Interesting............47 years on many junk bikes, I have never had a wobble, on unmotorised two wheels.
I weekly do 46 - 50 mph on my touring bike on some very bumpy roads and can hardly keep my hands on the bars for bumps but no wobbles despite the bike and me weighing in at a shade under 100 kgs.
Its a resonance thing which needs certain speed and frequency of bumps / steering trail with certain section tyres / weight distribution on the wheels.
Bigger section tyres increase the trail, and some will say the drag on steering which dampens out instability
