It would appear that Motavia was a Gnome-Rhone company which marketed a number of machines from other manufacturers, as well as rebadged versions of their own motorcycles.
Motavia marketed the Gnome & Rhone R4f as type 9tv.
They sold Automoto Villiers 100cc VML machines as a Motavia 2tv, and offered a rebadged Follis cyclomoteur along with several other Lavalette-powered machines.
