Title: Fuel economy poll ST1100s (seems only fair)
Post by: Sim on March 11, 2012, 05:55:48 PM
Seems only fair if the ST13's get a shot at this that the ST11's should reveal all (see equivalent ST1300 poll if you own a ST13). Give us your overall average (highway and city averages only). No fudging the books now.  :nahnah

Included MPG for those from the 'old' school - happy Kev?

My 2000 ST1100P which I sold in 2009 returned an average of 17.18 km/litre, median 17.35 and ranged from 13.88 up to 19.65.

On the higway doing the right thing mostly I expect at least 18kpl, but it can go to 20kpl quite easily.  I don't do much around town but with some sprightly mountain road riding 16kpl is what I would expect. All figures are solo only, with perhaps some camping gear on.

My figure relates to stop start riding to work n back. On a good run I get 18 to 20 ks/l

I have a spread sheet to work it all out if any one would like it. Its set up to 2017.

My last years average comsuption was 18.01ks/l with usage varying from solo, two-up, and solo with trailer. About 6 two-up trips to the city and the rest all country.

Worst figure 11.59 ks/l  Best figure 19.61 ks/l

4. Accuracy of the speedometer/tripmeter..

When I compare my GPS distance to my bike's trip meter there's not much difference but actual speed is about 5kph slower than indicated @110kph

Its the front tyre that drive the speedo on the 1100 Kev.  Those speed check devices are not so good on bikes as the target area is too small. They had one at work once, and it didnt register a bike until you were about to pass it. I'm also betting that they set it to read high to slow vehicles right down.

Post by: saaz on March 11, 2012, 08:22:21 PM
I went through one of those speed indicators recently, the one just out of Wodonga.  It was way off in the car, showing at least 5kph less than I was actually doing.  My car speedo is spot on and the GPS agrees.  Some might say it is set low to get you caught by the speed cameras later....

The police bikes have the same speedo drive as the civilian models, and both are accurate distance wise.  Civilian speedos typically read faster than what you are actually doing.  Mine is an ex NRMA but police spec bike, and it reads a bit high on the speedo. I suspect that it has not been properly calibrated, as it was not in police use so no need for that expense. Police speedos have 2kph speed intervals on them.

Thanks Brock excellant record keeper/book.  :-++

And Kev... re:

The production shall be deemed to conform
In the case of vehicles of categories M and N:
0 ≤ (V1 – V2) ≤ 0.1 V2 + 6 km/h;
In the case of vehicles of categories L3, L4 and L5:
0 ≤ (V1 – V2) ≤ 0.1 V2 + 8 km/h;
In the case of vehicles of categories L1 and L2:
0 ≤ (V1 – V2) ≤ 0.1 V2 + 4 km/h.


I translate that to mean "The designer of ANY said motor vehicle shall be deemed to not be held responsible if you speed and get caught"   :crazy
(ie YOU pay any speeding fine)   :law But we knew that anyway.
Cheers,  :thumb

I can't agree with that statement saaz....having used both radar and laser speed detection devices..and yes, humans do get things not quite right sometimes

From what I read vehicle manufactures cannot guarantee that their speedos are 100% accurate there is a tolerance...and that ADR's state that speedos 'must' not under state the speed...but as there is a fancy formula...notice the readings do not show a -(neg) value...so I guess that means 'most' speedos will show one travelling at a speed less than one thinks...

The production shall be deemed to conform to this Regulation if the following
relationship between the speed indicated on the display of the speedometer (V1) and the
actual speed (V2) is observed:
In the case of vehicles of categories M and N:
0 ≤ (V1 – V2) ≤ 0.1 V2 + 6 km/h;
In the case of vehicles of categories L3, L4 and L5:
0 ≤ (V1 – V2) ≤ 0.1 V2 + 8 km/h;
In the case of vehicles of categories L1 and L2:
0 ≤ (V1 – V2) ≤ 0.1 V2 + 4 km/h.

