1923
SUNBEAMS

 Model Range
The model range was the same as the previous year 1922 but is supplemented by the return of a 2¾ h.p. (350cc) side-valve machine some 8 years after the original 2¾ h.p. model was dropped in 1915.

Three versions of the square-stroked 3½ h.p. model remain available, the 'Light Solo' version now inserting the 'square'-stroked engine into the sportier Longstroke frame.

Cycle parts
'Vee' rim brakes at front and rear are provided for the sporting looking 2¾ h.p. model, echoing the established 3½ h.p. sporting models, the Longstroke and Light Solo.
