I got my yellow 600rr in October last year. I love the bike, but I was thinking of going for something bigger. My stock 600rr hangs with 900's easy!! This makes it hard for me to drop extra coin on a bigger bike when all I feel I'm gaining is straight away speed. It just seems to me that a bigger bike is only good for a better top speed. What are the other differences? Is getting a bigger bike worth it, or should I just stick with my 600rr and mod it out?
