Hey Luftmech,
I ride the SV locally and at the track. Haven't yet turned it into a dedicated track bike yet, but the thought has been on my mind...I've also thought of getting a second one, if I can find one cheap, a bit beat up, and converting that into a track only tool so I can keep a the nice one for the street. Hmmm, all I have to do is convince my wife I need it :wink:
Honestly, for just around town, I don't think a guy would see as much benefit from having the 1K's extra power, the 650 is pretty quick on it's feet, as much as I need on the street. However, nothing wrong with the 1K either, especially if you can find a good deal. Good luck with finding the right bike for you. You're definitely doing your homework, so you will.
