No question about it, in fact on a track such as West Virginia Shenandoah the 600's consistently post better times than the 1k bikes. Tell you what, with your wheelbase approaching 62" a Kawi 250 Ninja will spank you on some circuits. Shoot, that wheelbase is more than 5'!!!
On the Dragon, I am pretty sure I will spank you with my dirtbike using Supermoto rubber.
In a previous post you mentioned you only use full power (full boost) in 5th and 6th. Where do you do that on the street? Some race tracks you will never get out of 3rd.
I may be wrong, but it suggests you do not like using the gearbox, torque is your friend and you like doing things in a straight line.
Rossi's bike only makes 240hp and lifts the front out of every corner. You gonna ride away from him also? Ya think that is boring as well as you posted earlier? 340km/h down a short circuit straight is boring?
