Triumph 350/500 Unit-Construction Twins Bible: 1957 - 1974

Peter Henshaw has had an enthusiasm for anything with wheels from an early age - from bicycles to 500hp tractors. He was the editor of Motorcycle Sport & Leisure for five years before going freelance, and now contributes to a whole range of transport magazines, including MSL, TAG, A to B and Tractor, as well as The Telegraph. He's also written over 30 books, including 10 about bikes, and is an all-year-round motorcyclist who does not own a car.
