I would be interested to hear if you guys raised the bike front and rear at the same time. I had a S1000RR track bike that I raised front and rear 5mm and it was the single biggest difference I have ever made to any bike . It took half the day to get used to and stop hitting ripple strips on the inside of corners. Doing this acts like a pendulum and really speeds up the way the bike turned.

I have been running my V4R with the forks flush with the (stock) top triple clamp. I ran the shock up to 317mm at one point (don't have the wheelbase measurements to hand, approx 598mm).
The bike always lacked something, generally stability on the throttle.
I've now got 2mm fork showing, approx 6mm fork preload, and shock at 312mm with 11mm preload. Same wheelbase. The bike is now epic on the brakes and throttle, and turns extremely well and generally feels planted. It does feel less 'flickable', but depends on your riding style, and circuit you're at. Next time I'm on the bike I'll be trying reducing shock length further.

What's the length of the rear shock from the factory? I don't have it in my notes.

Which bike?
The 22 V4 base, I measured at 315mm, but manual said it was 312mm?
My V4R came with 312mm, but recommended 315mm when you go to the Akrapovic exhaust (from Ducati manual)

I had presumed they were all the same. The 2021 Panigale V4S owners manual doesn't list the shock length, just the travel which is 130mm. The only workshop manual I have is the 2018 Panigale V4S one that's going around.
Interesting that the V4R manual gives a different length with the Akrapovic exhaust.

Hey RickD996, are you sure it's 315mm for the Sachs?, mine is a 2019 base which measured was 310mm and when I remember correctly in 2020 MY they've gone to 312mm and is still so for 2022MY.
I also ride the forks (showa) flush and tried different lenght for the shock (now TTX)and 312mm gave me the best feeling. What springs (front/rear) are you using?

**Also not sure in the manual but shock length is measured at top out

I don't use a shock extender, so can't measure it at top out. I have two bolts, one has a cone tip, the other is flat, but I have cut a groove in the centre, so I can measure from centre of each eye. And the Sachs 2022 shock, is definitely 315mm. Which, I'm not surprised about, as my friends 2019 V4R had a different amount of preload from factory as my 2019 V4R! But, the Sachs units are fixed lengths, so surprised about the indiscrepancy. It being 315 didn't surprise me though, as it's more inline with the chassis geometry with the different swingarm pivot, and how Ducatis come from the factory.
Cheer man, maybe I'll remeasure the shock in the next vlog!
Thanks, Rick, I also don't have a shock extender for the top out and I use the same method with the bolts .
I had the Sachs also measured with the suspension guy who has the special tool for it and he measured 311mm, so I was a 1 mm off and 'modified' my tool a bit.
So they must have changed the shocklenght because 4 à 5 mm is a big differents! I can't belief that these are production tollerances.
I'm interested because for next season i'll change to the 2022MY, so all info on chassis is welcome.

I can tell you my 2018 V4S was much shorter than 313mm from factory. Rick asked me to go to 313mm and I had to keep unwinding the adjustor quite a ways till it maxed out at 313.5mm.

In my notes I have that there were 6mm of exposed thread at the bottom of the shock and 4mm of exposed fork above the triple. If I ever have occasion to take the shock off I'll have to measure it.

If you are still bottoming, add 5ml of fork fluid to each leg, see how you go next session. If it helps, but still bottoming, add another five to each leg.

315mm on the stock Sachs length seems fairly accurate. Definitely no less than that. I also used the 2 bolts for measurement as I don't have a shock measuring tool. As you can see from the photo below, the Sachs is still around 4mm longer than the Ohlins TTX after I lengthened it by 2mm (312mm). Of course its not an ideal way to measure but thats the best for now.
Installed the TTX at a 312mm length and dropped the front by 4mm and then 8mm (FKR cartridges)... Still doesn't feel right on turn entry and mid corner (slow turn in, hard to flick tightly). Would have tried shortening the wheelbase from the chain adjuster but it seems to pump on corner exit so not a good idea... Any knowledgeable opinions welcome.

Which forks d'you have WetDog? And which track? At Brands GP and Spa, I have the base bike forks flush with the top yoke. But at Oulton Park, I had 2mm showing and 4mm less preload on the forks.
I'm running the shock at 307mm now.

But, shock length is kind of irrelevant, as the hub is concentric :'(
If you pit the bike on footpeg stands, then measure from the hub to the rearmost (of the two) tail fairing bolts, I get 565mm or 570mm, can't remember!

I raced a BMW S1000R and the single biggest change I made to the way it steers was to lift the front and rear by 5mm. Doing this gave it a pendulum effect where it would drop into corners. it actually took half a day to stop hitting ripple strips on the inside of corners. Doing this seemed to have a massive upside without having to pay elsewhere. Here is a video with this set up and you can see how it turned and behaved itself
