1 Chapter 1 A brief history of the company The origins of the Triumph motorcycle company go back to 1885, when a young German, Siegfried Bettmann, moved to London and started an import/export business selling pedal cycles branded with his own name. In 1886, Bettmann changed the company name to Triumph, reasoning that its meaning was self explanatory, and also because it translated well into many European languages. During 1887, Bettmann was joined by Mauritz Shulte, a young German engineer. A year later they moved to Coventry and rented a small factory with the intention of manufacturing their own machines. Bettmann and Shulte reasoned that Coventry, being the centre of the cycle industry, would be an ideal manufacturing base since it was close to suppliers and boasted a plentiful supply of skilled labour. In 1902, the company produced its first motorcycle, using a Belgian 2 1 / 4hp Minerva engine clipped to a bicycle frame. It was not long, however, before a Shulte-designed engine was built, and 1905 saw a totally in-house Triumph of 3hp (363cc) being offered for sale. By 1915, the engine capacity had increased to 550cc, and the machine now looked like a proper motorcycle (gone were the pedals of previous years). The machine was fitted with a three speed gearbox, though a belt was still used for the final drive. This motorcycle, the Model H, was supplied to despatch riders during WWI, and soon gained a reputation for quality and reliability in the mud of the Western Front. The term trusty triumph originated in this period, and the company used it when advertising the model. Triumph had experimented with a 600cc vertical twin as early as 1913, but the war halted development. This was the first known vertical twin from Triumph. Later, in 1933, a Val Page-designed 633cc vertical twin was produced. Unfortunately, being rather old fashioned in appearance, it did not win public acclaim saw the company fall into financial difficulty, like so many others during the depression of the 1930s. So serious were the problems, in fact, that the company went into bankruptcy, and closed completely in The pedal cycle part of the company was sold to Raleigh Cycles, Nottingham, and the motorcar side to the Standard Motor Company, Coventry. Most of the motorcycle manufacturing business was purchased by Mr Jack Sangster, then owner of Ariel Motors, Birmingham, for the reputed figure of 30,000. The factory and the plant were leased from a Mr Graham, the official receiver appointed by Lloyds Bank, and spares were sold on commission, thus reducing the original outlay. It didn t take long for the newly formed Triumph Engineering Company Limited to start production of motorcycles. This was largely because Sangster had sent one of his most competent Ariel men, Edward Turner, to Coventry to be General Manager and Chief Designer. This appointment was to prove inspirational, and, as we now know, the company went on to become one of Britain s most successful motorcycle firms. It wasn t long before the youthful 35 year old Edward had designed a vertical twin which would change the course of motorcycle design for the next three decades. Although the vertical twin concept was copied by most of the British manufacturers, good as they were, the Triumph stayed pre-eminent. When the first Triumph twins arrived in the USA, just prior to WWII, they were an outstanding success; taking on and beating the Indians and Harleys, which were often twice the engine capacity of the Triumph, and winning races on the speedway tracks and in hill climbs. Edward Turner, who regarded himself as chief salesman as well as designer and financial director, soon saw a potential sales outlet in the USA. To this end he had started corresponding with a Mr Bill Johnson of Pasadena, a lawyer and keen motorcyclist. This correspondence soon blossomed into a strong personal and business relationship, and, when Johnson wanted 6
