endurance as an S, either.My last big trip averaged 4.9032L/100Kms, dangling the panniers and with my tent dragging around on the pillion, and if somebody tells me an RS has a more economical fuel burn rate than that, I will readily believe them.Sorry about the misinformation.

The Hawksley site is really good.On the topic of fuel consumption I was looking at an Aprillia RSV Mille as an option prior to the 1100 S. Just how far can you get on 21 litres at 12 litres /100km ? The S seems to manage around  5 to 5.3 l/100k.

When the low fuel light come on is dependent on how the in tank fuel gauge has been setup and can vary considerably between similar types of bike.  It seems that replacing the (in tank) fuel filter can sometimes upset the standard factory setup unless great care is taken. My R1100 RS low fuel light consistently came on between 300 and 330 km and was dependent on use, ie. solo or 2-up riding, and the most it ever took to fill up was just over 17 litres.  Solo riding gave 19 - 21 km/l, 2-up about 18 - 19 km/l. As a matter of habit I zero the trip meter every time I fill up and use a km/l fuel consumption measure to easily estimate how far I can go when the low fuel light comes on.  A l/100 km measure is not an easy, or useful, figure for mental arithmetic calculations while riding, or any other time either in my opinion  😛

Many thanks everyone for your sharing your knowledge. Yes indeed, it would now seem I had plenty of fuel left at the 250km mark. Thanks brianz, I will make a point of zeroing the trip meter at each fill as you do and will stretch a little more each time as I look to average 450km on a lightish throttle.Hope you have all enjoyed our brilliant xmas weather.Cheers, Alex

Would it not be possible to visually fill the tank asap after the light comes on. Subtract the fill litres from the tanks capacity and the result is the litres left when the light comes on.  This works for me.To zero the trip meter on filling also gives a 2nd check on consumption.Most petrol stations will allow a fill if you ask although I now favour self service stations.

I don't see the point. Enjoy riding the bike to it's full potential the little you save by nannying the bike is not worth it. Fuel is such a small cost. I wouldn't know what any of my bikes have run at per 100ks just the distance until gassing up is required.

Yeah Dean, you have missed the point! This is to avoid running out of gas, which can be inconvenient.

I was generalising as some tend to get hell bent on saving fuel and not enjoying the performance of there bike or car.
