If u have 0 expierence on a motorcycle i wouldint recomend getting ne of the new 600's, 1.because you'll most likely drop it, and it costs a shitload to replace parts. 2. the new 600's have way too much power for a n00b. The late 90's cbr's would be good, and yeah the katana has about the power you want on a starter bike, but it weighs an assload. I started on an EX500 (Ninja 500R) and i would deff recomend that to neone who hasint ridden before. Has plenty of power to keep you happy for at least a season, and you can pick one up pretty damn cheap, ive seen late mid to late 90's with only a few thousand miles on em for around $2500. Just my 2 cents, ive watched to many guys who dont know what their doing buy brand new 600's because they think their not that powerful and fuck themselves up on em, have fun, wear ur gear, and be careful!
