Following on from an advanced but unreliable twostroke that was originally designed for the TT, the company developed a powerful four-stroke with overheadcams. This classic design was the Velocette Model K and would become the blueprint for future models. It had a 348cc engine with the camshaft driven by shaft and bevels, and a narrow crankcase. This arrangement would remain a design feature for the Velocette single. The success at the TT the previous brought such a demand for Velocette motorcycles that the firm moved to Birmingham where they had bigger premises. The model U had taken over from all the rest and was the only one in production. Sports and economy versions of this model were also available. The success of the older model K had inspired the arrival of the sports KSS - this had narrow mudgards, a larger fuel tank and a tuned engine. Following on from this came the KS - this combined the KSS style with the cheaper K engine. More specs and user manual of Velocette you can see in next overview.
