Friend from Belgium sent me a video clip from a local ,Media Programme, but also reports about the Battle of Mons in 1914, along with this clip about the 1950 Mons Motorcycle Grand Prix, about 3.53 in there's an Aprilia in the back ground and about half a minute later it is shown in a still photo with the winner of that race.
Altogether it's well worth watching.
