I doubt Honda has made a different tank just for the Canadian 2017 CB1100 EX.
So I am going to assume the tank on my 2017 CB1100 EX holds 16.8 liters .... until I run out of gas on some lonely back road.
The real question is not what the tank will hold, filled up from dry, but what is usable capacity, before the fuel pump intake sucks air.
A carbed bke could be run dry.
Not so with EFI.
Be good to figure that the last 1/2 gallon or 2 liters may not be usable.
Fortunately the pickup tube is towards the rear of the tank, so there is more usable going uphill, versus downhill.

Fired instantly after I gassed up.
So I believe the notion that a fuel-injected engine cannot/should not be run dry is, or has, become archaic. It definitely doesn't apply to that bike. So, why would it apply to any other bike? What exactly happens? Does the fuel pump lose its prime? I think not. Does all the dirt in the bottom of the tank get pumped into the fuel lines and clog the works? I doubt that.
Those were the reasons given in past decades for not running a FI automobile dry. I am pretty sure they do not apply any longer.
