Bsa 500 650cc Unit Twins

Sometimes living under the shadow of the flashier, high-profile Triumph Twins, the equivalent BSAs were just as numerous and were exported all over the world. BSA was often seen as a less glamourous marque than Triumph or Norton, associated more with commuting and sidecars than coffee bar cowboys, but that doesn't detract from the collectibility of its models today, as the bikes have become highly usable, enjoyable classics. Unlike the many marque histories available, this book is a practical guide to buying one of these bikes. It covers the complete range, from the very first 1946 500cc A7 to the final 1973 650cc A65s. Chapters include what to look for (10min and 30min evaluations); spares prices; guides to auctions and paperwork; lists of useful contacts in the BSA community; and just as important, consideration of whether it’s the right bike for you. One hundred colour photos, useful appendices and expert advice mean this book could save you thousands.

The BSA 500 and 650cc Unit Twins were the top-of-the-range models for BSA from the early 1960s through to the Rocket 3 of 1969. The model range covered every angle, from staid tourer, through off-road racers through to true-road burners. This book has two parts - the first describes the design and development of the range from its inception in 1962 to the final demise of BSA in 1973, detailing the various models produced each year. The second part of the book looks at the practicalities of restoring and running the model, through documenting both owners' experiences and a full restoration of a typical bike. The illustrated record of the restoration of a 1965 Lightning identifies the pitfalls that will confront the restorer and the practical modifications that can be made to provide a reliable mount for today's traffic conditions.
