It's pretty complicated. When you change the swingarm position, it effects wheelbase and ride height. So it's not like you can just move it from -3 to +1 and go "Oh, it had this effect".
But, the Superlegera doesn't have the adjustable pivot, I think it runs the same as the base bike, which is +1 on the V4R. But, the SL also runs a longer swingarm.
Setup, is not the easiest...

Some good info here (1199 and 1299 specific)

general article on geomerry...which adjusting the pivot affects...everything is a compromise and this sums up how it all interrelates.

Very briefly, if I understand the Ducati blurb on the 1199R, the very basics are:
+3 Best drive in the dry, least stable
+1 gives good drive in the dry, not as stable
-1 gives less grip, more stability
-3 least grip, most stable
But, these changes will all effect how hard it is to turn the bike too.
And, I'm not 100% sure if my understanding of what the Ducati advertising giberish meant is correct.

But I read this on another forum, which is kind of exactly opposite to what I said:
"Yes it would, but that's not what it's adjustable for. There are other better ways to adjust ride height.
Adjusting the swingarm pivot changes the way the bike comes out of corners.
For example, if the ride heights are good and spring rates are where you want to be, compression and rebound are working good, yet the bike has a tendency to run wide on corner exits, raising the pivot would help keep it on line. It would keep the rear from compressing so much, therfore increasing rake and trail.
Conversly, if rear traction is lacking, lowering the pivot would give more weight transfer, causing the rear tire to hook up better." ChuckRacer ducati.ms

Yep, I think I have it the wrong way around.
+3 - Least grip, easiest to turn
-3 - Most grip, hardest to turn
By grip, I'm referring to corner exit grip/traction.
So, I would imagine, if you went to -3 (relative to +3), you would want to increase rear ride height, or decrease front ride height? Although, I initially found, with the stock SAP at -3, I increased rear ride height, and increased front too.
When I tried SAP +1, I reduced both.
But, it's all a work in progress.

Guys, what's the optimal Swingarm length ? I hear 604mm but want to double check.
What kind of gearing do you run ?

I think I've gone to 15/44
Swingarm length I'm using is the maximum possible, can't remember the figure off the top of my head.

Does anyone know if it possible to retrofit the V4R eccentric adjuster plates to a standard V4?
With the recent launch of the 2022 bikes, it seems to be all about the raised SAP.
It would be an interesting little project if not too expensive.

You can, but the V4R swingarm is different, to allow adjustment.
A better move would be the parts from the 2022 V4. Probably only about £300 in parts, and you then have two positions available. Stock (+1 on V4R) and 22 position (-3 on V4R)

You'll potentially want the new shock linkage, more linear, less pumpy.

Thanks Rick, makes sense. The blurb from Ducati was that the 2020 bike had the same rear suspension linkages etc as the V4r... but checking the tie rods, they are different. As you say the swinging arm is different. However the rocker arm is the same.... The V4r had a 105 N/MM spring, the V4 2020 has 85 N/MM.
In your second message, you mentioned about a different linkage - do you mean the tie rods? They are pretty cheap relatively. I was looking at the Forsaken Motorpsorts linear rocker (designed for the 2019 bike, but it seems all the Ducati originals are the same 2019 - 21).
It's a minefield.. think I should stay with what I've got

Swingarm pivot position on the pre-22 bike is different from the R, and this effects what weight spring you would use. Also, the designed usage of the stock bikes vs the R, you'd potentially want a softer spring on the road to be more comfortable and to work better at lower speeds.

Apparently those plates are not interchangeable between the 22 bike and the earlier bikes. The swingarm may be the same, but there's something else different too, maybe on the crankcase?

I thought they raised the pivot point of the swingarm which would mean the case is different.
