Continuously developed, the innovative Velocette two-strokes had proved reliable, economical and very popular, but by the early 1920s it had become apparent that a more upmarket model was required. Other manufacturers were fielding new overhead-valve and overhead-camshaft machines, and Veloce Ltd followed suit, the Percy Goodman-designed, overhead-cam Model K first appearing in 1924. Of 348cc, the new engine employed a single overhead camshaft driven by vertical shaft, and was unusual in having a very narrow crankcase, an arrangement determined by the existing transmission and frame design, which made for a stiff crankshaft assembly. Entered in the 1925 Isle of Man TT, the new model K did not fare well, all three entries retiring because of lubrication problems. Its engine redesigned to incorporate dry-sump oiling, the ‘cammy’ Velo returned the following year to score a memorable victory, Alec Bennett romping home in the Junior race 10 minutes ahead of the second-place rider! Second place in 1927 followed by another win for Bennett in 1928 ensured a healthy demand for Velocette’s overhead-cam roadsters and prompted the launch of the KTT, one of the most successful over-the-counter racers of all time. By the end of the 1920s, Veloce’s range of K-Series roadsters boasted a host of variations on the theme that included Normal, Sports, Super Sports, Touring, Economy and twin-port models. This K-Series Velocette incorporates the cycle parts of an early-1930s roadster, a KTT competition engine of similar vintage and a four-speed, positive-stop, road-going (kickstart equipped) gearbox of the type introduced in 1934. Fully restored in 2001 and running since then, it is presented in apparently excellent condition and offered with Swansea V5 registration document.
