Book excerpt: This is a meticulously detailed history of the Triumph Bonneville, its antecedents, how it came about, and year-by-year production changes, with detailed technical specifications and contemporary road test reports showing how the Bonneville compared with its rivals. All this is covered here, plus details on how Triumph spares producer Les Harris took over production into the late ‘80s. Unlike other Bonneville books, this one also tells you how to buy one of these iconic bikes secondhand, all the pitfalls to avoid, what to look for, and what they are really like to live with.
