600's have crap power down low.
Do you have any idea what torque is? Apparently not. You don't have any.
My bike is making almost 3x the amount of torque from about 2000RPM compared to your R6. I love not having to downshift when I need to pass a car on the freeway. Torque = Fun which is what an R6 does not have. The dyno proves it. My bike? A nice fat torque line all the way from the bottom to the top. F'n love it!!!! Keep the 600's on the track where they belong.
Ah well, if you like to rev the piss out of that thing to get it to go, I guess that's all that matters. I like all bikes but I know which ones are more fun. You haven't got to that level yet. All in due time son.
