How much fuel does tank really hold ?

I know this sounds a dumb question and I am new to 919's, but I come from a Superhawk where the real capacity of the fuel tank was about 1.5L (0.4 gallon) less than that stated.
I have just filled up my tank after the red light came on and I put in 14L (3.7 gallons). When the red light comes on there is supposed to be 3.5L (0.9 gallon left). Adding these two figures together gives a total volume of 17.5 L (or 4.6 gallons), which is about 1.5L or 0.4 gallon short. What is the most anyone has put into their tank, and does the RLOD (red light of death) actually come on when there is 3.5L or 0.9 g left ?

It holds 5 gallons, the light comes on a bit early.
A lot of us use the odometer to keep track of the fuel level.

The point at which the fuel light comes on will vary. I've had mine come on on my way to work, but not come on on the ride home, some 10 miles later.

I have no scientific answer to how much fuel the tank will hold other than the stated amount by Honda. Perhaps someone who has actually ran theirs dry might have a better answer.

Most I ever put in was 4.5 gallons (Honda says 5.01 is capacity). The low fuel light was on for approx 30 miles before I refueled.

I have actually run mine dry. 19 liters is correct.

I have seen it said about cars, not sure if it applies to bikes too, that there is a certain volume left in the tank for the purpose of cooling the fuel pump. Running fuel injected vehicles dry can produce problems with trapping sediment in the filter or clogging injectors if the filter is ineffective. Manufacturers should probably be providing not just capacity figures, but useable capacity figures.

The 19 liters is all useable. I have had no problem with tank sediment, that is what a fuel filter is for. I recommend only using 18.5 liters so you aren't stuck at the side of the road. Any time I travel I always bring a pop bottle of gas with me just in case. Anytime I have run a bike out of gas, I've been within 2 miles of a gas station.

I ran my 919 dry an hour ago, managed to restart it and limp to nearest station 1/4 mile away where it died as soon as I let of the throttle. I was able to fit 4.94 gallons into it before I got sick of topping it off.

Also, I got caught out in one of Portland's first downpours of the rainy season. Aside from getting soaked, I received a firsthand impression of Metzeler M3's rain capability. I've been contemplating these tires traction for the last 1000 miles, and after today's straighline traction breakaway I've reached my verdict. The Metzelers are nowhere near as grippy of a tire as my previous Pilot Powers. They get real slippery in the rain, something which didn't happen last year at all with the Michelins. Mileage on the M3's is around 1500...

Very true. I should clarify. Raining for the last week or so, but this was the first time I was caught out in a heavy rain with these tires. It had rained plenty enough to wash away most anything on the road.
