This is the only dedicated book on OK Supreme motorcycles. The OK Supreme story is extraordinary and needs to be told. At well over 26,000 words, this book includes many previously unpublished diagrams, advertisements and historic photos. Includes a brief history of the marque (OK Supreme was one of Great Britain’s first motorcycle manufacturer) and an in-depth history of the Lighthouse and Silver Cloud with features on the people who worked for OK Supreme and why OK Supreme ceased manufacture in 1946. Included is a comprehensive Pilot/Silver Cloud engine analysis and workshop manual with notes on the changes in specification and instructional photos. This book is in soft cover format and measures 210mm wide (8”) and 297mm high (11”). Of all Great Britain’s ohc singles, the deep understanding of his primary market and desire to offer them sophisticated machines to meet their aspirations makes OK Supreme, under the control of one man, extraordinary and unique. This book is written for anybody who owns and wants to tune or rebuild their latter cammy engine. Easy step by step instructions. An absolute necessity for every Silver Cloud owner.
