Hold up let me get this straight. You have no clue about bikes and want to start on a zx9? You are just asking for trouble/ insurance will rape you.
Get some insurance quotes before continuing with anything! There are many bikes out there for less than $3k, look for 250, 400, 500, 600, 650cc bikes.

Great bikes but none of which are for me, I may not know much about buying a used bike but I've ridden big ones and a smaller bike will just be a waste of my time/money.
