I am a fair way off getting off the 250 restriction, but am still constantly looking at bigger bikes. Dont really want much more than a 600 (as I commute 60Km & like good fuel economy), and a sports bike style, while my body still lets me. Been real keen on the Hyosung GT650R because of the look and the price and it feels good when I sit on it. Another choice is the Honda CBR600F. My ? is. . Whats the difference between the 600F and the RR.
