just like to share my experience today, i've been riding my cb250 and today had a chance to ride my mates vfr/vrf 400(forgot which it is). this bike blew me away! its the only other bike i've ridden and i was amazed at the difference. of course i expected the 400 to be much better but really its like the difference between a daihatsu charade and a porsche!! of course ALOT more power, ease of power delivery from the throttle, better brakes, feather light gear changes, ALOT less wind buffeting, confidence inspiring and a S#(*load more fun!!! plus the sound!!....awesome screamer!! strange thing is i bought the cb250 to give me more confidence and ease of riding but after jumping on the 400 i found that much easier and alot more confidence inspiring! now to sell my cb! after riding this i can start to understand why you guys all love your sports bikes.... and since this bike blew me away.......i can't even to begin to imagine what a 600 or litre bike would do!!
