I've searched for a while because I thought this challenge had been raised somewhere before.
Anyhoo- here's my story:
Riding back to Rocky from Eungella I had the low fuel light flash and then display 95 km to empty. Since I still had 75 kays to go I kept a close eye on it, but the 20 km buffer stayed constant. Then at 40 kays to go, it went to "You're nearly stuffed" mode. I figured I still had 20 buffer, so soldiered on.
Overnighted at the motel and knew I'd have to stop at the first servo. About 300 metres down the road, I found it, and the engine quit right at the pump! :eek
I put it on the centre stand (as I do, for consistency :-*) and filled her up. It only took 26.26 litres!! So according to that, there was still 2.74 litres in the tank. That doesn't make sense, does it?
But wait for it... the distance from the last fill at Ilbilbie on the way up was 553 km!
My previous biggest fill was 28.69, the last time I ran it dry. To me, that can only mean the petrol pump was under-reading. It was only one of those one-pump general store setups, so anything is possible.
Whatever the case with the quantity added, the consumption was great! I wasn't riding for economy (you have to sit on around 80 kph for that). My spreadsheets says it achieved 59.5 mpg (in the old language) or 4.75 l/100 km in the back-to-front modern version (21.06 km/litre)

Ha! And just a simple photo could have sealed victory for you... :crackup
Whilst 553 clicks is very impressive - it still looks like (officially) Diesel gets the best fuel economy on a ST with 513.6kms. :nahnah

Just kiddin Bill - I KNOW how ANAL you are with your figures - but that's right up there - well done. I didn't realise until you pointed out that pumps can under / over calculate - much like the air pressure gauges at different servos I guess.
Great to see you out there.

Same thing happened to me Biggles. Got the count down then at 40kms it disappeared. Conked out abt 60 metres from servo with 551.7 on the clock but I didn't take a note of how much went in. Going to pack the trailer this week and take it for a run and see how much extra is used to lug around 120kg.

Looks like Diesel has upped the ante again....................

That's 569kms for a tank villains!!! :nahnah
Cheers, Diesel

I'd like to see you ride that final 58 km before I granted your claim. Common experience indicates this is a theoretical figure.
Riding it down to zero would be more convincing. Beatup and I found it to be misleading.
Go ride it out, big fella and come back and tell us how far you had to push ya bike! :grin
-
525km and took 25.5l to top right up. Forgot to check KM to empty and take photo. Showed 5.5l/100k on fuel calc. Seems to be about the same every fill with over 500k on trip meter and 25+ litres to fill. Never had to put in more than 26.5L.
-
Well big boy Diesel. On the way back from Kalbarri via Walkaway, Moora and lots of other places. I ran out on the side of the road, I had put a can in a pannier before the trip to see what the beaST would do.
This was sitting at 110 to 115.
(http://i1097.photobucket.com/albums/g353/Malcolm6112/2012-10-20161940.jpg)
The country servo, funny that, said I put in 22.6litres. I had already put in 5 on the road side, so 27.6lt.
I don't get so worried now, I leave fuelling to around 500k's.

Odd that you should say that, because when I refuelled in Rockhampton in the account that started this thread, the bike had quit at the bowser, yet the amount added according to the bowser was 26.26 litres. Even assuming there is one litre unusable, I would have expected the reading to have been 28 litres.
Makes you wonder about these bowsers. A BP bowser recently charged me for Premium when I definitely used the yellow hose.
Ask for a Tax Invoice and check your dockets, folks. See if you come up with other anomalies.
BTW, I see the air temp was only 41o. Must be Winter still.

One thing to bear in mind in using all available petrol is that the EFI pump does not like running dry (or the one in the ST11 for that matter) as the petrol lubricates and cools the pump. Best not to run really low all the time. But then again the record for the most traveled on a tank is still up for grabs. Perhaps a challenge at the SA meet?

I agree - but I believe the last litre or so in the 13 is unusable as it acts as a fuel pump cooling/lubing reservoir exactly for this purpose.

Is that a fact, Diesel? If so, good call- that explains why we only get 28 litres at best.
Otherwise, stop making up stories and go pull your bike to bits to prove you're right! Wot thuh

Here's my latest claim to fame achieved today on a run up the Putty Road (braving the swarms of Sunday Road Warriors). Filled up at Colo Heights on the way back.
(http://www.imgjoe.com/x/img0144.jpg)
I claim 584.8Kms on the one tank with the refill being 25.12lts
I think that beats Diesel's 569k hands down and to top that off, most of it was done 2up
:nahnah

Damn! That's good Yewie! :-++ :-++ :-++
I was impressed that you got that on the Putty - let alone 2 up!!!! :eek
You'd have to be mad not to own one of these wouldn'tchya? :rofl
Cheers, Diesel
PS - great photoshopping! :eek
Juz kiddin! Well done mate. :thumb

Dick, you were a week late with that ride :p
-
Yeh! Yeh! I know but I just didn't get back from up the coast (Including the Dorrigo RTE) in time to make the Grey Gum last week. Sorry!!!! >:()
-
Here are some photos of my fuel gauge while returning from Tasmania.
I fuelled up in Dubbo and when I was 45k outside Boggabilla when the 50k left warning came on and these are the pics from the Shell servo @ Boggabilla.
The distance from Dubbo to Boggabilla is 493 kilometres.

