The Calthorpe Motor Cycle Co. was amongst the earliest makers in Birmingham and traded from 1911-1938. In the 1920s Calthorpe used Villiers as well as Blackburn and JAP engines. From 1925 onward, 350cc OHV and 500cc OHC single-cylinder models of their own manufacture were built. In 1929 they caused an industry sensation with the Ivory Calthorpe, its white tank and mudguards a departure from the then prevailing all-black colour schemes. In 1930, the Ivory was re-designed with Calthorpe’s new sloper OHV single with the oil in the crankcase. The first 350 Ivory models had an straight standing engine. The engine have a displacement of 348cc, bore 74mm / stroke 81mm.

This is a great restoration project.
