Ohlins TTX series

Astral11 · Sep 30, 2023

Will the suspension guy please enlighten the forum on the internals/manufacturing/Ohlin part numbers of the shock absorber used in the 2020 V4R, 2020 Superleggera, and the latest DU 468. What are the differences aside from manual pre-load adjustment on the 468? Ohlins website shows the 468 as the only available upgrade, yet there's massive price differences that I assume relate to performance? Also, what are we to expect for the updated 2024 V4R in terms of suspension?

V4R - 36521652A priced at $2,734
Superleggera - 36521881A is $4,020
DU 468 is $1500

Superlegera has a titanium spring. Potentially other titanium components?

V4R comes with hydraulic preload adjuster now?

468 no hydraulic?

I will have DU468 w/ pneumatic PL adjuster for sale soon - brand new
if anyone is interested

Astral11 · Sep 30, 2023

The 20' doesn't have a pre-load adjuster, just compression/rebound and spring. Or is the spring preload adjuster that's on the 468, the 24' update going onto the existing R shock? Why would downgrade to the 468 from the S or R shock? Did CNC upgrade the internals on the 468 to a GP/SBK spec? But they keep the same price as stock Ohlins?

The SL titanium spring is understandable but can also be purchased separately and installed onto stock OEM, maybe just refined internals. If anyone has the price for a titanium spring that could help explain the price differences.

It's almost as if the shocks are proprietary to Ducati or deemed model specific to the market. You can't find the TTX installed as an option on Ohlins, only the 468. There's a lengthy thread on DucatiModified that I'm waiting to chime in to, but it seems there's more purses being thrown at bikes rather than making informed decisions

All I have to say about the twin tube shocks is where were they for the rest of my life. Both more supple and controlled.

Astral11 · Sep 30, 2023

Borrowed this pic from a separate thread, going from an S conversion to 468.

Are the labeled numbers not the same function? The ECU managing the S rebound/compression and spanner nuts for spring preload, compared to the hydraulic hand valve on 468 that set preload and the manual R/C adjusters? That S TTX 36521961A goes for $2680 by the way. Are these shocks not the same products in theory, just manufactured differently? Ohlins seems to think that 468 is a better upgrade, how?

I get the build/maintenance aspect of owning a bike, but upgrading the internals or buying electronic bypass kits, and the downtime during rebuild or troubleshooting...doesn't it add up $ and should they not of just bought an R that you can take straight to the track from the dealer?

BP PanigaleV4S · Sep 30, 2023

Top is compression and bottom is rebound. The S shock is nothing more than a TTX with electronic adjusters and manual preload rings.

36521961A is only as expensive as it is because its a Ducati dealer part. If I were to ever need a replacement, I'd buy a used for under $1k and send it to Ohlins for a refresh. The SL shock is only that expensive because of the Titanium spring and how few of them there are. The prices do not reflect any change in performance outside of maybe slightly less weight with the Ti spring. The SL also comes with Supercorsas with red lettering and a red stripe. $1,200 for a rear. It's not better performing, its just there's there so few of them.

Right on, thank you for the info. I'll pass on the DU468 considering and try to find the Ohlins sheets for OEM rear shocks

On the front side of the bike - FL 9540 0048 - the Ohlins manual is listed as FK124 for the V4R.The performance between the FK129 S forks and FK124 forks are just about on par. The 124 has 5mm less fluid volume and larger pressurized air gap, but the stroke to reach 148N is almost the same with 129s. 230mm stroke with 120mm fluid level on the charts. The 129s have less mechanical compression on the fluid, the lower preload settings are in line with the in-compressible fork fluid/spring transients, relying more on the spring cartridge for suspension performance. The 124s use a more compressible air bubble, and require more preload against the bubble to firm up against the cartridge, higher preload settings. What is interesting though, the springs are interchangeable for riders, so in essence the 124 is only a 5mm larger air suspension, with a more firm stroke or a quick chop to a higher force ramp and less compression length allowed overall, compared to 129s longer stroke, easier or softer feel while ramping on force, but having more system rigidity or a rougher dynamic due to a smaller air gap and relying more on spring transients.

What year is your bike? The newer Panigales, even the V4S have gas charged forks. My 2021 V4S does not, but I think 2022 and newer should. This would include the V4R, but I’m not sure about older V4R examples.

V4R is spring pressurized

The question started with reviewing the manufacturing/perfomance details of the R, SL, and DU468 rear shock absorber and the open ended non-sense of why folks are using the DU468 and not staying with the OEM suspension they paid for. While searching for that I came across front fork details between 2 highly debatable machines. The topic of suspension performance is of point right along with engine performance, and there's quite a bit of S front suspension being re-built or hacked down to a manual configuration. The S forks are not much different than the R.

I have a 2020 V4R - the fork manuals/charts are directly from Ohlins when searching the V4R and V4S, the FK129(S) chart was published in January of this year - unless there's a different chart to refer to?

I meant the 23 R.

Oh, you don’t even 23? Lol

BP PanigaleV4S · Sep 30, 2023

The V4R OEM is the Ohlins NPX25/30 gas pressurized fork.

FKR 129 is a gas pressurized cartridge kit to install in an OEM fork. I think this would be an upgrade for V4S owners, especially on bikes older than 2022 without gas pressurized forks, who were actually fast track riders but otherwise stuck on a V4S.

The gas cylinder in the OEM fork is visible when looking at the fork bottom. It appears as a cylinder molded into the fork bottom perpendicular to the axel centerline.

I think to install the gas pressurized cartridge kit, you block off the passage in the OEM gas pressurized fork. But, I don't think one would put a gas pressurized cartridge in OEM gas pressurized fork.

I doubt it. The cnc body wsbk shock (rsp) from Ohlins is like $7500.
