It only happens on some road surfaces (rough) when very heavy braking. When it happened the other day and looking down on it, it just appeared to be flexing back and forth.
Was all right at snetterton, but then the surface is smooth.
Was wondering about steering head bearings or warped discs.
Was hoping someone else might have had the same issue and knows what needs doing. Not too comfortable with my local dealer
always full of excuses why the job takes forever and he does not have the parts.
