Triumph 1915-1926, Model H and TT Roadster Model D The Model H was a big step forward for Triumph. The 1914 4hp model had paved the way and shown that the extra power available required the introduction of a proper gearbox to replace what was previously really only a souped up cycle hub. With the addition of the gearbox the whole frame was also made much more substantial than previous models. I think it would be fair to say that with the Model H Triumph motor cycles came of age.
