SMS was a motorcycle made by them in 1914. It had an unusual 2¼ hp two-stroke engine that combined the normal three ports with an automatic crankcase inlet shaped as a metal disc that acted as a reed valve under the crankcase depression. The carburettor was carried by the disc cover. Ignition was by a rear-mounted, gear-driven magneto, and there was a pedal to kick-start the engine. Gearing drove the clutch and the drive to the rear wheel was by fully enclosed chain. The neatly designed frame was fitted with Druid forks. Nothing further came of the design.
