My Zx-9 had a Hindle pipe, lowered, 15 tooth front sprocket, and dynojet jet kit. Best was 9.79 @ 140mph. Most bike will go 9s. The only ones that can't are 600s and they are pretty close now, i.e, record is 10.07 in 600SS. R1s are a little faster than ZX-9s in my opinion, I had one that went 9.74 @ 142mph. I never ran my busa with a stock pipe to answer your other question.
