How long have you been riding and how long have you had your SV?
Low down grunt is not as immediate but they handle so much better, tip in like a dream and no wobbles when you rag the **** off it exiting a corner. Wind them up and they go like stink, ripping your arms out. At least, my Ninja did.
DO NOT listen to those who say "oh but they have no midrange at all and you have to be at 11'000rpm before they even start going". It's all a load of pap. Most SS600's are fine for commuting and town riding, the only thing you may experience is wrist/back ache at low speeds. But then the SV650S has this just without the sublime handling/braking/acceleration.
