The BSA S31-10 Sloper (the 31 part of its name being the year not the specific model) was a Birmingham Small Arms Company (BSA) motorcycle that was launched in 1927 and featured a saddle tank that enabled a low seating position improving the centre of gravity and handling. In 1930 the BSA Sloper gained extra chrome and a new frame with a forged steel spine. The 493cc overhead-valve mode came with twin-port cylinder heads.
