I've had my new 2K3 GSX-R 1000 for about 3 months now and in my opinion, it's the best thing out there. Previously, I owned a TL1000R and a RF900 and this makes them look like child's bikes. Because of the ultimate power that lies in the engine, this is definitely not for the new rider. I would recommend it to the experienced motorcyclist.
It is a beast just waiting for someone to roll on the throttle and I can't wait to see what this puppy can really do. So far, I have added a Hindle pipe and a K&N air filter. I am looking at the Yosh EMS box or the Power Commander as my next addition.
