if i could do it again, id start with a SV650... if you get like a 00 or 01 jiggy 600, you'll be fine, but after getting a 1000, i now understand why they say start smaller then 600.

just get a lil 500 to putt putt around on man, u can prolly pick one up for under $2500 and ride it around till you feel good, when you get bored, start hitting the twisties with some big guys, your gonna get smoked on every straight but if your a fast learner and are learning the right things you'll be right on em in the corners and braking, like move mofo... then get left again.. when u get to that stage, start shopping for a 600.

If you dont want to do that, start with a SV650...
But most MOST importantly... please, and i say please, get some proper gear... full fingered leather gloves, a good lid, that isnt 10 years old, a jacket, leather preferably, but u prolly wont.. and some dedicated riding boots, not vans, fuk that, "i cant feel the shifter bs" i ride in $300 race boot everytime, its bs... be safe be smart, take your time and dont rush it, it'll come to you... if you rush it, you'll only fall sooner and harder.
