I have never taken the Tuono to the track bikejunky. I know I will get carried away and I really don't want to lose her. I have been casually shopping for a track bike like your SV650 to beat to death, but other obligations have pushed this to the back burner for now.
I too love the V-twin power response curve. The new 4's are getting better at smoothing out that inline 4 power surge which, as an old 2 stroke guy, I have to admit is addictive. With traction control the V twin advantage may disappear one day soon. We'll see.
