BSA  1922   “Light Six”   6 HP   770 cc side valve  V-twin  frame # T 1833  engine # 1925

The Model E was BSA’s first V-twin, primarily intended as a sidecar machine. 
It was introduced in 1920 and remained in production for about 3 years. 
In 1922 a somewhat scaled up version was brought out, the 986 cc model F. 
The  6 HP model got a lighter frame for model year 1922, hence the “Light Six”.  
This model was eminently suited for fast solo   or sidecar work. 
The vintage BSA combo provided dependable, inexpensive transport for many thousands of  families through many years of production.  
The 76×85 engine has the cylinders set at a 50 degree angle. 
The valves are interchangeable,with quickly adjustable tappets. 
The constant loss lubrication system employs a mechanical pump with an emergency hand pump.
 Primary and secondary transmission are  by chain. 
Both chains are enclosed in beautiful cast aluminium cases, with BSA’s own design of shock absorber on the engine shaft. 
Wheels are quickly detachable.   
Carburettor is AMAC, gearbox is  BSA’s own three speed design. 
This very practical vintage touring BSA  comes complete with  acetylene lighting, bulb horn and pillion seat and   has been restored  a number of  years ago.
