Lil' and definitive update about my case, too (sure it's stil up-2-date...).
After removing for maintenance the complete front fork assembly including column and steering bearings, it appears as suspected in my last post (4 years now) that excessive wear of the column was definitely the cause of my problem.
The wearing inssue mainly comes from the ovalization of the housing of the lower bearing in the frame. Yes it is...
And after some Sherlock's investigations, it appears that it's mainly because of the bad mounting of my old top-box (too cantilevered), and also because of the fact that it was a "soft" case from GIVI and it had a sort of "wriggling" inertia that generated longitudinal vibrations as if the wheels were oval or poorly balanced, which over time (50000 kms) have completely loosened the lower bearing by enlarging its housing in the steel of the bottom of the column, and so the frame.
Tried to solve with Loctite 660 Quick Metal (welding not possible) and for now that's all I've found.
To whom it may serve before critical steel injury
