1930 BSA 493cc S31-10 'Sloper' De Luxe & Graiseley Launch Sidecar
Registration no. GK 1564
Frame no. Y7 1021
Engine no. Y10 603

First introduced for the 1927 season, the influential 'Sloper' started a trend that saw many of BSA's competitors adopt inclined motors. The Sloper also 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 very smartly turned-out Sloper combination was purchased by the previous owner (a former secretary of the Vintage Sports Car Club) in the early 1990s. In 1995, Christopher Franklin, a VMCC stalwart, restored the machine to a high standard and was ridden in many events.

BSA Factory records held by the VMCC confirm the machine is of 1930 manufacture (eligible for the VMCC's Banbury Run) and is recorded as a 1931 Model S31-10 dispatched 16th October 1930 to G Lawrence Motors, London. The registration GK 1564 was issued September 1930.

Purchased by the current vendor in November 2018 we are advised, the magneto has recently been refurbished, all wiring checked and now working. Last run in July 2022, the machine is offered with an old-style buff logbook, sundry bills, current MoT, and a V5C Registration Certificate.
