Registration no. VMN 430 (see text)
Engine no. KTT 4
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 frame of a 1929 KSS, a KTT competition engine of similar vintage and a four-speed, positive-stop, road-going (kickstart-equipped) gearbox of the type introduced in 1934. Restored in 2001, the machine was purchased by the present owner at Bonhams' Stafford Sale in April 2007 (Lot 458) and since acquisition has benefited from a rebuilt engine, which received a new piston, valves and valve guides, while the oil pump was replaced. Other noteworthy features include a fully refurbished gearbox, overhauled magneto, and rear hub with integral sprocket newly fitted. A set of new MkIV valve springs are included in the sale. Described as in generally good/very good condition, the machine is currently taxed and comes with Isle of Man registration papers. Its previous UK registration was 'SV 5809'.
