The Triumph Model H (also known as the 'Type H' and 'the Trusty') is a British
More than 30,000 Triumph Model H motorcycles had been produced by the end of the war in 1918. The Triumph Engineering Co Ltd had been using the advertising slogan ''Trusty Triumph'' since 1910 and the Model H became known as 'The Trusty' as it proved reliable in wartime conditions, despite a weakness in the front fork spring. This was prone to break on rough ground, so despatch riders would strap a leather belt around it as a precaution. After the war, the motorcycle didn't have enough speed for racing, which was one of the principal markets for motorcycles at the time, so Triumph moved on to a motorcycle designed by Harry Ricardo, known as the Model R Roadster. When the Model H was discontinued in 1923 a total of 57,000 had been produced.

Engine differences from the previous Model A included a single cam wheel with two cams replacing separate cam wheels for the inlet and exhaust valve, and new design of cylinder casting. Valve head diameter was enlarged and the valves were spaced further apart. The Model H was fitted with a Sturmey-Archer three-speed countershaft gearbox operated by a hand gear change lever.
