This title features an introduction by Les Williams, formerly the Triumph factory race team manager. It is a wonderful book on the amazing racing history of the 'fast but fragile' Triumph 500 unit twin. From the Daytona successes of the mid '60s to the end of the factory racers, and that amazing second place to Agostini and the mighty MV, in 1969 this book details the full history of the Triumph 500 unit twin racers. The story is told mainly through the hundreds of period photos and in the words of the main protagonists themselves - the incomparable racers Percy Tait, and Gary Nixon in the USA, the racing team including Les Williams and Arthur Jakeman for example, and also the privateers 'special' builders such as David Kirby, Rob Prior and Mick Hemmings amongst many others. This is a book full of insight into those heady days of racing success for the little 500 unit twin. It is a fascinating book which will be welcomed not just by Triumph enthusiasts but also by all those interested in motorcycle racing during the 1960s. Complete with a great many photos, and beautifully presented in colour where possible, this is a real gem.
