1935 BSA 493cc Model M35-10 'Sloper' & Noxal LC Special Sidecar
Registration no. XAS 535
Frame no. E10 220
Engine no. E10 297

Introduced for the 1927 season, the influential 'Sloper' started a trend which saw many of BSA's competitors adopt motors with inclined cylinders. In addition, the 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 Sloper motorcycle combination was rebuilt over an 18-year period by the current vendor, an award-winning restorer of classic motorcycles at local, regional and national levels. Completed in 2005, the BSA is only being sold to create space for other projects. Described as in generally good condition, the machine has not been run recently but passed its MoT at the last time of submission three years ago. Only relatively mild re-commissioning should be required before it returns to the road. Accompanying paperwork consists of a VMCC dating certificate, V5C registration document, and a Noxal range brochure.
