Since I am a former Hayabusa rider, I felt the Roadster to be too strangled at higher rpm's. I was more than impressed with the initial bite, but from 4000ish, it was noticeably obstructed. So I'm on my way, and I enjoy every step of the performance upgrades.
The biggest production bike in the world should be able to dominate the street in terms of power, at least most of the time.
And then ... I don't like to breathe through a blocked nose myself, so why should my Rocket?
