Yeah, but what kind of roll-on performance in top gear at 65 mph does that 600 have? Pathetic, that's what. You'll need to downshift once or twice to get decent pull out of 600 sport bike.
Me, I like bikes that go both ways - good torque down low and HP up top. The Kawasaki ZRX1100 is a good example of this - it'll pull cleanly and strongly from 2000 rpm, and ends up making over 110 HP at the rear wheel.
The only Harley big-twin type motors that make over 100 RWHP are oversized (100+ c.i.) heavily tuned monsters that most people would not consider a pleasant riding experience.
I'll start by letting you know the more you talk about horsepower instead of torque the more it shows that you are really just blowing your own horn and just hoping someone will believe ya.
