Triumph Model H Model H was fitted with a 499 cc air-cooled four-stroke single-cylinder engine. It was also the first Triumph not to be fitted with pedals, so was a true motorcycle. 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. More than 30,000 Triumph Model H motorcycles had been produced
