I'm short too... and mid-50's, not sure if that qualifies as old fart around here or not. I'm 5'7" with 30" inseam. What I've done to lower the WR:
1. Factory lowering adjustment (gets you about 5/8 inch)
2. YamaLink (gets you about 3/4 inch)
3. Fork tubes pushed up 1 inch (compensates for suspension geometry changes from the above)
4. SeatConcepts low seat (gets you another 3/4 inch)
All of the above in combination nets you a little over 2 inches, and when if your sag is set properly the bike will drop another 2" when you sit on it.
With this, I can comfortably get the balls of both feet down when on level ground, or slide a bit to one side and flat-foot one foot.
I'm actually thinking about putting the factory adjustment back to the stock setting and pushing the forks back down about half an inch. I've found the bike is so light compared to the DR650 I was riding before that I really don't need more than one foot down.
