Motorcyclist is a motorcycling magazine in the United States. The magazine is headquartered in Irvine, California and is published by Bonnier. The former editor in chief, Brian Catterson, had been the executive editor at the rival Cycle World. The current editor is Marc Cook, a veteran of several motorcycle publications, including Motorcyclist. Motorcyclist was sold by Motorcycle Hall of Famer Bill Bagnall (also its editor for 20 years) to Petersen Publishing in 1972. It is now owned by Bonnier, who acquired it from Source Interlink Media in 2013.
