Brief History of the Marque: Roc
Financed by the aclaimed author Arthur Conan Doyle, Roc motorcycles
were built in Guildford and later Birmingham to the design of A.W. Wall.
The machines used both Precision and Roc engines of 2 to 6 hp, mostly V
twins. Wall's designs included three wheelers and bicycle engines. Production
ceased soon after the onset of the Great War.
