Jean David was joined by Montélimard and Matrat to form the company which produced Moto-Monté.
The company introduced the Styl'son brand, and for some years the two marques co-existed, with Moto-Monte concentrating on the smaller capacity machines, those from 175cc to 350cc. Their 250cc and 350cc engines were from Chaise.
They also used the name "Styl'ett", and in some cases the advertising for the two marques were all but identical, differing only in the brand name.
The Moto-Monte name was dropped in the early 1930s.
