Interesting demo for the xtrig. All the talk about coatings and friction being needed but we have this amount of stiction in the front end from clamps. Even worse when someone doesn't use a torque wrench. Wonder how the ride enginering, luxon, pc ECT ECT clamps would work?
Or WP/ktm really are that shitty compared to all other and we are all suckers for believing their marketing BS as well.
I am not saying that xtrigs are junk, (they have other good attributes) I am just saying that it is a clever selling tactic.

Did I remember that correctly?
Was that for the stock clamp or the x-trig/KTM power sports clamp? Or am I just high?

Also, the torque values are way lower than most people realize. My YZ calls for 17 Lb./ft at top and 14 Lb./ft on bottom.

Keefer, is there something I can do about the rigidity I am gaining with the WP XACT Pro Component fork”? Yes, going to a WP/KTM Factory Triple Clamp will help with some of the rigidity that the stock clamps come with. Also, you can go to a bottom triple clamp torque spec of 9N/m. Both will help with comfort on braking bumps, slap downs, as well as get you less rigidity feel through your handlebars.
I have Factory Clamps and Cone Valves on the way... so been reading all this stuff again lately.

Does anyone know who makes that torque wrench?
I am struggling to believe that.
Us mortals being able to feel the difference, I'd say no as well.
The wrenching accuracy for a standard clicker-style torque wrench is +/-20%. Set the wrench for the middle of the range to take the wrenching accuracy into consideration.
10.5 Nm +/-20% is 8.4 to 12.6 Nm - this helps understand why the OEM lists the torque range at 9 -12 Nm.
If you're one of those weirdos that greases bolts before installing, the nominal torque needs to be slightly reduced.
Pit Row
If your wrench is +/- 20% accurate and your friction varies +/- 10% (bolt coatings, worn bolts, dirty threads, some oil got on it, etc. can easily change this), then your actual clamping load can vary quite a bit.
Whether someone can notice that or not is questionable. Certainly if the bolts are too tight, it will cause bushing binding and that will be noticable. But if the bolts are not so tight that they cause that binding, I doubt anyone will be able to feel it. Unless they know that change was made, then they'll absolutely feel it!
I torqued my clamps too tight when I moved my tubes last year, and spent half a day bitching about how there was no way that bike could have won any kind of shootout before I realized my torque wrench was a mile off..
I also found out I need a better torque wrench that goes that low on the NM scale.
I just wonder how much better the X-trig clamps really are at limiting stiction in the fork tubes, are they worth the 500 bucks?
Even if they all torque to 9nM with the same tool, the experience will be different.
Now throw in they all have a different tool.. then who knows the effect will be, let alone all the other variables.
