BSA S31 Sloper
The BSA S31 Sloper is a British 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. The Sloper range remained much the same until its demise in 1935, when there were only two models, an overhead-valve and a sidevalve, both 595cc.
