I assume you mean GSXR 600?

There are plenty of things you can do to modify motorcycles, but I wouldn't spend the money modifying a bike that old. I would use it as a tool to learn how to ride, then at some point if you feel you need more bike, buy a late model sportbike instead. You will never get a return on your parts investment with a bike that old, and you will end up with a bike far more expensive and still less capable than a new stock sportbike. That said, there is really nothing the new sportbikes need in terms of power. By far the best investment in modifications is sorting the suspension. Have it correctly sprung and setup for your weight and application, and that will make a night and day difference in the way the bike handles, whereas extracting a few more horsepower will make no difference whatsoever.

And no matter what you do, buy some real gear. You will appreciate it the first time you end up on the ground.
