Did you notice any benefit at all from the top triple clamp?

That's the weave we're referring to for sure in that video. I know its hard to tell in the but you can see the handle bars swaying back and forth in some clips. Couple of times the rear tire skids slightly. If that was rear steering from flex then the tire would rub the fender on the sides. I know on my bike, which is the 06 FLTR, I installed a 160 rear tire which only allows about 1/4" of clearance at some points from the fender and it never rubs anything. If I was getting .030"? flex at the swingarm axle then it would be quite a bit all the way to the rear of the tire. All of that swaying is caused by the triple tree design. If you want it to handle high speed cornering you need to change the geometry up front. The fork tubes and neck need to be in a straight line of one another then the rake and trail corrected from that point but harley reversed them to make the bike easy to handle at slow speeds.

I'm not saying the brace isn't a good idea but it's not the fix. There just isn't enough movement at the swing arm to cause that problem. This is referring to a bike in good mechanical condition.
I mention the FXR because it is basically the same frame. Only thing really different is the neck and triple tree and people still to this day say the FXR was the best handling bike harley built.

You seem to have a bee in your bonnet, so kindly share in engineering terms the basis of your thesis.
