Has anyone got info on how the range display on the remaining fuel is calculated?
The manual says it has a usable fuel capacity of 11 litres (approx) and a reserve of 1 litre (approx), it also says that the range indication comes up when the is down to the reserve level. So I was a bit surprised when the range indicator came on the first time, displaying about 80 km to go (ie way more than 1 litre left) - when I filled, I got 7.4 litres in, meaning another 3.6 litres or so left in the tank. I've filled 3 times now and each time, same thing, range comes on with about 80 km to go.

Doing some calculations myself based on the fuel consumption and the amount I put in, it would suggest that the displayed range is being calculated for the remaining fuel not including an approx 1 litre in reserve - giving a bit of safety margin. Does that make sense?

Anyone else got thoughts on this? What is the furthest anyone has done on a tank?

And while talking about refuelling - something else, when you stop for petrol, open the fuel filler cap, hinge it up backwards so you can put the nozzle in - it won't stay up out of the way, just drops back down to cover the filler neck.... grrrrrr (I will have to come up with a fix for this)

I leave the ignition + keyring in the filler cap, this is just enough weight to stop it closing. When closing and locking the cap, I push down on the open lock flap and have no issues re-locking it.

That is what I experienced too
The orange light goes on and the range indicator tells me that I can drive for another 80 km.
The bars on the display still give me two bars left.
My average is appr 33 km/ltr and that means when the light goes on I should have driven 33 x 10 = 330 km
At the moment the orange light goes on and I do not have driven that 330 km it means that I haven’t reached the last liter (smart math !)
I think it’s a safety issue too.

Your problem with the filler cap sounds familiar and is a little ‘pain in the .....’
It’s nothing big but just something they could do a bit better (maby an upgrade for 2018)

I had problems by closing the filler cap.
I have to use the key to close it.
It was not possible to close the cap just putting it down.
I need the use the key to lock it.

A suggestion was to fill it not all the way and I have not tried that yet.
I have to fill the Beamer up this week someday and will try to keep some air left

Leaving the key in is a safety feature of the fuel cap, just fill it up to the cross bar in the filler inlet and you shouldn't have a problem closing the cap. I also tend to get about 7.5-8 litres into the tank when the reserve light comes on. Anyone game to ride it to 0km range remaining to see if they still get the reserve after this?

Today I put 255,5 km on the clock
The yellow light was already on for 60 km.
When I filled It up, I had to put in 8,5 liters.

Average a little over 30 km/liter (normally I do 33-35 km/l.
With a full tank I had to be able to do 11x 30 km = 330 km

I think the yellow light is an extra warming and tells you, When the range is zero km, you start your last liter.

This morning was down to 7KM left as per indicated by the "Range" function. Was able to fill with 8.65 liter. So even if I was very close to 0 KM, looks like I still had 2 liters in the tank... either that or that tank is not really fitting 11 liters. Only way to know would be to ride it until nothing in the tank, making sure to carry a jerrycan with you :)

Fueled up today and with 30 miles left on the range and low fuel light on. I checked the tripometer and had under 130 miles on that tank of gas. Use 93 octane.

Wow. That's a lot less range than I was expecting. How many gallons did it take to fill the tank? We’re you riding it hard?

Edit: I see you’ve got an aftermarket exhaust, so I imagine you’re running it richer than stock.

130 miles, that would be ~210km... That's just about right on how much my tank lasts as well. About ~300km if I'm riding it light, or ~230-250 if I'm stepping on it regularly. Should be just a bit richer than stock, not that much though.

From what I saw on the instant consumption at that speed, the consumption would be 4.2 - 4.4 l/100km or 53.5 - 56 mpg.

On 3rd gear and upwards I find that if I ride consistently at a specific RPM range I don't consume more than 3.5-3.8 l/100km, that is noticeable on 5th gear when I ride at 5k-5.5k RPM and I frequently get 3.1-3.3 l/100km which is insane. At 110kmh, that should be about right; 4.2-4.5 l/100km.

Refuelled today with remaining range down at 6 km, took 9.15 litres - so still not down to the last litre.

One thing to note is that the range calculation is based on the average fuel consumption - which can be higher than what would have been recorded for that tankful if you haven't zeroed it for a while... (I hadn't)

The average fuel consumption that my range was being calculated on was 3.5 l/100 km, my actual achieved worked out at 3.15 l/100 km - if I had zeroed when I last filled, the range calculation would have been closer to 95 km, which would have made it closer to having one litre left when it displayed 0 km range.

I zeroed the average consumption display this time, will be interesting to see what happens.

(3.15 l/100km works out to 74.7 miles per US gallon, 89.7 miles per UK gallon)

A close call

Pulled into the Servo just as the distance to empty flipped to 0 klms. So glad I did not try to use the '1 litre' reserve to make it to the roadhouse further down the highway. :crying:



This was after travelling at 90-110kph for pretty much the whole tank on the 310 GS. Average consumption was 4.1 l/100k at these speeds. I watched the instant consumption to pass the miles and concluded that @90Kph 3.5 l/100k, @100kph 3.9 l/100k and @110kph 4.5 l/100k. This was with a reasonable amount of luggage.

Once a while ago, I've reached (and passed) the zero limit. It was sort of an emergency, so I had to reach home before refueling.
I´d thoght that I'll have to push my bike to the Service Station, but no. I still ride a few KM and arrived driving to the service station.
Right now I can't remember how much did I refueled, but it was less than 10 litres.
Normaly I go to the station with less than 10km left on the range indicator, and never refueled more than 9,8l (I'm using Fuelio for loging mileage and consumption ;) )

Here at Santiago distances are relatively short, but the average traffic speed isn't higher than 30kph (18.64mph) , so my fuel consumption isn't the best (~4,5l/100km, 22,22 km/l or 52,269mpg).

Resuming, I don't know how the remaining range it's calculated, but I can tell you that when you reach zero, there's still some km to ride.

Yes, from mine and other peoples experience now, I think the answer is as follows...

The "Range" indicator will come on when there is approx 4 litres of fuel remaining in the tank.

The calculated distance shown is how far you can travel before the tank gets to the reserve amount - ie when it drops to zero, there would be approximately still 1 litre of fuel remaining in the tank.

The calculated distance is approximate, based on the average fuel consumption (as measured by the on board computer) for approx 3 litres of fuel.

Just reporting the same thing. Topped up with 1 bar on gauge. Light went on when it hit 2 bars. At 2 bars it said range 84km. Topped up kust over 7 litres.

Tank lasted about 240km.

All,
Just a friendly reminder, try to avoid going into the reserve "arena" especially in hot weather. The fuel pump can be damaged if you do so on a regular basis.

Here is why. The fuel pump in the tank pumps more than the fuel injector needs so the excess fuel is recirculated back to the fuel tank.

The issue is that as fuel is pumped, it warms up in the pump. If there is not much fuel in the tank, the fuel gets warmer and warmer as the excess fuel recirculates because you do not have the buffer of cool fuel in the tank to keep things cool. You would be amazed how warm it gets. This is not good for the pump and can reduce the life of the motor which is not good!

So just try to fill up on a regular basis before it gets down to the reserve level. This will help you get good life out of the fuel pump!

Very interesting... that was indeed lucky. That goes against all the experience I have with my G310R - even when I went 5 km past the "range 0 km", it was only 9.5 litres to fill.
For those that don't know and maybe are interested, if you do go past the range 0 point, the range display only shows dashes, no numbers...
