EVERYTHING. Too expensive in cost, maintainance, repairs, insurance, gas etc... When you crash it (which you will) YOU WILL CRY. Honestly sport bikes are hard for begginers period because they are high off the ground and heavy, you'd be best served buying a used honda rebel for $1000, riding it for 6 months and upgrading, I know they're kinda lame but there's a reason a lot of MSF classes use them, they are SUPER lightweight, comfy, and also easy to ride and maintain, then test ride different bikes and get what feels best to you.
