But those are real world numbers. Bikes are geared for their displacement, powerband, and rev range. 1st gen Busa redlines at 11,000, 05'- 06' 1000 13,500. Everything is relative. Mid part of the rev range is mid part regardless. That's why 10,000 RPM on a 600 is considered mid range. My point in the beginning of this whole thing is that an 05'- 06' GSX-R 1000 is just like a Busa in that it doesn't matter what gear, what rpm, or what speed you are travelling at, just twist your wrist and it GOES!!!
