Everyone seems to be telling me that a 600 is huge for a first bike, but I had one very experienced rider tell me that I should get the biggest [CC] bike I possibly can for my first because I will grow tired of a smaller bike within a week. As long as I am responsible with the throttle, there should be no problem. He also added to practice on a smaller one though before actually riding the bigger one. I'm going to get a sports bike by the way. Any thoughts on this?
