I took out the R6 for a little bit tonight after work. I'm used to my R1...I'll say that first. The R6 is stock everything practically. My R1 has slip-on microns, y-pipe, k/n air filter, and a pcIII. The word on the street about the 2005 R1 is that it is kinda sluggish between the 4k-7k RPM mark. I kinda agree with that. Well, let me just say this...my 2006 R6 has NOTHING below 6k RPM. After 6k...especially 8k...it wants to take off. It's pretty fun to ride. The brakes don't seem as good as my R1's either. Anyway, I'm pretty happy with it. Hopefully with some exhaust mods, pcIII, air filter and a dyno tune day...that sluggish 6k RPM area is gone. With that being said...I don't plan on keeping it under 6k RPM very much. Any other R6 riders agree with this sluggish low range?
