I am looking to get into motorcycles. I am getting my permit very soon, so it will be about a year until I can ride alone. I know I should start small, like in the 250cc range, but I feel that this would become boring after a while. I am thinking that getting a ninja 500R or a 600cc bike would allow me to learn, and provide thrill and fun for years to come. Anybody have any expericene or feedback?
