Superb Four was a motorcycle produced in 1920. The engine was designed by W. F. Hooper.

1920 This machine was launched in November 1920, to coincide with the Olympia Motor Cycle Show. It featured in the press and there was much talk that it was to be the first British-built four-cylinder since the end of the Wilkinson TMC.

The in-line air-cooled four-cylinder 991cc engine was in-unit with the three-speed gearbox and chain final-drive. It had ohc valve operation, finned light-alloy cylinder block, fully enclosed working parts and pressure lubrication. It was also fitted with a Zenith carburettor and Lucas Magdyno for mixture, ignition and lighting respectively. The well-designed unit fitted into a purpose-built duplex frame and the whole machine was of high specification.

Only a handful were produced and the under-funded company collapsed in 1922.
