How to restore Honda SOHC Fours

In 1969 Honda launched a motorcycle that many consider to be the world’s first superbike. The Honda CB750 had the first mass-produced 4-cylinder inline engine, a single overhead camshaft with four carburettors, a 4-into-4 exhaust system, and came with electric start and front disc brakes as standard. This specification set the bar higher than ever before on a production motorcycle, and led to other Japanese manufacturers introducing their own 4-cylinder models.

Following the success of the original CB750, Honda went on to produce a range of motorcycles using SOHC 4-cylinder engines. All with their own characteristics, they proved to be reliable and smooth running, and even today, with the correct care, can offer reliable transport on modern roads.

Now, with some examples over 40 years old, many enthusiasts wish to restore these classic machines. This book will guide the enthusiast through a full restoration of these fine classic motorcycles.
