==Velocette 'K' series==
In the early 1920s Veloce realised that, in order to grow as a company, it needed a new machine of advanced specification. It therefore developed an overhead camshaft (OHC) 350&nbsp;cc engine, which became known as the 'K' series and was introduced in 1925. After a year of teething troubles with this new design, Veloce entered slightly modified 'K' models into racing events such as the Isle of Man TT and Brooklands races. The reliability and sweet running qualities of their new engine led to a long string of racing successes and the introduction of a production racing model, the [[Velocette KTT|KTT]], built between 1928 and 1949.<ref name="Mirco" /> The 1929 KTT was the first production motorcycle to feature a positive-stop, foot-actuated gearchange.<ref name="siegal thruxton" /> The roadster models developed from this initial model K were the [[Velocette KSS]] (super sports), KTS (touring sports), KTP (twin exhaust ports), KN (normal), and a few variations. A notable change in engine design was introduced in 1935, the 'KSS Mk2' with a fully enclosed aluminium cylinder head. The OHC engine series continued for roadsters until 1948, when the final KSS Mk.2 versions were produced, with rigid frames and Dowty air-sprung telescopic forks. Accurate valve timing was accomplished through the pioneering use of [[timing light|stroboscopic lamps]]. The 'K' series showed an excellent turn of speed and reliability and soon the factory developed racing models to compete in the [[Isle of Man TT]].<ref name="Mirco" />
