2023 V4R, anyone else disappointed?

The front of the swingarm itself is raised by lowering the pivot, so the effect is a lower pivot. Don’t confuse the physical swingarm with the pivot point. Here is a better graphic. F6404725-FDED-487C-AAA8-4358A4ACCD6F.jpeg

If the pivot was fixed within the swingarm rather than the chassis, they would change position together, but the method Ducati has used is a fixed pivot and moving swingarm.

Most other bikes (Aprilia for sure) use eccentric inserts that move the actual swingarm and pivot up/down. Ducati must always be different like employing a SSSA rather than conventional double sided.

Glad thats all cleared up then......

Heres the different parts between fixed and R pivot.

Looking at Item 1 and 2 shows the eccentric. you should be able to see the outer parts of 1 and 2 stay still and the inner parts can get higher or lower depending on where they sit in the rotation.

This is a still from SBU build you can clearly see where the SA sits in relation to the bolt head.
As it is there I would say the SA is sitting in its lowest position and least SA angle. If the bolt head was rotated 180 degrees anti clock wise the eccentric would place the pivot of the SA higher and hence more SA angle, more track orientated.

LOL Ok, in this SBU photo it looks “correct” in that the SA pivot follows with the SA such that it “works” like we(?) think it should. That doesn’t look at all like the photo andyb posted of the 2023 “production” R at the press intro.

The parts diagram of the adjustable pivot also looks correct, so it must just be my interpretation of the press photo is wholly incorrect! The + numbers are “up” and - are “down” for the pivot. Carry on!

there is no foot peg on it atm?

which photo? plus this is a 2020 v4R.. I suspect the parts/process is the same.
 
here's another curve ball for you... there are four positions to adjust between, that means three spaces between them each of 2mm.....in total a maximum 6mm raise or lower of the SA top to bottom...

Why is this a curve ball? That just the range if adjustment. Am I missing something?

Isn’t the range -3 to +3?

6mm
 
To makes thing more obfuscated, as you turn the eccentric pivot you’ll also be changing wheelbase. Dun dun duuuuuuun!

Realistically unless you’re racing or are a very high level trackday rider, you wouldn’t know the difference between +1 from +2. Maybe you might notice +3 to -3. Most of us are literally hanging on for dear life and have a death grip on the bike and can’t feel anything but a shear terror

The V4 SP2 has "Stylema R" calipers. Visually, it looks like the R calipers have two red line/stripes near the bottom of the caliper to distinguish themselves from the regualr Stylema. I couldn't find a spec on the 2023 V4 R calipers, but based on pics, I do not see the red stripes.

I get why the carbon fiber wheels are on the SP2 and not on the R, but it looks like they cut costs of the brakes too lol.

Actually WRS gave me a steal on the damn thing. I had purchased the 650 for another project and didn't even know they had the 4040 which they don't any longer, I'm told its no longer available "shocker"and I ordered the thing back in June. I called Michell at Brembo North America and she said they have never seen one come through their warehouse and that most of them go to Taiwan. Those guys have some insane builds. All lunacy aside, its a nice piece. I'm going all out on learning CNC work and buying a bunch of equipment in 2023. Being able to make things on the small manual mill and lathe that I have has been a game changer for projects. In so many instances it has given me options where there otherwise wouldn't have been any. Having a fab shop at the house and learning how to use it will allow me to add an even further degree of uniqueness and customization to my many projects. You show a nice billet ridiculously priced Corse part to a Ducati enthusiast and they marvel at its unobtainium nature. You show it to a machinist, "yea, come back in an hour". Increasing your capabilities builds freedom.

because the V4R you buy for your 50 something K, is miles away from the one on that video.....for a start!

I just re-read my post. Where does it say the video posted matches the bike for sale?
Oh sorry I forgot.......You are the resident............

Well, it's like this Andy:
Ducati - swingarm raised 4mm.
Reality - swingarm goes from +1 position, to -3 position.

The reality, suggests a change of -4. Ducati advise a change of +4mm.

Ergo, I am unsure, of what moves in which direction. I'm pretty sure, there is a change of 4mm, one way or another.

Potentially, the frame markings indicate the chassis position relative to the swingarm, and Ducati are describing the swingarm position relative to the chassis.

My understanding is that the later bike swingarm pivot point was raised 4mm to the +1 position of the original v4r, and that the adjustment range references the pivot point within the chassis:

+1 higher (greater swingarm angle relative to horizontal, greater anti-squat)

-3 lower (lesser swingarm angle relative to horizontal, less anti-squat)

+1 is the same as the pre 22 bike.
When I tried +1, I ran shock length of 318mm (but obviously fairly useless information without wheelbase or comparable ride height measurement).
I ran the forks flush, but had Mupo cartridges, which give a different fork length anyway.
I did about 3k miles with +1 swingarm position, never found a brilliant setting. When I went back to the -3, bike was so much nicer to ride, for my riding style. The bike, with +1, was incredible on the brakes and throttle, wouldn't corner well, and mid corner speed was low. Reminded me of the description of Dovi's GP bike.

So your understanding is that the -3 position raises the swingarm pivot 4mm higher than the +1 position?

That seems counterintuitive.
