Gordon-Simplex Engineering Co

Gordon-Simplex was a motorcycle produced from 1921 to 1922, by the Gordon-Simplex Engineering Co of Aylesbury, Buckinghamshire and of Bournemouth in Hampshire.

The machine was fitted with a 689cc sv flat-twin Coventry-Victor engine, in-line with the frame. Attached to the engine was a Lamplugh mechanical pump that provided lubrication for it, the gearbox and the entire transmission, and all components were enclosed. A steel bonnet covered the engine and the machine was fitted with deep mudguards, wire-spoke wheels and spun-alloy discs.

The design was ultra-sleek and although illustrations were published, it is unlikely that any models left the production-line.
