The Rudge 'bitsa', built by Jean-Claude Barrois.
This bike has had a chequered life, starting out as a 1928 Soyer—a French brand that produced motorcycles between 1920 and 1935.Soyer used a variety of engines for their motorcycles, including JAP, Sturmey Archer and Chaise. This particular Soyer 07S had a JAP engine but the frame was wrecked, so Barrois built his own frame—and eventually replaced the JAP motor with the 500cc Rudge unit you see here.
