Bearings would be nice. Ducabike sell these linkages. Not sure if the dimensions are right. Adjustable though.
 
Ha ok yes, I didn’t factor the application. Everyone kept posting pics of links for the 99 suspension. VBs nice representation looks exactly like the Motocorse link for the 99 without the bearing. So it’s the side links. Yes In that case the double rod end is not the best solution. Would have been helpful if Andy posted pics of the application in the beginning. I swear there is a pic out there of an alternative to this linkage that doesn’t use the side plates.

I imagine you'd need to redesign the actual linkage, I guess you'd do the WSBK linkage.
 
There ya go, a proper suspension linkage. If you’re already going to enlist the services of a programmer and a machinist then you are no longer limited by some rendition of the original design besides this place could use someone doing something interesting, it’s been a ghost town for anything new.

If you’re going to stick to the side link design I thing VB produced an excellent solution. Either way synchronizing the links would be the only hassle. Other than that it accomplishes what Andy wanted.

I cant believe Ducati corse are using pinch bolts on their tie rod... honestly what thread must they be using on it..

The RS proper linkage requires the rocker, the tie rod, the shock, and the swing arm.... if found that would be some proper money. If you wanted to utilise this set up with a std swing arm then that would need machining..... now it does look possible to machine the std swing arm to accept a RS rocker and tie rod, machine the std arm and use the RSP shock bottom mount on the std TTX shock...

This solution provides a well fitted non intrusive adjustable pair of items capable of being accurately adjusted on the bike whilst its on it stands, though I think I will need to lower the belly pan 6 screws to access it.
Using screws to lock the threads is better to undo with an Allen key than trying to get a pair of spanners on to two lock nuts because its 90 degrees to access them

Using it alongside a ride height tool provides a consistent and accurate height setting when you alter the chain or choose to alter the ride height...

By using the two female ends as per the cad drawing you can easily synchronise their length by a simple measurement between their ends.
 
Just measure between the pinch bolt bosses. Lucky they're there!
 
All this to fine tune ride height? Also what’s the application: trackdays, racing? Trackday racing? Seems like a lot of time, effort, and money being chucked at a problem that’s probably low on the totem pole when it comes to maximizing this bike

Thanks .. you stick to not working out how to set your sag correct, I can see accuracy isn't very important to you..

Serious question though. There’s a reason why this hasn’t been done before. But I’ve done some napkin math on this… From what it looks like, you have the stock linkage. By adjusting the length of these tie rods instead of the shock itself, it will put you in a different spot of the progressive link kinematic. Shortening these tie rods will start you farther up the rising rate of the linkage and vice versa. Going to a Forsaken linear linkage would probably help remedy this to some degree. But I’m sure @andyb has modeled this on Motospec…
🤔
@Bruce Wayne might have better insight on this matter.

Also any length discrepancy would cause the system to bind. And you’d most likely have to unbolt at least one link as you’d be constrained by the contralateral one. Seems a bit of a faff.

I’ll stick to working on my sag number…

Whilst you are at it go look at pretty much any Ducati …916 onwards look at the rear suspension geometry make up in particular ..and how Ducati alter and or correct ride height…🙄
