A motorcycle is a vehicle of change, after all. It puts the wheels beneath a midlife crisis, or a coming-of-age saga, or even just the discovery of something new, something you didn't realize was there. It provides the means to cross over, to transition, or to revitalize; motorcycles are self-discovery's favorite vehicle.
