Motorcyclists feel a kinship with fellow riders that is not easily explained, but runs deeper than choices like bike brand or riding focus. A long-time rider himself, Henry Von Wartenberg has photographed motorcycle aficionados in such countries as Austria, Canada, China, France, Mongolia, Mexico, Italy, Iceland, Peru, Spain, the United States, England, and Thailand. The dozens of striking photographs here are complemented by reflections on the amazing breadth of the motorcycling world.
