Civilian production resumed in January 1919 with three models emerging from the Sunbeam works.
The 3½ h.p. was available as a 'Sporting' model which resembled the 1914 T.T. model, and a 'Standard' model based on the War Department GS model with its heavier chains and large diameter hubs.
An 8 h.p. JAP engined v-twin, similar to the last JAP-powered military Sunbeam, was produced for heavy sidecar work.
The range for 1919 consisted of:
2¾ h.p. Standard model
2¾ h.p. Sporting model
8 h.p. (996cc) JAP V-twin model
