My wife has graciously indulged my midlife crisis and agreed to my dream of having a bike and heading out west to the Grand Canyon. I have signed up for the MSF rider course. I realize in an ideal world one should start with a smaller bike and then trade up. I will have about 2 months of riding pracitice before I head out west. I am really better off with something small to start on and then discover a larger bike on one of my first trips out? I would think I would be better off dealing with the nuances of a larger bike to begin with so I am completely comfortable with it before heading out. Any thoughts or opinions?
