I'm not sure where you are located, but if you're in Northern CA, ride into Corbin and get their dual platform seat custom made. I'm not that big of a guy, and with a 30" inseam the dual platform seat gets me close enough to the ground (no lowering links). The more you ride the bike the more comfortable you will get with only being able to get 1 foot flat on the ground.
New 2011 KLR 620, she is tall.
I'm not sure if the seat height is higher on the KLR 620's than it is on the KLR 650's. Where'd you even find a 620?
