I think there is a bit about the Can-Am/Rotax racer in one of the Mick Walker books.

This stuff probably ought to be in the Oddball thread...
Even worse quality!
From Performance Bikes magazine that seems to have gone bust...
They merged with Practical Sportsbikes mag and have an inner section. They were a bit crap for the last ten years but I was buying it out of habit.
Don't you look at my accountant.
He's the only one I've got.
German TZ250 with wishbone/steered girder front end.
Few more of the Hossack TZ
Displayed at the (hipster) Bike Shed Show. Did he like everything about the Tesi, except that funny front end, or what?
I took a phone picture of someone else's magazine and somewhere along the line it's become distorted, the original looked more normal...
Espargarò-KTM front wheel bounce;
at 00:20 it gets interesting:

i cant believe the saves thee guys grind out day in day out, fricken aliens the lot of them.
i have a theory its like like riding ruts in Mx
i think some riders dont seem to get front chatter as they dont grip the bars and bike as tight?
you watch the best rider they are always loose on the bike they go with the bike a fair bit.
Given a few million dollars a few years a bevy of women and a small Labrador i could dial that out for him. If only he asked.
Not sure about the rut theory?? Front wheel will tend to track around the rut, so long as you don't get the front wheel too light and climb out of it!
But I agree you need to let the front end have its way. This looks more like a front knobby walking around on a hard, oiled, dirt track surface. Basically bouncing from knob to knob.
There is a LOT of different things happening before and around 20s. (The whole system, Bike & Rider, is a Quivering Mass, not derogatory, just an observation)
I would expect that the mechanics/technicians know enough about suspension to have the springs and damping pretty close.
Looks to me that the front tyre is oscillating on very edge of grip and side slip, producing weight transfer effects in the tyre itself, that the forks cant really monitor or keep up with.
Here's Mr. H looking for similar, in the days before HD SloMo Video.
Cheers, Daryl.
