Aubier & Dunne Engines and Motorcycles

A Brief History of the Marque

Founded by Georges Aubier and his American son-in-law John Dunne in 1921 at Saint-Amand-les-Eaux in north-western France.

These engines were used in many marques including Automoto, Beltcycle, De-De, Dresch, Drevon, Favor, Genial-Lucifer, Guiller, Hirondelle, Le Grimpeur, Liberia, Lucer, Mabec, Mandille et Roux, Motobloc, Motopedale, MR, Narcisse, New Map, Onoto, Pasquet, Pierton, Poinard, Prester, Roussey, San-Sou-Pap, Socol, Utilia, Ultima and Verlor

The firm also built aviation engines including inverted twostroke twins and triples used in light aircraft such as the Flying Flea.

Aubier & Dunne motorcycles were produced from 1926 to 1929, most of which were powered by their 175cc two-stroke, but there was also an advanced four-stroke OHC unit-construction twin produced in 1929. The firm continued to build BMA machines of 100 and 125cc. In the early thirties the Italian engineer Giuseppe Remondini joined the firm and designed a range of engines which were very well received.

John Dunne married Suzanne Aubier whilst based in France at the military base in Libourne after WWI, and after a short stay in Magnolia Illinois they returned to France.

The marque was absorbed by Automoto in the early 1950s.

    Aubier-Dunne engines
    I am attempting to produce a series of write ups for VMCC but am not much good at web etc! I can not find pictures of engines or better still an exploded view of drawings to help me make comments such as chain or gears for primary drive? Can you help?
