As to head shake. My other bikes have steering stabilizers but not my 990. Tightening up my steering head bearings fixed most of the shake and wobble.

But when the tires loose their shape they will begin to wobble and shake.
Well there is plenty of knobby left on the front 606 but it is definitely cupped and there is a very visible difference in knobby height / size. So I am wondering if it is the rubber itself.
I will be swapping another set of wheels on in the next couple of days hopefully and will take a closer look at the front wheel as well of course...
I have a steering head damper and it is still noticeable at 100kmh... and just gets worse the faster you go.

I am thinking of trying out the Heidenau K60 tires though.
