I've used a Sigg camping fuel bottle in the past. Whatever they used as a gasket didn't like premixed petrol so I replaced it with one cut from nitrile rubber - been ok so far.
The extra 1L is worth it for me -gives an extra 40+ miles range, but then my machines barely count as motorcycles.
MrE-
The DR does around 14-15 miles to a litre, I think. 60-something mpg, depends on riding environment.
So minus spillage, idling etc, I’d need to be sure I can safely reach a garage within 10 miles. That feels way too limited, especially on a byway where you might waste half that fuel just getting out to the nearest main road.
The XJ is less efficient than that. Can’t remember exactly, I think mpg was in the low 50’s with how I’m riding. 2 litres on the road would guarantee a Shell, or at worst a Texaco garage.
So far, the DR will get to 200 miles on a full tank (Acerbis 16L) so I just refuel around 160. Similarly, the XJ hits reserve at about 150 miles, so I flip the tap at 140-odd and aim for the petrol station.

The Givi is available for under £16 inc post on ebay. It is the largest.
I paid £16 through my mechanics for a 2L with the smaller spout and it’s sat unused. You need a funnel to fill it up, which is my main reason for leaving it at home. Send me a message if you want exact specs.
Edit: the Fantic owner friend was planning to use an alu 1L (camping) fuel bottle, but I think on anything bigger than a 250, 1L is nigh on worthless.
