"La marque qui s'impose par ses qualites, par ses prix" (The brand that stands out for its qualities, for its prices).

Founded by Marc Martin in 1926, the Vincennes factory's first model was a 175cc single. This basic model remained in production, with minor developements, for over a decade. In 1927 it was joined by a 250cc three-speed dual exhaust model and 1929 saw the introduction of a 500cc JAP model with Staub gearbox. This model was short-lived due to the financial crisis.

Shortly thereafter a similar model with a Chaise OHC 500 engine was introduced, the Type O. It was a handsome machine but tipped the scales at 145kg and apparently lacked performance, despite being advertised as capable of 115 km/h.

The Chaise 500 was a unit-construction OHC 490cc (87.7 x 85 mm) with dual exhaust ports, wet sump and three-speed gearbox. A beautiful engine, but it weighed over 50kg.
