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 :eek:

Not sure if I am understanding this correctly, are you saying the bearing races no longer fit tightly into the frame like they do for everyone else ? I have never heard of this happening before and have no idea how an issue as serious as that could be fixed ! Maybe if you posted some pictures of the bearings and the hole that the races are supposed to fit tightly in that might help to show what actually is going on.

What really happened is just what I saw and what I said, and too late for pics because the whole front of my bike is already reassembled, sry :confused:
Just bad top box mounting caused the frame to wear in the bottom bearing housing, no other culprit I swear !!! :rolleyes:

Mine is a S10 model 2020 front clicking since new (1000 miles now), usual suspects checked (brake pads, fairing, windhield, etc), FINAL problem found to be over torque on suspension tube holder/brackets from factory/CKD reassembly. To fix it used previous receipe in this thread: front wheel of ground, loosen the 6 screws that hold the front suspention tube in place, shaked the hole set right/left/right severeal times to remove tensions, turned both suspensions tube a mili-notch outward, screw everything back to proper torque (26Nm top, 20 Nm bottom) firt both top screws, new shake and kicking left/right on front wheel, then middle screws both sides, mo then bottom screws. Clicking is gone for good !!!!
