well, youll have to try it for yourself, but from someone who has spent 12 years on 4 strokes smallest being a 600cc sport's bike and then last year i got a nsr mc21 250 its amazing.. the bike is so light and corners really well, i was very suprised. you do have to work the bike alot harder to get your reward but its well worth it, ring its neck and let it go, thats the way to ride em. makes the ol 4's feel heavy. I still have a CBR600 to ride to work everyday but thats all its good for. I took it to the track a few weeks back (the NSR is having its heads fixed again) and the CBR is just crap!!
