The Triumph 3½hp was introduced by Triumph Motorcycles in 1906. It featured a 453cc single-cylinder engine and a rocking fork with horizontal springs, offering greater stability and comfort. This model also featured a Bosch-Simms high-voltage magneto. This motorcycle was notable for being highly competitive in racing and everyday commuting, consolidating Triumph's reputation as a manufacturer of innovative, sporty motorcycles in its early years. Although this model debuted with a 453cc engine, over the years underwent several technical updates. In 1908, the engine was enlarged to 476cc and in 1910 it reached 499cc. The Triumph 3½hp was produced until 1914.
