In TFA there is a photo of Pirsig and his son on their motorcycle taken by Sylvia Sutherland, with this legend: "Robert Pirsig’s Zen and the Art of Motorcycle Maintenance is a novelized account of a real road trip he took in 1968 with his troubled 11-year-old son Chris. Over the course of a month, they traveled 5,700 miles from Twin Cities, Minnesota, to San Francisco and back. His motorcycle was a 1966 Honda CB77F Super Hawk, Honda’s first sport bike. The model’s speed, power, and reliability made it a standard-setter for modern motorcycles."
