I'm with you! Although that R1 had alot left in it!
Topped out my GSXR-750 @ 174mph bouncing off the rev limiter.
We would do midnight runs (no traffic) on highways that were pretty straight and about the 4 lanes wides down here. Although the fastest I've witnessed was 192mph on the street (we always verified the runs by GPS, only way bragging rights would hold up). Although looking back it was quite retarded and we were just future ORGAN DONORS.
But most XS owners have them to go slow not fast. To be seen, so people can look and appreciate the love of labor that everybody puts into there ride!
