UMMMM, yeah i'm gonna have to go with tiny d#ck Patron on this one, go with the 600 anyone with any amount of brains knows the new 600's have plenty power and if you get bored of it, it's not the bike it's your skill you need to be working on, a liter for your first bike or even a 750 will only amplify your stupidity but hey you're grown and I know all of the people telling you to get a liter on this board obviosly started out on one themselves and that is why they are still around, or more likely they don't even own bikes and have just HEARD that 600's suck.
