1927 Sunbeam Model 9/90, 493 cc. Registration number SV 7509 (non transferrable). Frame number D1721. Engine number not found. The introduction of the Parallel Model 9 so called because of the top frame tubes was introduced in 1924. It featured overhead valves, a 3 speed gear box and flat tank. Sunbeam introduced the model as a sports roadster complete with toolkit mounted below the chain guard. There was no kick start so being fairly adept at a running start was a necessity. In 1926 saw the provision of a kick start as standard. The 1927 M9 was now a much more user-friendly machine with a kick start, a balanced front mudguard, and a rear carrier as standard. The front fork was strengthened, and adjustable damping provided. A larger front brake was fitted, but the single spring clutch was retained. A Best & Lloyd pump supplied oil for the total loss lubrication system, and the familiar end-plate type rocker box was introduced. The 1927 catalogue description mentions: "This model has been improved in many ways since last season. The engine lubrication has been simplified, the overhead rocking gear has been redesigned, giving greatly increased bearing surfaces. A luggage carrier has been added and shock absorbers incorporated in the front forks." In 1928 the cost was 75 guineas. SV is believed to be fitted with a Model 90 engine, which by the mid-1920s George Dance's development programme had moulded the overhead-valve Sunbeam into one of the most formidable racing motorcycles of the vintage era, the 500cc Model 90 in particular being a match for anything in its class by the decade's end. Acquired by our vendors father in 1998, and then registered with DVLA, it has constantly been upgraded with many of the correct 90 parts fitted. Sold with the V5C, V5 and several old MOT's.
