1930 BSA 499cc S30-13 Deluxe Motorcycle Combination
Registration no. DX 8675
Frame no. XH12225
Engine no. XP.3341.

During the 1930s its advertising slogan - 'One in Four is a BSA' - reflected the Birmingham-based company's status as the world's largest motorcycle manufacturer. In 1927 BSA had introduced the influential 'Sloper' (so called because its inclined cylinder) thereby starting a trend that saw many of its rivals launch similar machines. Nevertheless, models with vertical cylinders continued to form part of BSA's extensive range, outliving the Sloper when the fashion for inclined cylinders faded. The '27 Sloper featured a trend-setting saddle tank that afforded a low seating position, and for 1930 gained chromium-plated brightwork and a new frame with forged steel spine. Models with the 493cc overhead-valve engine came with twin-port cylinder heads. For 1930 the Birmingham firm offered no fewer than 18 models, six of which had inclined engines. The Sloper range remained essentially Vintage in character until its demise in 1935, by which time the line-up had shrunk to just two models: one overhead-valve, the other sidevalve, both of 595cc.

This overhead-valve BSA Sloper is attached to an attractive Swallow sports 'chair'. Issued in 1964, the accompanying RF60 continuation logbook lists the late private owner as registered keeper from September 1975, followed by his wife. The machine also comes with an old-style V5. No previous history in known. The combination will need recommissioning before returning to the road and thus is sold strictly as viewed (the engine turns over).
