The unit-construction 650cc Triumph 'B' series twins were the top-of-the-range models in Triumph's range from their introduction in 1963 through to the introduction of the 750cc Trident in 1968. The model range outlived the Trident, grew to 750cc in 1973 and eventually went out of production in the late 1980s. This book gives a detailed technical analysis of the bikes, and charts the development of the range from its introduction through to its heyday in the late 1960s. It looks at the development of the range, and covers the various models produced including a restoration of probably the best model produced - a 1970 T120R Bonneville. Matthew Vale has been writing books on classic British motorcycles and cars since 2004. Now retired from his work as a Chartered IT Professional specializing in computer security, he is devoting his free time to classic car and bike restoration, writing classic motoring books and articles, and spending time with his wife and family. In the past he has run such diverse classic cars as a Triumph Spitfire Mark III, MGB, Triumph Stag, and a Lotus Elite. He also restores and rides classic bikes, including the Triumph Bonneville, Norton Commando and BSA Lightning. With a lifelong fascination for glass-fibre-bodied cars (stemming from early holiday jobs at various glass-fibre factories, and ownership of many rusty cars), he is currently carrying out a nut and bolt (and glass fibre) restoration of two Lotus Elan Plus 2s.
