The 2¾ h.p. model continued and a 6 h.p. (770cc) JAP V-twin was added in June 1913. This was followed in September by a 3½ h.p. (499cc) side-valve model.
A black enamel with gold leaf pin-stripe colour scheme was introduced.
Both the 6 h.p. model and the 3½ h.p. model were fitted with a three-speed gearbox. The first model retained the single-speed configuration.
