I am a newish rider and currently on my L's - (hopefully) soon to be on my p's. I have a 250 which I'm currently very happy with and don't see myself wanting anything faster for some time yet. However, I like to look at other bikes and imagine what I'd get when I upgrade up. I decided that I wouldn't want anything over the top and thought a 600cc sports/tourer bike would be a perfect size. But when I tell people of my ideas about 600cc's being a good size they keep telling me that it's too fast etc etc and a 250 is all anyone ever needs. I just don't see that a 250 would comfortably cruise at high (legal) speeds for extended periods of time on, and feel that they're being a bit patronising. What are all your thoughts? A 600cc sports/tourer isn't ridiculously too much is it after several years of experience?
