What kind of riding do you do most of the time? The Bandit is a pretty good 'jack of all trades' kind of bike, that's why I got it. I like to take off on day long adventures on the weekends, but I ride it 20mi to work everyday too.
I just came off an SV650, and while the SV was fine for commuting most of the time, I wasn't happy w/ it after being in the saddle all day. Half of my commute is going 70-80mph to keep up w/ traffic and the SV's lack of wind protection was a bummer. The passenger accomodations are pretty lackluster for both the rider and passenger as well. These are the issues w/ the SV that I thought the Bandit would fix. And it did.
So.. I guess it just depends. Are you unhappy w/ anything in particular on the M50, or just ready for something different? Lots of people on this site, with lots of different riding styles, with lots of different bikes... the Bandit is just what I was looking for. Fits me and my riding style perfectly, and evidentally a lot of people on this board and other agree with me there.. YMMV.
