I'm 5'4" at 145lbs with a 28" inseam and ride a V-Strom 1000 at stock height. I've rode a stock KLX400/DRZ400 and that's definitely a high horse. You just need to learn to work yourself around the bike when it comes to a stop. Height doesn't matter when the bike is in motion.
If you need to plant both feet at a stop, get a cruiser.
Take the advice if this is your first bike and don't let your ego get in your way. I can guarantee you you'll trash a brand new sport bike without having experience. I've seen it all the time being in the military. Happens like clockwork when Private Muldoon saved up a years worth of base pay while deployed just to come home, dump it into a GSXR, and then get himself killed because he had no idea how to ride the damn thing.
