A Brief History of the Marque
Ackland produced motorcycles from about 1919 to 1924.
The machine was built by William Ackland who was one of the many who went into motorcycle production after World War I. He used similar components to many other manufacturers of the era, but instead of the usual Villiers engines, he used JAP V-twins.
An Ackland motorcycle in a Southampton Museum which dates from 1922 has a 680cc V twin JAP engine and 3 speed Sturmey Archer box. It is believed to be the sole survivor.
