How to fill up motorcycle fuel tank?

Previously with a car, I would insert the nozzle all the in.

However I found when I do it with my Kriss, from meter near E, only 1.5L would go in before clicking.

Is it ok to just put the nozzle in enough it stays in place? Tried this morning and filled up 2.3L from meter near E. A little scary (being noob) I could see fuel near the top when peaking through hole and my meter needle overshot F.

hi guys, planning to get a 250cc scooter but kinda hard to decide, currently riding vario 160

narrowed down to a few, xmax 250, lambretta x250, modenas dtx 250
xmax is the most expensive, followed by lambretta and then dtx

im not planning to ride on highway, just city ride

wanted honda cb350rs but need to go take B full, kinda leceh so give up on that

which of these 3 is more suitable for city ride, maybe just maybe once in a blue moon will take it for long distance

i know xmax is very reliable and quite comfort during my test ride
