In the 1936 model range two distinct groups of single-cylinder models were introduced, the “Clubman” range for the sportsmen and the “Tourist” range for the less hurried enthusiasts.
There were no less than four 500cc Clubman models, all with twin port engine and hairpin valve springs.
The fastest model was the “Super Clubman”: it had a specially tuned engine with high compression piston, 14 mm spark plug and specially polished components such as flywheels, conrods and ports.
The compression ratio was 7.5:1 and the top speed was 90 mph.
