Manx and Inter, and all side and overhead valve singles from 1927 to 1966. There can be question as to the status of the Manx Norton. It is the worlds firm favourite for the accolade of 'the greatest road racing motorcycle'. Surprisingly , this is the first book which details the machines development through the 'works' bikes to the production, customer versions. Nowhere else is it possible to trace each years specific modifications. We have, therefore, essential reading for each and every enthusiast who has ever heard of the revered Manx. Just as important, however, is the development story of all the other Norton singles which were current with the Manx, with or without overhead camshafts. Again we have first-time coverage of the Inter, the ohc Manx sister, and all the step-sister push-rod machines:models 18, 19, ES2, 50, 16H, Big 4 and 500T in their various guises. If it had Norton on the tank and but one barrel and piston, it's in the book. Nothing is overlooked, from TT racing to wartime mud plugging, from detailed tank lining changes to carburettor fitment. Never before has such a wealth of information been offered on Britains best loved motorcycles.
