My budget is going to be approx $5-6K, and I have short listed a few models to check out, the ZX9R being one of them.
My question is that I have never ridden one of these before, and before I go and test ride bikes I wanted to get some opinions of them, and what to look out for when inspecting one? Also, I guess, what are known to go wrong with these babies etc etc.
Of course I know the opinions expressed will be biased being on a Kwaka web site, but hey, it's a good place to start!

Two that have piqued my interest so far are:

Re the Streetfighter one, I know it's "different" but bikes like this have always had an appeal to me, hence I used to ride a Zed.
Anyway, have at it!!
