I wouldnt ride a liter bike w/o one, especially on the track. You cant go wrong having one, but u may not need one, all depends on how hard u push and if u feel your bike tends to headshake under hard acceleration. :shrug
I never raced my ZX9, but I am a racer and I had it to the track a few times. That bike doesn't need a steering damper unless you are using the thing at 10/10ths level. It's perfecly stable without one and I never once experienced any headshake with it. My opinion? Save your money if it's just a street/track day bike.
My ZX10 on the other hand was another story....impossible to ride safely until I put one on it. It would headshake at every opportunity. so I forked out WAY too much money and put an Ohlins on it. Problem solved.
