some beginners jump to cbrs and r1's not because of the horsepower but because of how good they look. for example when you tell them to get a ninja 250 they don't, because its not a very attractive bike.
so from sv650s heres beginner bikes that still look cool:
2003 suzuki sv650S- i said 2003 becos it's when the fairing started to look sharper and more good looking and its a beginner bike that guys on litre bikes would respect, put a pair of lower fairings on it and it'll be lookin hot!
hyosung comet gt650r- a new competitor for the sv650s out of japan, it comes in the gt650s(half faired), gt650r(fully faired) and the gt650rl(gt650r with a horsepower restricted engine). it's also a bike that will demand respect on the road and the track. cheaper the sv but harder to find aftermarket parts for.
aprilia rs250-best looking out of all beginner bikes but more expensive, great for small statured people. but is built for the track so you need a street kit for it (turn signals and stuff). great in the twisties.
cbr f3- 90's sportbike so is cheap is not as fast as the current cbr. but still take it easy because theit is still a sportbike!
yamaha fz6- r6 engine in a lightweight package, good for tall people, underseat exhaust. good for a beginner who knows their limits on the throttle.
kawasaki ninja 650r- also new competition for the sv650s. very different from the 250 and 500. very attractive bike.
PS IF YOU SEE SOMETHING WRONG WITH THIS DON'T RANT ABOUT IT, JUST TELL ME THE PROBLEM SO THAT I CAN FIX IT.
