Impressive. The weight at sub 375, and the seat height really make for a nice ride for shorter riders..lol She would be happy with that. Any other suggestion? That looks really promising.
If she wants more power yet still easily controllable go with the Ninja 500 - its the same seat height and I've actually seen leftover 09's going for like $3500 OTD which is a little less than what a brand new Ninja 250 would cost. The GS500 is in the same boat lots of leftovers at dealers at good prices, Suzuki is actually offering $1000 off and 1.9 financing on all leftover GS500's, not sure if that applies to Japan too though.
I have a ninja 500 which I started to teach my wife on who is 5'2" and she had a problem touching the ground. I think this is a good beginner bike. Keep in mind any bike you buy would probably have to be lowered for her, good luck
