I'll side with the people who think the SV might be too much for a first bike. I don't think your first bike ought to be able to do 130+ and power wheelie in first gear. Perhaps I don't think people have as much restraint as KirkP thinks they do.
Also, about touching the ground on an SV. My girlfriend is 5'2.5" and could barely touch the balls of her feet on my SV650S (I figure ride height is the same for the naked model but I don't know for sure). Maybe she has a short inseam. I think 30" sounds like a long inseam for a 4'11" person, but I'm not a tailor so I don't know (I'm just guessing off the fact that I'm 5'10" and buy my pants in a 33" length).
Anyways, I don't want to bandwagon against KirkP, because I think his position has some logical validity, and he certainly seems knowledgeable, but I disagree on the SV as a first bike.
