You want guttless, ride an R6 below 7000. The FZ6 has way more torque, something like 7 more ft/lbs up to that point. FI is a little snatchy with the on/off transition compared to the R6, but still better than my main ride 94 yami gts1000 with FI. Guess I'm just used to it. The FZ6 is my wife's bike. If you like torque and power w/o reving it a lot, buy a big inch cruiser or a 1000+cc bike, 600cc fours just are not going to cut it, period. I rode a Breva 750 when I was looking for a new bike to suprise her with for her birthday. Pretty bike but really gutless, my wife's 1982 KZ440 that the FZ6 replaced was faster and quicker. Same with the FZ6, a top gear roll on on the fZ6 results in way more go than than the Breva even if you downshift on the Breva once or twice which then runs into the rev limit very quickly. In general, all inline fours are a little buzzy at some point, the fZ6 smooths out considerably with a few thousand miles on the odo. Featurewise for the price, there isn't really anything out there that can beat the FZ6, or that can beat it for flat out speed. Some people are more sensitive to vibs and if they bother you, you will have to look elsewhere. The most balanced review of the FZ6 after riding one quite a bit is in MCN, motorcycle consumer news.