Cheers :beer

Kev

Well, all I can say is that compared to the car digital speedo which agrees with two GPSs I have that the highway speed sign on the Hume Highway going from Wodonga to Melbourne was way out showing lower than actual speed. It has been like that for a while so why I don't know.  I would have thought that the incentive was to show you going higher than actual, thereby getting you to slow down.

Those formulaes show that at best a speedo can be dead accurate (ie V1=V2), but that the speed displayed can be more than actual but with an upper limit (eg for the first formula if actual is 100kph speedo can shows up to 116kph).  So if a speedo shows the speed limit you should never be speeding.  Interesting as I thought that showing 10% over actual speed was the limit, but it is worse than that. No wonder all these cars slow down when I come up behind them and slow down even if they are below the speed limit - they think they are speeding a lot  :crackup

I suspect you do more commuting than the average ST1100 owner, although you're at the lower end of the median range.

As they say "when you're on a good thing, stick with it"........lol

My all time average since using Fuelly (http://www.fuelly.com (http://www.fuelly.com) ) from Dec 2012 is 16.6 K/L but that includes, one , two up and trailer usage which is sometimes is two up and on my own.

I gave up on the spreadsheets and put Driver Diary ( https://play.google.com/store/apps/details?id=com.sweypro.driverdiary&hl=en (https://play.google.com/store/apps/details?id=com.sweypro.driverdiary&hl=en) ) on my tab......covers everything that a paper log book would have.

Between 17 and 20 thou a year, its been dropping a bit each year. Depends on whats happening with the weather at the moment., I dont do the freeway early morning in the rain. Too dangerous.

Mine started getting lower and lower ages ago. I put in one of those carb kits and it became more consistent again, between 18 and 20kpl, most times at the lower end. Average speeds can affect things, as NT type speeds will cut economy, but unfortunately the ST has not made it there as yet

My economy is improving slightly. but that might be the riding more on the freeway instead of the open road.

My long term average (3 years) is 4.85 l/100k, or about 20.6 km/litre. (Km/litre??? some sort of time warp involved there, I feel. In Australia we use litres per 100 km don't we?) - Hey, I've just realized - the bus I drive gets 20.6 l/100k - something freaky there!

I enjoy the power when I use it, but mostly only use the power I need. With any excess, there is always a "right-wrist tax" you must be prepared to pay.

The ST1300 after a battery replacement defaults to indicate km/litre. Pressing the fc/h button until the display is blank and then pressing and holding until it blinks "l/km" and release and wait until it stops blinking. Then it stays on l/km until the next battery replacement. :grin

K/L is much easier for some of us to understand as we used to use MPG not Gallons Per 100 miles.  Some, like me were taught imperial at school only to have it change a couple years later and as estimate it's much easier to convert K/L to MPG by X 4.5 (e.g. 15 k/l x 4.5 = 67.5 K/G which is about 70 km x 6/10 or 42 MPG). Well.....that's my excuse......lol

I use an app on my phone to record EVERYTHING!  and I just found out how to change the read out from lts/100 km to km/ltr.

It rocords all serving costs, repair cot fuel by type ( ulp 98,95 and 91 and eth etc) gives you handy little charts etc and also has a reminder function for oil changes etc.

called Fuel Monitor.

seems to be good for me cause I need to record then and there or else I will never get around to doing it on the old desk top.

Mine (ST1300) on a long run drops to about 5.0 to 5.4. Even occasionally drops below 5.0 l/100 km.

But this is for your 1300 right??

I assume because of the smaller engine the 1100 will be better fuel economy that your big beastie??   ;-*

Yes it is and these stats come from when it's usually fully loaded, so weight and wind resistance brings the economy down.

Sabie,

Did you notice much difference in fuel consumption when you went from you ST11 to the ST13?

Post by: alans1100 on August 03, 2015, 11:20:34 AM
Yes it is and these stats come from when it's usually fully loaded, so weight and wind resistance brings the economy down.
Tail, side and head on winds all effect fuel usage. Also the lay of the land. What might appear as a flat road might be a gentle slope up or down. You can ride the same road two days in a row and get a different figure because of all the variables that can occur.

All one can do is record your fuel usage over a period of time to see what you get for worst , best and average fuel usage.
