I own a zx10 06, no noises yet, but two of my friends are having the same problem, with theirs at about 3000 km, I took one of them out , and it sounds like something is loose or rattling in the front end.
does it sound like a rattling metal noise. because i hear a noise on the front end of my zx6r. it could be the key for my garage rattling against the bike- but it sounds like it comes from way down in front.
Get dealer a hearing aid, most seem partially deaf to any odd noises :grin
If it's a buzzing noise check for electrical cables touching against bodywork, tend to do it on overrun when you blip the throttle. Wrap with thin foam & tape or blue tack cable to body work. Headlight & indicator cables are culprits.
Also make sure all bodywork fixings are secure.
For rattling check the brake pads have copper grease behind them.
