The bike is great, it has a few first year design issues, but other than that is has ran great and is fun to ride. I was just a little disapointed when my little brother blew by me on his '97 gsxr 600. I didn't buy it to race and didn't expect it to keep up with the 1000's but a bit more power wouldn't hurt. I have checked into exhausts, air cleaner and computer but all I can find is the factory stuff. It is probably good stuff, but usually someone will make something a little better at a lower cost.