Since this is the only "ST range" thread on the go I hope you don't mind me jumping in.
After following this thread for a little bit I decided to see what the range was on the ST1100.
I thought I was just testing the range :popcorn...little did I realise I was actually testing my stress levels! :o
The bowser light flicked on around 380km into my test, 31km short of work...:eek
Some sweaty palms and increased pulse as I contemplated what might be.
At one point I reached over to lock the throttle and I accidentally hit the kill switch >:()
A quick glance at everything and I soon realised my mistake :cuss
Haven't done that before...did you know that if you hit the kill switch while riding simply placing the kill switch into the run position gets the engine running again...Hmm I never thought of push starting an ST before, now I know it's doable. :wink1
I filled her up after work to find I still had plenty of juice in the tank 5.5L left in the tank.
This gives me the following results:
Range Range
Actual Litres Litres Litres Economy Theoretical
km Capacity Used Left L/100km km
ST1100 411.3 28 22.5 5.5 5.5 512
I was previously filling up as soon as the bowser light came on and depending the quality of the fuel this could be as low as 330km! >:(
I think I'll be filling up at 400km from now on, stress free...I hope.

Its always good to test such things before you have to find out the hard way. Normally I would count on a 450km range at least, with the possibility of going further if needs be and the conditions were right. Going to the Border Run this year there were strong head winds that reduced the comfort zone to not much more than 330kms, which is right up there in fuel usage to a brisk day ride through the Snowy Mountains. My fuel light does not work, but I have my benchmarks to keep an eye on to see how the fuel usage is going. When the needle moves off the full mark to just inside the top white mark that is 6 to 7 litres, half way just happens to be 14 litres used on mine, and on the last white mark is a touch over 20 litres. Every ST11 varies it seems. If the needle hits the red zone there is 4 litres left, but I have to be sure I noticed when it happened or else :||||
-
Furthest that I have gone is 431Ks, and took 25.22 Litres. Most fuel I used was 27.2 Litres for 408 Ks. Now thats cutting it close
-
My best ever recorded result for my 1100 towing my previous trailer was 27.44 litres for a distance of 470kms (17.12 kms/L). From Ceduna to Port Augusta on the way back home from Port Hedland. I had 10 litres of spare fuel but never needed it.
Now with my partner and a larger trailer which we use at least fortnightly for shopping trips my average for this year is 15.80kms/L or a safe 380kms per 24 litres.

I honestly don't mean this as a sledge - but can you see how the computer (EMS - tune as you ride) and fuel injection has made a world of difference?
Brock's ST11 is the last of the line, latest model, (latest development) and still gets 150kms less for the tank that Yewie on his 13 did (I acknowledge the extra litre fuel capacity for the 13) - but looks like there is a general trend here - as that last litre seems to have been worth 150kms!
Biggles was meticulous at keeping consumption records for both his 11 and 2x 13s. Have you got a pertinent comment here mate?
On a 1000km FarRide with Streak (me = 13, Streak = 11) he consistently put less fuel in for EXACTLY the same route - so this upsets the theory in a one-off, (but things evened out when I stopped showing off and put my front wheel back down on the road... ) :nahnah
Seriously though - could it be the old carby Vs EMS F.I. argument that manufacturers boasted about?
Thoughts/comments appreciated.
Cheers, Diesel
EDIT: Don't forget the 200cc extra capacity too - does this equal better revs at same speed because of extra hp/torque? At 100kms (107 indicated) - ST13 with Michelin PR2/3 = 3,400-3,500 rpm
-
Over the years I have seen comments both ways. Some say the ST11 went further per litre, some say the opposite, some say not much difference. I would have thought that EFI in the long run should be better as it stays in tune better, without the wear I have experienced in various parts of the carbs on my bike.
I think that FarRide does not count as there was some problem :nahnah
-
Over the Xmas break, I will put a fuel can or two on the bike, and go for a long constant speed run to see how far to empty and how much it takes to fillup again, Most of my riding involves commuting to work.
-

Ironically - THAT FarRide was the one where I was testing out the fuel additive which gained notoriety on this forum. Since that run I have shown to get 569kms for a single tank with no additive, and just running Caltex Vortex Premuim 95 RON! :think1 hmmm....
@Brock - fair call. Hwy cycle has got to be worth a few extra kms/l.

Exactly why I posted, seeing the economy the ST13 was getting compared to the ST11 just didn't add up for me given the ST13 only has an extra 1L of fuel tank.
As for the speed/rpm I'm doing 100km/h @ ~3400rpm on my 2003 ST1100PY.
I do love fuel economy, another tick for the ST13. :thumb
-
Going by the stats on my best run, I should be able to get 480 Ks out of the tank, hopefully more. I will probably wind up with a sore bum into the bargain.

I'd agree that as an overall comparison between the 1100/1300 the EFI on the 1300 with all things being equal should give better fuel economy.
However, as well know there many variables to take into account, such as lay of the land, speed and wind direction to name a couple. The same bike with the same rider on the same stretch of road on two different days will give different figures as regards to kms/L.

