Description
Sectioned. Made by the Villiers Engineering Company Ltd, Wolverhampton. It is an example of a highly developed two-stroke motor cycle engine produced in large numbers by a firm which had specialised in this type of engine since 1913. From 1934, Villiers engines featured directed inlet flow of fresh gas to the cylinder, in conjunction with a flat topped piston, invented by Dr Schnurle in 1928 to supersede the original deflector type of piston.
