I went from a Harley Road King to a V-Strom. I'm 5'11", but not exactly sure of my inseam. When I first test rode a V-Strom and wasn't able to put my feet flat on the ground it felt really weird and unsafe, but that feeling was temporary. It was just a matter of overcoming old muscle memory. Up until I got the V-Strom, I believed that it wasn't safe to ride a bike that you couldn't put your feet flat on the ground, but I don't believe that any more. When my 800+ pound Road King started tipping over one day while I was sitting on it, being able to put my feet flat on the ground didn't make a bit of difference; once it was going, it was gone. I quickly got used to just being able to touch the ground with the balls of my feet, and that feels totally natural now. 17,000 miles on the V-Strom and now 42,000 on my Super Tenere, and not being able to flat-foot either bike has ever been a problem.
It would be a different story if I could only get one foot on the ground at a time, but as long as I can touch with both feet simultaneously, I'm good.
