Classic Motorcycles & Velocette The Three Twins: Roarer, Model O and LE 2 Book Set

The book is the fruit of hands-on experience gained in the workshop as well as knowledge gleaned over years of consulting books, manufacturers’ manuals and specialist magazines by one of the leading technical journalists in the sector, Massimo Clarke. It is intended as an easy-to-read guide with clear, precise contents regarding the restoration of classic bikes, with attention being focused not on pre-war models but those from the 1960s and '70s, those on which we still work most frequently today.

All aspects of restoration are dealt with special reference to mechanical work on the engines and the chassis components, those which enthusiasts can do themselves in their own garages, using tools that are easy to find at reasonable costs. The book is enhanced by an in-depth examination of the reassembly of the crankcase and two chapters dedicated to the final drive and the spark plugs. A guide of fundamental importance for those who want to “get their hands dirty” around their classic bikes.

An in-depth engineering analysis of the twin-cylinder motorcycles produced by Veloce Ltd: the Roarer, the Model O and the LE. The book looks at the design features that are common to all three twins, as well as the design influences of the LE. Although development of the LE was flawed, the honesty and ingenuity of the design is duly recognised.

The Veloce company is well regarded for producing some of the best single-cylinder motorcycles in race form and for private use. It is not so well known that Veloce Ltd also produced some twin-cylinder machines: the Roarer, for racing, and the Model O for production. These bikes had many engineering features in common, such as twin contra-rotating crankshafts, inline cranks, shaft drive, and swing arm rear suspension. The supercharged Roarer was never raced because of the advent of war; this also put paid to the development of the Model O, which would have been the first so-called ‘Superbike.’

After the war, the Goodman family, which owned Veloce Ltd, focused on the production of a ‘Motorcycle for Everyman’: an idea that had featured in the company’s production bikes since its formation. Ideas embodied in the Roarer and the Model O were drawn on to produce the twin-cylinder LE range of motorcycles; these, however, were not well received by the motorcycling public, and many blame the production of the LE for the eventual demise of the company.

The purpose of the book is to present, from an engineering perspective, an analysis of the Roarer and the Model O, comparing and contrasting the methods adopted by their designers to meet the different design specifications of these bikes, and to illustrate how the ideas developed in this exercise appeared in the LE range of motorcycles.

The authors, Brian Agnew and Ivan Rhodes, met in the 1960s when Brian worked at Rolls-Royce Derby. They spent their weekends tinkering with motorcycles, and both have an intimate knowledge of the Velocette twins both from their time spent together and from their personal projects.
