That makes this bike close to 200hp at the crankshaft, and over 100ft/lbs of torque from 3800 to 10,000 rpm. It is a freaking missile, and I rarely ever find myself going anywhere near full throttle.

It's amazing how much power you can get just from tuning the ECU. I'm sure most bikes are tuned just like cars and trucks. They are tuned for the worst gas out there and detuned even more. I've retuned many stock cars and trucks and it's like night and day after I get finished. Good example was I took my brothers stock Chevy pick up at the track. He made a couple of runs on stock tune and we logged it. From that log I retuned it for 87 octane gas and he picked up a whole second I a quarter mile. A little fine tuning and picked up another half second. That's probably a 60+ HP gain.
