The ZZR is the slightly less rabbid version. A lot of manufacturer's, including Kawi produce the same super sport from years past and give it a new name, as the newest latest and greatest super sports keeps the original "ZX" moniker.

yup, you got it right. The ZZR isn't being made currently, and is an older trend. The current trend seems to be to make a street and track bike, each engineered exclusively. I'm sure a model's success has something to do with it as well, as was the case with the R6S - the exact same YZF-R6 from a few years prior, which used to be the defining SS of it's day... I hope I'm making sense.
