Sunbeam 1938 493 cc OHV “Light Solo Sports” frame# 2214 engine# A26/2/240
In the mid-thirties Sunbeam parent company ICI (Imperial Chemical Industries) decided to dispose of the hardly profitable cycle and motorcycle side.
AMC bought the business in 1937, their main interests being the bicycle dealer network and the well-establish famous “Sunbeam” name. Production moved from Wolverhampton to Plumstead.
The range consisted of OHV models in capacities of 250, 350, 500 and 600 cc machines and 500 and 600 cc side valve models.
The OHV machines were exceptionally quiet because of the ingenious spring loaded cam pinion.
In this construction the cam pinion is built into two parts with the teeth held slightly out of phase by a spring, which compensates for any backlash.
This “Light Solo Sports” is in fact a sports version of the famous Model 9 with a high performance engine, 3.00 x 21 front tyre and sports mudguards.
Engine compression of the Light Solo Sports is 7 to 1, the Model 9 has a lower compression of 6.5 to 1.
Petrol consumption according to catalogue is 75/80 miles per gallon, oil consumption amounts to 2,500 mpg.
This well restored fine Sunbeam has a 4 speed Burman gearbox with foot control
