These forces use the tire, wheel, and axle as a kind of a lever

This dynamic misalignment CAUSES STICTION
that no amount of static "forks-alignment procedure" can eliminate !!!
Right, well there's an action on the forks I didn't consider, one fork compressing more. That puts a new light on what a fork brace.........braces.
A curved brace like my oe pie plate would not offer a lot of opposition to said action.
In this context I can see where a telefix would offer support.
What ? You say BMW forks are immune to dynamic flex ?
Start with perfectly aligned forks, and try this simple experiment,
an easy one for the 98% :
Block the front wheel in a lift vice, sit on the bike, turn the handlebars –
and watch the front fender move laterally across the front tire.
This is the walking flex I thought to be more of an issue....
Another test is to wobble the handlebars side to side on a fully loaded for touring, two upped bike when sitting still. Nauseating to say the least.
And for the "2%"ers :
While hard into a curve, look down and notice
that the front tire is no longer centered under the fender.
Hard braking will actually stuff the tire backwards towards the frame.
In a controlled situation and with a little presence of mind, you can actually
watch it happen.
So, you don't need a fork brace ?
For me, motorcycling is not the nostalgic memory of an activity relegated to bygone years,
nor is riding always so sedate ...
But, apparently even the BMW factory would disagree with the premise.
Larger diameter stanchions and a fork brace were stock issue on the Type-247 in 1984.
I don't know if I need a fork brace, I've never tried one. I've never needed to try one.
Mind you when an old farmer finally buys a new tractor.....
It is simplistic to say that only "2%" of riders will "notice the difference",
and although speed will certainly accentuate inherent weaknesses,
the statement does
not present the entire picture ...
A (better) design will function strictly according to the laws of physics –
regardless of the rider's appreciation or ability to notice !
What might be an essential improvement for those riding at speed
might also serve to make riding and handling
EASIER and more enjoyable –
at any rate of travel.
I'm talking about
less rider input, less effort needed, a less tiring day on the road,
to affect any and all of the required responses that we expect and need from a motorcycle.
In spite of our chosen preference and fondness for the old airheads,
one only needs to ride a contemporary motorcycle
that has addressed these antiquated chassis technology issues
to appreciate the difference !
Never! 
/5 through post /7 BMW telescopic forks,
(like many forks systems on the market in those times)
are best described as al dente spaghetti -
If you are happy with all that –
enjoy it with marinara !
