After the Second World War there was a booming industry in the production not only of autocycles, but also lightweight machines, as the bulk of motorcycle production was being sent for export. James produced a range of lightweight machines with engine capacities of 98cc, 125cc, and 197cc, utilising Villiers 1F, 10D, and 6E engines respectively. The 98cc version was equipped with a two speed transmission, whilst the larger capacities had three speeds. It is not know which of the three capacities NPK 789 originally carried, but it has been without its engine/gearbox unit for many years. Purchased at an indeterminate time, it is in need of restoration and sold strictly as viewed. There are no documents with this lot.
