In 1969 The Honda Motor Company launched a motorcycle that many consider to be the world Äôs first super bike. The Honda CB750 had the first mass produced 4 cylinder inline engine, a Single overhead camshaft with 4 carburettors, a 4 into 4 exhaust system and came with electric start and front disk brakes as standard. This specification set the bar higher than had been seen before on a production motorcycle and lead to the other Japanese motorcycle manufacturers introducing their own 4 cylinder motorcycles, albeit some time later. Following the success for the original CB750 Honda went on to produce a range of motorcycles using SOHC 4 cylinder engines. All with their own characteristic they proved to be reliable and smooth running and even today can offer real reliable transport on modern roads if restored correctly. Now with some examples over 40yrs old many enthusiasts wish to restore these classic machines. This book has been written to guide the enthusiast through his or her restoration of these fine classic motorcycles.
