OMC was a motorcycle produced in 1930, at the SOS works at Hallow, near Worcester.
This was a lightweight machine built at the works run by Len Vale-Onslow and marketed by his brother. It had a 172cc Villiers engine and three-speed Burman gearbox that were fitted into a pin-jointed frame with Webb girder forks. The result was a stylish machine that was neat and well-finished.
Few were built and the name was soon gone.
