French term
guidonnage
French to English

From a report relating to a motorbike accident:
"Le phénomène de guidonnage…se traduit par un déplacement de gauche à droite du guidon, à fréquence élevée"
Is there a specific technical expression for this "phenomenon"?
TIA for any help.

wobble
"A wobble is an oscillation, or side to side shake, in the front end of a motorcycle. The cause can be from almost anywhere on the motorcycle, rider or road conditions. The problem can be found and corrected with some tests and repairs, or changes. A wobble should be corrected immediately as it can cause a serious accident and even death"

I'm not exactly sure of the difference between "wobble" and "headshake" at the moment but there is one.. let's wait for other advices

Comment: "I think that all answers proposed are possible, but I like Oddie's "wobble" best. No pun intended! It also seems to have the most hits on google (although I appreciate that this is not always proof of a great deal).
Thanks for all contributions. "

... with the pavement. Handlebar waggle, dead-reardamper floatiness, and
suspension wallowing are all happily absent. And that's what ...

following ref. talks about the bike waggling, not specifically the handlebars, but the idea seems the same:
On the first day we did the 170km of fairly straightforward hardish dirt road to Van Zylsrus and then 2OOkm along the Botswana border on the Molopo riverbed back to the hotel. It was an excellent route for testing the bikes, with a mixture of terrain.
On the fast bit the speedo ran to 160km/hr, 15km/hr slower than on tar. And it required a longish stretch of hard road to get there, with sandy bits sending the rear into the famous BMW waggle and reducing speed.
The "waggle" is what a BMW does at speed on dirt, and it involves mostly the rear wheel - it just does not follow the front but hops from side to side. This trait should be ignored by the rider. The bike, with its low engine mass, solid engineering and stable geometry, would stay upright and go mostly in the direction the rider intended it to go, safely and, believe it or not, accurately. Once the guys realised this, they became more relaxed and more confident with the throttle and lived with the waltz that gives an idescribably exhilarating high.
