Ohlins TTX series

Did you understand the details about the spring rate? Someone has to disseminate info if DU468s are the best and clearly not, they seem to be just for adjustment at starbucks and not the track, so defending my Right to R as much as possible lol
 
OEM ohlins is really good
FKR + DU468 is better
case closed

It seems the RSP40 was previously mentioned and read right over...not sure how the DU468 is even quoted as acceptable

And if this was somehow forgotten..we already have details on the spring rate related to the stock/Forsaken linear linkage...all the way back in 2021
I made one for my V4R last year working really good, std links are way too progressive.
You will definitely notice a difference under hard acceleration but you need to make sure you get spring rate correct and might have to play around with the shim stack depending on your race pace.

DU468 is the best shock you can buy for he V4R, RSP40 is for a sbk - there is absolutely no reason to run one on a V4R that isn't a V4RS.

Did you even look at the comparison between the 466 and 468? It is clearly in the numbers so I'm not sure what you're referring or quoting to that it's best for the V4R or S. I disagree, provide a spec sheet if you have one, otherwise the 466 clearly outperforms the 468 on any V4 just by ride hide adjustment alone. You must not see the OEM design clearly and how much more robust the shock absorber is, or you're just a fan of the handle bar for starbuck adjustments or to say you've "upgraded" the rear suspension, when in truth you've cut the bike short. I would not remove any Ducati OEM shock absorber unless you're upgrading to the RSP40 or building up a V4 base, then sure the DU series will be fine for the casual street ride which is what the bike is designed for, not track performance like what you start to pay for once you get into the V4S or V4R range. Are you referring to the V4R - SP? That just comes with carbon wheels and the 1103cc engine compared to the homologated 998 V4 with top Ohlins suspension? Provide a link of the RS you're referring to. You have also not alluded to the replacement shock absorber - Why are you selling a brand new DU468 if it's top of the line? Why would you degrade from OEM to DU 468 - and now downgrade to.....?

You sure about that? The normal TTX top cap us forged which is better than billet

You must not be considering surface finish or machine radians that affect heat tolerances or stress alleviation which matters at MotoGP/SBK - that is also why there's a pneumatic locking collar on the RSP compared to the 2nd spanner nut on my TTX, because of heat cycles that cause the upper nut to lose torque. Or are we questioning the RSP link provided, that shows a cap entirely machined?

You're correct the OEM is forged and I didn't doubt the process and say forged was better than billet? Also why I run proti bolts, not run of the mill titanium.
If Ohlins forging process is correct at the exterior, which it is because I don't have further machine marks on my forged TTX, there's no need for machining anything, besides the internal pathways which can obviously be done billet or forged. But you can always forge it and further machine it to slim down on weight or relieve the stress areas of any excess material. The valve body is not an easily forged form compared to a bolt head, but Ohlins figured it out, and I would even bet the OEM V4R shock can be machined down in some areas. Kind of like the machined FS linkage compared to the forged linkage. I would love to see a comparison of the V4SL - R - RSP40 valve body as Ducati specifically made the SL to be lightweight, but how in comparison to the R or RSP40, the SL valve just adds to the mystery.


I wonder if any of those DucatiModified folks can chime in...supposedly there's full blown S to SL conversions there but the authors don't provide much info on their builds or able to check a fuse correctly, much less refer to a spec sheet
 
Tell me what the biggest difference is that you see btw the DU466 and DU468 - cause there is a really big one...
 
It's an updated design specifically to include the hand valve adjustment which came from street/occasional track rider feedback of the DU466, wanting a quicker adjustment. It's the same design in essence just with the hand valve

You do realized you're not addressing your opinion of using the 468 or providing any technical data behind it? Along with the technical details, the V4SP you mention, and the replacement of the 468 that you're selling, do you know of any pictures or any rider in SBK or MotoGP running the DU468? Aside from "GP" being mentioned in the Ohlins catalouge, that does not make it suitable as "GP" or OEM replacement, it's gullible marketing that people fall for.

Comin’ in hot 🤠
 
Pecco uses 2 DU468 shocks instead of forks on his GP bike, google it

Lol damn you got me there...🤣 do you even know what we're talking about? You seem to not have a single valid point to this conversation. Pecco du468 and all you get is a subpar rear shock that has no use on track or Pecco with carbon ohlins forks up front and a hidden rear shock

So you running those 468s up front or what? what happend with the FGRs? @andyb this man needs your suspension assistance
 
But truth be told, the rear MotoGP shock is hidden in the frame - secret sauce for sure but we know it's electronic because of rear squat during launch

I’m under the impression MotoGP regulations specifically prohibit any electronic suspension control including ride height devices (which have to be mechanical).

Edit:

“While some teams had previously dabbled in holeshot devices, MotoGP's ban on the use of electronically controlled suspension kept full ride-height devices at bay until Ducati surprised its rivals by creating a system using only mechanical and hydraulic parts.”

@astrall11 you could be a little more humble in your inquiries and you might actually get a good answer.

Did we miss the "case closed" comment from @KarlKani, that has provided nothing to this thread?

I envy the streetfighter in you but we have had relevant information regarding the TTX series and dismissed the DU468. IMO if it's too hot get out the kitchen 🤠

Craig has been helpful with the RSP40, and all the spec sheets I've provided came directly from Ohlin's website. Those specs are being denied, and the truth hurts to some. Humbleness doesn't apply when biased opinions towards facts are disputed, especially in the face of blatant ignorance, let the truth be told and only that.

And if that's the environment:
RSP40 for the rear shock
FGRs up front
CASE CLOSED

This guys a riot! It’s like stream of thought. Thoughts that are not well formulated
