Pooo Yiiii, had forgot about that film put out by Dunlop years ago.
Also was remembering another little " Let go of the bars and they wobble at certain speeds' no matter what you try. I had a wobble problem with a Mez Tourance front on one of my BMWs. When I finally change out the front to a new Tourance, the wobble was gone. Later found out that a certain run of those tires caused that.
What I didn't see them addressing in the Dunlop Film was ride height adjustment. Seems like in every instance, the more load on the back caused more wobble. Why didn't they increase spring tension on the rear? Of course, back in those days, I did not know anything about suspension adjustment either. Just rode the darn things and hung on. LOL!
