Sunbeam 1926 M5 500cc 1 cyl sv



Sunbeam    1926  499 cc side valve  “Light Solo”  Model 5   frame# S 09285   engine# 294/16571/6

Although vintage Sunbeam side valve machines look very much the same to many people, there were actually three different  500cc models; the standard 85×88 machine was marketed as an all purpose machine and was suitable for sidecar work. 
The “light Solo” had the same engine dimensions but sports handlebars and footrests instead of footboards. 
The reciprocating engine parts were lighter than those of the standard model, giving more power to the engine. “ A favourite choice of the clubman” as the catalogue puts it.
For the real speed lover there was the “Longstroke,”, with engine dimensions of 79×105.5 mm.
This practical example of the famous make has internal expanding brakes and mechanical oiling, both introduced for the 1925 season. 
Of course the chains are enclosed in the gentlemanlike Sunbeam manner. 
This machine has full acetylene lighting and is well restored.
