Whilst Triumph were not amongst the earliest makers of motorcycles, they formed part of what might be considered the second wave, announcing their Minerva-engined machine in 1902. With 2 ¼ Horsepower, direct belt drive, and stirrup brake, it was very similar to many other bicycle-derived machines of the period. As large-scale producers of bicycles, it was a natural step, as was the adoption of an in-house engine by 1905, after the use of J.A.P. and Fafnir engines. The Triumph 3hp engine featured mechanically-operated valves and by 1906 a sprung front fork. Power increased to 3½hp in 1906 and a free-engine rear hub appeared in 1910. 4hp models started in 1914 and the Model H arrived with a 3 speed Sturmey Archer gearbox in 1915. After the Great War, the range for 1920 was announced, featuring the new, top of the range SD model with its cush drive 'Spring Device' within the clutch and new Triumph-made gearbox, alongside the Model H and economy model LW. 335960 is listed in the VMCC Register of Machines under no. 629, with associated registration 'TC 6613', although this number does not appear on the HPI database. Purchased by the vendor in its present condition, needing some finishing, approximately 17 years ago, no further work has been done, and he reports that the engine turns over freely with some compression and the gears select. Sold strictly as viewed, there are no documents with this machine.
