for your first bike go buy a $500 to $2000 bike to scoot around on for at least 6 months, then when you are a decent rider, upgrade. and even then you wont be ready for a brand new 600 and will crash it. be sure to always gear up and prepare.

You cant go wrong with these bikes nowadays, pick which style you like best and go with it, you wont notice a 5 horse difference.
