Just want to say to all those people who feel the need to start on 600 or bigger, i would have too, if i didn't have cousins with bikes in europe and asia, every summer when i used to visit them, i would beg them for a ride, but they would never let me touch the bikes,especially the ss600's and busa, untill i turned 12, when one of my cousins scared me by showing how violently a bike can launch and flip over if i accidently released the clutch in 1st really fast, so i never talked about riding again, until i turned 17, i went back and got over my fear, i started with 50cc quads, then 70cc standard asian motorcycles and rode it till i could rip it on all 3 gears, then moved on to a 120cc, and let me tell you, the 120cc was fast as hell, and these are standard motorcycles you see in places like Taiwan and the sort, the pull on the bike was so hard i had to grip really hard or i would have flown off.
Anyways after i masterd that bike i went on to 250,500,600 and then 1000 for the last few years. But im going back to 600, i like the weight of 600s and their agility, plus if modded right 600's can be fast as hell.
what im trying to say is any new rider that says 250's are slow, are really noobs because they have no idea what they are talking about.
lets say i can't afford to insure a 600 this summer i might go even lower, because i'd rather ride than not, and i know even if you ride an old ninja people still do look, so the vanity is no excuse for a big new bike, nice post, read about this topic in magazines too, its the most pawned topic ever.
