Triumph 350 & 500 Unit Twins 1957 to 1974

Most of the many available books about Triumph motorcycles concentrate on the bigger Bonneville and Trident ranges.

It reveals what these bikes are like to live with, assesses the values, advantages and disadvantages of the different models, plus, of course explains what to look for when buying one – engine, transmission, frame, brakes, electrics, paint €¦ everything you need to know!
