KZ's have a really distinct sound, almost like an S2k with ITB's. That CBR650 sounds more like the early carbureted R1's or the Katana 1100.I haven't really been looking at new bikes lately but I was browsing a little while ago and noticed the new cbr650f and realized it's kinda badass. :lol:
The sound kinda reminds me of the 70s/80s honda's and kawasaki's like the kz1000 and the cb's

All in all it looks like a cool bike for $8500, much better than the ninja 650r.
