From memory , standard seat height on the Scrambler XE is 870mm and I think 1250GSA is 880,so very little difference.
I’m 6’1” and my XE is just fine. Twizz is 6’8” I think !!
It looks odd in that pic as BMW and Yam on main stands and their huge fairings make them look larger.
Agree with Arsey plus the Scrambler seat is a lot narrower making the 'stretch to the floor' a lot easier.
Although it's not obvious from the picture, the Yam is the easiest to 'flat foot' I'm 5.11 with a 32inch inseam
