I had seen it claimed (on a non-FZ forum) that the FZ6R's added low- and mid-range power made up for it's lack of top-end. That the "area under the curve" was equal or better on the FZ6R vs the FZ6. Seemed plausible. But nowhere could I find a dyno chart comparing the two bikes directly. Maybe it's buried in the archives somewhere here.
In any case, I decided to put together my own comparison. I analyzed dyno charts of the 09 FZ6R (.pdf) and the 04 FZ6 (.pdf) published by Motorcycle Consumer News.
Now I understand the number of variables that affect a dyno chart's accuracy.. so I won't claim these dynos are comparable with absolute precision. But since the peak outputs of ~65hp and ~85hp are pretty well agreed upon, I think this comparison is meaningful. And here it is:
The FZ6R definitely holds a slight advantage at low RPMs---perhaps as much as 5hp around 2000 RPM but tapering off by 4000 RPM. And where the FZ6 dips between 5500 and 7200 RPM the FZ6R stays linear. But without a doubt, the FZ6 has more area under the curve---unless you never rev it above 10K RPM... but why wouldn't you? An extra 5hp on the low end and in the middle is nice, sure. But in my mind the retune is defnitely a detune.
I realize this topic has been beaten to death. But I wanted to at least post this chart here to clear up some of the confusion and misinformation out there. I'm posting this over on FZ6R-Forum, too.
Any thoughts?
