1921 Magnat Debon
1921 Magnat-Debon Racing 350Cc. Magnat-Debon, founded by Joseph Magnat and Louis Debon, was at first based in Lyon, France and later in Grenoble, capital of the French Alps. They made bicycles in an ultra-modern, self-contained factory from 1893 and motorcycles from 1902, both in the same black and green color-scheme, powered by both two- and four-stroke engines. The factory became part, in 1923, of the large Terrot cycle and motorcycle empire based in Dijon.
