>>574630well OP, do you have a job? just work and save money. hold onto your dream. someday soon you can buy yourself the Motorcycle you want.
maybe join a local trail riding club and they can teach you how to ride. if you get to know some good MC people they might even let you use a loaner bike to learn on.
Better yet, take the MSF riders training course. They provide MCs to take the classes on and you will learn alot of good things to help you ride safe and have fun.
