From 1920 to 1934 Roaul de Rovin built motorcycles powered by Train, JAP, Velocette, Rovin and MAG engines in capacities of 98cc to 499cc, including two-strokes, ohv and sidevalve engines. He purchased the Sans-Sou-Pap motorcycle factory in 1928, and also built three-wheelers and, after 1945 with his brother Robert de Rovin, small cars. Raoul was also an aviator and a driver of Delage racing cars.
Rovin motorcycles had considerable success in competition, with 15 world records in the 75cc to 175cc classes, 8 wins in the Bol d'Or, 7 victories in the Tour de France and many more besides.
Roaul died in Paris in 1949 at the age of 53. Not a long life, but broad and deep.
