Gradior Machine

Gradior motorcycles were produced by Gradior Machine of Stafford in 1911.

This make was only listed for one year and was fitted with a 3½ hp JAP single-cylinder engine with a two-speed countershaft gearbox, chain transmission, leading link forks and an ASL air spring for the saddle. A larger engine was available for sidecar work.


A new machine for the 1912 market is the Gradior, the production of the Gradior Machine Co , Stafford. This machine derives its power from a 3½ h.p. J. A. P. engine, and has a plate clutch on the engine-shaft operated from the handle-bar by Bowden wire. Transmission is by Renold chain... The seat pillar, as will be noticed, is supported on an A.S.L. air spring.
