In the early 1920s, Veloce realized that in order to grow as a company, it needed a new machine of advanced specification and developed an overhead camshaft (OHC) 350 cc engine, which became known as the 'K' series, 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, and 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 KTT, built between 1928 and 1949.
The 1929 KTT was the first production motorcycle to feature positive-stop, foot-actuated gearchange.
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 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.
