a few minutes = comfy?
another thing to consider... you ever plan on carrying a passenger? i really don't think leisa would want to sit on the back of that thing for more than 2 minutes before telling you to turn around. for the type of riding you seem to plan on getting into, you'd be far better off with something more like a honda VFR or suzuki SV, maybe even a kawi Z750 or yamaha fzr600. sporty enough to keep up with the sportbikes, but comfy enough to ride all the time.
