The torque reaction on the shoe carrier plate
(can't remember the proper name for it)

Backplate?

That's it!


I don't know about modern anti dive systems, is there some cleverness?

All the active suspension and electronics.

The only passive effect I can see with a telescopic fork is that the
torque reaction will increases the loads on the plain bearings.

On my GPZ550 it has hydraulic anti-dive. When you operate the front
brake it actions a piston in a bypass valve on the fork legs that
prevents the damper oil going past the damper itself and so stops the
fork from diving. Also it has 'air assisted' front suspension (you
pump it up).

I was forgetting that with these new fangled hydraulic brakes on bikes
it's relatively easy to add a second actuator. Damned clever, these Japs.

(Cue Peter Sellers in Dr Strangelove, "The swine! Funny thing is they
make such bloody good cameras")


It also has a complex rear suspension linkage (Uni-trak) that provides
'anti squat' (the back sinking down on acceleration) so it was quite
technically advanced tool in it's day. ;-)

Although of course that doesn't prevent the weight transfer to the back
wheel



I guess as with most things it's a compromise. For me it would be
right if it keep the front wheel running smoothly on the road (no
patter or other anomalies) whilst providing the best ride for the
rider?

Agreed


Whilst the UK roads are bad, they aren't quite that bad so I think
some of it can be a bit suck it and see (within some constraints).

Agreed. If it really made such a difference you would use a multi-grade,
or change the grade from summer to winter. I guess since the quantities
are small they probably have a high viscosity index, perhaps even Group
V synthetics.
