Thanks for the advice to all.
Here's another clip I had.

Imho this cant be good. I can feel it at 50kph, immagine what oscilating forces are created at 140 kph scared.
Frequency will be too high to feel it but I guess the forces have not gone away and might even cause damage to bearings etc?
I'll show these to the dealer and see what he says.