Like you John, the worst my bike has ever done was on that run. On one tank of fuel in that head wind I got 12.71 kms/L but that was towing the trailer and having Heather on board as well.
But the best I've had this year was 19.67kms/L (with Heather no trailer) but my average over 12098kms for the year is 15.8kms/L. So you win on some and lose on others.
-
The best fuel economy I have got was from E10. 91RON is the next best. 95 and 98 RON don't do anything for my ST11 except make the wallet lighter. Fuel economy does not worry me particularly, it is just the range I get from a tank that means I can get from here to somewhere else without pushing.
Unless I am riding with other ST owners, a range of 450kms plus seems well beyond other riders comprehension, so I have to decide whether to fill up when they stop at 250 to 300kms, which is far too early to stop on a decent ride Wot thuh

Thanks for the invitation to share, Diesel :)
On my 2000 ST1100PY I averaged 5.8654 l/100km over 122 refuellings.
My best was 5.0885 l/100km; worst was 6.9854.
On my 2004 ST1300A I averaged 5.9246 l/100km over 72 refuellings.
My best was 4.9769 l/100km; worst was 7.093.
On my current 2009 ST1300A I'm averaging 5.5097 l/100km over 94 refuellings.
My best has been 4.67 l/100km; worst was 6.8281.
Why the variation between the two ST1300s?
One explanation could be the fact the 2004 figures began at 66,590 kms, whereas the current bike began at 5500 and hence is newer and probably more "in tune".
Another factor is I have done much more "out of city" riding on this bike, including two FarRides, the STOC Rally and a trip to Tassie.
I'm also older and much more sensible now. :grin
Darn, while I'm away working my butt off, Brock is whacking it!!!! :eek
-
Looks like on average, you are getting an extra 320m per litre from the ST13 over the 11 - all things taken in - i.e. an extra km per 3 litres - or and extra 9 km per 27lt tank - not any where near the 150 clicks that showed up in previous figures. This would seem more realistic based upon the science of the two machines.
In a nutshell - bugger all difference!

Hows this for fuel Economy 558.6 with gauge showing 59 km to go so should get 617.6km
But I only could put 24 litres to fill it up so I had 5 litres left.
On my fuel Economy converter it says I got 66 mpg or 4.3 litres per 100 km
So if I could use up all of the 29 litres in tank I could have got 670 km km
But I am not going to try

is that US or Imperial MPG??

I think it is imperial as I have a old "TOTAL" fuel Economy converter
the type you slide along and line up fuel used and Km travelled

Yep,
Just did the calcs, 66.19MPG (Imp) 55MPG (US) not too bad at all.

I don't know about riding like an OLD Man but if you keep the speed down to a maximum 80kph you will get this sort of fuel consumption. :blk13 o:) o:)

This excellent fuel economy run was recordered on a run from Toowoomba to Mapleton and return and a ride yesterday from Toowoomba to Esk "had lunch at Esk Bakery" then onto to Blacksoil where I filled up with fuel
The run to Mapleton was normal highway speed 100 to 110 when I met up with Redline and RobJob at Esk on the way.
We did have a lady learner rider with us that I stayed back to keep an eye on, she was riding a Suzuki 500 twin but she sat on 100 to 110 where she could. Then the trip to Esk and Blacksoil was with my Brother in Law on a Harley which is not a race bike
It would be amasing what fuel economy you could get riding at 80 kph maybe someone should try it some day.

But on the way back around the dams wasn't so fuel economical :S. But I must admit, it was a GREAT day out.

It was a good days ride, it is good to get out and go for a ride fast or slow it is better than sitting around the house watching TV

Well the new ST1300 is not as good on fuel as yet, but it only has 7,600km on it so far
I fill up today with similar riding as last time I did 461km and put in 22.95 litres
So only got 4.98 litres per 100km or 56.72 mpg :o
-
Being new to the ST1300 I am frankly amazed by the fuel economy and range. Last 2 fills more than 500ks with a minimum 60ks left to travel according to the bike, so I suspect more. I keep thinking SS1600 with 2 fuel stops, a 50CC with 7 a 100CCC way easier than the last Honda I did one on :fp.
I know I am preaching to the converted, but I am excited and just needed to say it!

.....next add an external tank and you will be astounded :thumb

Can't understand why more FarRiders and IBAers don't see this, among other major advantages of the STs.

:rd13
Economy of bikes seem to vary, out of my mates ST1300s mine is the most economical, possibly because it is run in (170,000klms), I always get over 500klms out of a tank, and if I stayed at the speed limit I am sure I could get over 600 klms from the tank, but I don't know if I could stand going so slow for so long. I change the in tank fuel filter every 80,000 klms (you would be shocked at how much gunk I get out of it,) and run injector cleaner in the tank regularly.

On my way to Middleton last year I got my best fuel economy on the western leg from Barcaldine Qld to Goolgowi NSW 1,330 K's in a southward direction. It could have been that the road was flat and straight or perhaps just maybe it was all down hill..... :grin
