It's the same bike that was released as ZX-6R back in 2000, which was indeed a race rep, though not much sensationalized as the other three for the lack of track prowess. It will do wheelie on throttle, the mid-range is up to par with 2003 R6, because back in its day, it was the torquiest 600 cc, a real sleeper. The top end wasn't quite as powerful as the other three, but this is all relative. The midrange of that bike is good enough to flip if the rider doesn't have sensitive throttle control. Anyway... it's considered sport tourer now just like F4i or YZF600R, only because the RR these days provide much sharper track package. That doesn't mean the ZZR or 600R or F4i is short on power.
