The Velocette Valiant was first unveiled at the Motorcycle Show at Earl's Court in 1956. The 192cc engine was similar to that which had powered the company's innovative LE200 model, although it now had overhead valves and was air-cooled. Although the Valiant was well-constructed, it was expensive, and was regarded as providing inadequate performance due to the small size of the engine.
