As noted above, the reserve amount is about 1.5 gallons.  If I fill up soon after the "low fuel" screen pops up, I consistently fill with 4.5 gallons.  So if there's one sensor that seems right, it's that one.  Though it also means I have another 50+ miles to go before I need to get nervous.  Other than that, I watch the elapsed miles on the tank (reset with every fillup) and the current tank's average mpg (also reset with each fillup). The average mpg may or may not be accurate, but it doesn't matter.  It's a barometer for my pattern of fuel consumption on that tank.  If I'm doing a lot of highway, carrying panniers, and going into the wind, I know to be more cautious about my range after hitting the low fuel warning.  Relying on the fuel gauge risks being out of tune with how the motorcycle is operating. It can be a backstop if you forget to reset the meters, but I wouldn't rely on it once you are in to the last 1.5 gallons.

The estimated remaining range is unrealistic - way too high to start and way too low to finish.  I mean, the low fuel warning is at 0 miles remaining, so it has to be wrong.  Somewhere it must be crossing the exactly accurate point, but it's not realistic most of the time.  My gut sense from watching the gauges is that it's around the 120 miles remaining mark. I've been deliberately avoiding testing that theory.

I thought that the book states the reserve is about 3.9L (1.03US gallons or 0.86 Imp gallons)?

Anyway.

I have drilled my filler neck, fill on the centrestand, and watch as each bar disappears on the gauge as it relates to 'Trip A' - reset at every fill - for comparison. I note the point at which the last bar flashes. Here in Oz, my 2010 starts to count 'up' at that point, when an extra 'F' trip counter appears, rather than it guessing how far I can go. I use that moment to check the 'Trip A' for a rough relative guide to my fuel usage over the last few hours of riding. eg 325km is normal, 310km a little low and 360km last week very economical. My routine varies a little from most at that point because I then I reach back and turn the tap for an extra 4.5 gallons in the auxiliary cell on the rear seat to flow.

I've become well used to my bike.

But I have 5 bikes and have had dozens before that handful. Gauges are all over the place. Some start to drop almost immediately eg my FJR; some don't seem to move for ages, then look out, because the gauge starts to move as fast as the tacho heading toward empty eg my Honda Blackbirds.

A while back I had a BMW F800GT. That bike had a very funny shaped tank located underneath the seat. Perhaps the odd shape(s) make it difficult for the engineers to provide the linear relationship between fuel and gauge that would be ideal for the rider's info. Even so, those same BMW engineers on that bike basically gave up. The gauge (pictured below) features a flattened arrow pointing upward to indicate the tank volume is vaguely 'somewhere' above half full - maybe 100%, maybe 55% - at which time the bars on the gauge start to disappear.

Great info thanks everyone!  Still love the bike, just an odd choice of design...along with the disappearing gear indicator when you pull in the clutch....LOL

Remember the old days - not so long ago - or even if you have a brand new fire breathing Aprilia Tuono V4 1100 Factory.

That bike comes with 175 horsepower, a wet weight of 472lbs , real time throttle and lean angle display, APRC system (Aprilia Performance Ride Control), which includes Traction Control (ATC), Wheelie Control (AWC), Launch Control (ALC), V4 AMP Aprilia Multimedia Platform predisposition, Quick Shift (AQS), all of which can be configured and deactivated independently. 18.5 litre tank, about (?) 4 litres in reserve and a range of about 140miles. You hope.

All that the designers and engineers could come up with for a 'fuel gauge' was a warning light when you hit reserve. If you actually saw the light come on  ::010::. When did that light come on? Has it been on long? Is it safe to leave my bike here in this neighbourhood, I just have to get to the gas station?

TBH I take all fuel gauges with a pinch of salt....

Brim it with fuel... Ride it for 200 miles then brim it again, work out you fuel consumption from there. Do it a couple of times to get an average MPG.. And work out you range less 50 miles for a reserve.

This is my first bike to actually have a fuel gauge! (You can imagine how thrilled I am!)  My last bike didn't even have a low fuel light! All other bikes I've had a low fuel light.

Funny thing about this bike and fueling is if you don't reset your trip meter after fueling it will reset itself after you ride 5 km or 3 miles per the owners manual page 4-12. This is for a 2015 model and I have not tried not resetting the trip meter yet.

You are referring to only the low fuel tripmeter correct?

The level sensor does not understand the change in the shape of the tank as the level declines. Unless you have a perfectly straight sided tank (think cylinder or cube/block shape, this will always be the case.
