Alright,.. I've never been measured to know my inseam, but let's assume that I'm the person on the forum who's closest to the ground. (If I measured that right, I'm about a 25.5" - 26" inseam, but I'm reasonably sure it's not supposed to be done by the person being measured.)
I ride a 919 with a seat height of 31.5". That looks to be almost 0.5" taller than the Bandit 1200/1250
I -never- flat foot the bike. I get close in only 2 situations:
1. I have a pillion. I really dislike this option though, because the only pillion I take is my daughter, and when we stop, I have to do a power pushup to keep my chin off the bars. And I hurt for about 3 days afterward from the push ups.
2. I park in a -really- deep wheel rut.
I find that it's not necessary to flat foot both feet. One of the managers at the dealership I frequent told me this:
"Why do you want both feet on the ground anyway? You should have your left foot flat on the ground, and your right foot on the peg, covering the brake."
I had just found out that lowering links were not available for my bike, and hadn't taken possession of it yet ( from a different dealership) He saw me sit on the 919, and had no qualms whatsoever with my ability to ride it.
Since I took possession of it, I haven't looked back. Sure, not being flat on the ground is a little harder when manuevering it around in the parking lot. I just get off it, and muscle it around while beside it. And I've only had one scare in almost 6500kms where I almost dropped it because I didn't have full balance. I've -actually- dropped the Bandit, which I -can- flat foot, with bent knees, on. 3 times.
