SUNBEAM MODEL 6 Models/Series Timeline, Specifications & Photos

The Sunbeam Longstroke was the fastest production, single cylinder, side-valve motorcycle in its day. The model stayed in production for the life of the company and the subsequent AMC take-over in late 1937. It underwent many stylistic changes; notably from flat tank to saddle tank in 1929. Known as the Model 6 prior to ICI's takeover of the company in 1929, it was marketed as 'the Lion' during the 1930s - the tank emblazoned with ICI's trademark lion emblem.
