First< Hi and

to SBN!
Secondly, there are a few things that you will find out on your first track day.
Your ZX-10R has waaayyy too much power
You will actually be able to get a feel for how much power there is in the bikes front brakes.
Only go as fast as YOU feel comfortable!
There is more grip from the stock tires than you'd think.
You can lean over waaayy more and hang off more in the corners than you thought possible.
By the end of the day, you will be completely exhausted.
Ok, I'll let everyone else chime in.
