Extended Swing Arm Shock and Spring Rate

endodoc said:

From what I remember, the Corse arm is engineered from the ground up so longitudinal and torsional rigidity is factored compensatory to the additional length. Not sure how this works with the sectioned stock arm. I have to assume multi axis rigidity would need to be factored in the suspension setup. That extended arm is for sure going to flex and twist with some noticeable difference

From what they are saying they buttress it with some extra internal trellis then weld it all up in a jig, presumably for that purpose.

The route you sent is clearly the best way to go, but I’m just not ready to research whether I have to redo the entire back end of my bike or not abs what all that involves.

I’m fine with other people doing the work, but I insist on understanding what’s happening and why with every part, that way I learn these bikes from front to back a section at a time.

So since you have everything covered on these bikes please explain to everyone what a baseline setup should be for the stock swingarm? What about swingarm pivot with eccentric pivot? How about ride height numbers or shock setup? We already know you won't have any that info.

When did I say I have everything covered? A baseline setup is dependent on rider and rider style. I'd also say talk to @roadracerx if you want cogent suspension set up info. But that expertise isn't for free (at least for the V4 platform).

Yeah and I’ve had enough aerospace Job Shops as clients over the years that owe me some favors that I’m pretty sure I can get anything made out of any material, abs the scanning technology is so accurate now that they can just 3D scan a part, modify it in any way, have everything line up within very very close machining tolerances, and do it in any material imaginable.

3D scanning is an absolute game changer in that industry.

You should have all the answers dickwad since you troll this place 24-7. Not once have you been able to back anything up. Me asking Roadracerx for setup help would be same thing as him asking Dave Moss for help. Stick to the Lounge section man you be better off.

So is 3D printing.

The headers on my Porsche are 3D printed Inconel…that’s one if the most difficult metals there is to work with…and now they can print with it.

For sure.

In the most simple of terms, are there any structural differences between cast/forged and 3d printed? As in, is would a forged and CNC part be much stronger than a 3D printed part?

3D Inconel...I bet that was affordable. In a few years I'm sure that manufacturing will trickle down. Time spent being the greatest expense.

3D printed is better than forged because you can do more engineering, you can make shapes and architectures that you simply can’t do with forged or machined parts, gives you the ability to engineer shapes that are lighter and stronger, internal honey combed cavities etc.

The biggest cost on getting Inconel parts printed is buying the machine time, it takes hours to print that stuff, each bead of metal is melted into place using lasers. So buying time on the machine is by far more expensive than the Inconel material or the engineering time to design it.

Well then my friend, maybe you can help me out with a part or two LOL.

To a complete layman, I thought the benefit of forged was the metal grain was, or could be controlled, to the benefit of the part. Maybe that's just hammer forging, I'm not sure.

There was a time that a VCR would have been hugely expensive. Now, you can't even find one. It will get cheaper but it may take a few years to get there.

That’s basically the same process we went through for the 911, and we used the same printer shop, in the background you can see the end caps for my intercoolers that they also printed on a table.

Basically with 3D scanning and 3D printing you can make anything.

Talk about the pot calling the kettle black. Literally every post of mine is followed by a post from you. Like you seek me out. Let’s call it stalking? Maybe trolling? It’s like a blind person looking into a mirror

Why the .... do I have to back anything up for you??? I don’t have to prove anything to YOU. Who the .... are you? You think you’re the king ....… more like a piece of ..... Take my advice or leave it.

But what I do know is that you have a mental problem. It’s called borderline personality disorder. There’s probably a little narcissism and lot of ignorance also mixed in. You should really see someone about it.

Sorry for Mick being a ...... and once again ruining a thread. Back on topic…

Here’s the SBU video on the Corse swinger:


Side note the Corse WSBK and Factory swingarm are way different

We all won't have to worry about it ....... liberal troll the tools are coming and you will be long gone so start joining up here DUCATI modified Forum cause soon you won't be here.

Here we go again more garbage from you the question will continue why are you even here? No bike, no knowledge and nothing to contribute here but bunch of nonsense give it up man.

You are correct, however you can’t forge complex shapes.

You would want to forge a wrench, hammer, pressurized cylinder, etc.

You couldn’t forge or extrude something like a swing arm out of a single piece of material unless it was solid.

Silliness should be refrained on the street or you’ll end up like Vicati.chasing tenths on the street will always lead to problems. A novice rider shouldn’t need an extended swingarm. These bikes are quite capable out of the box no matter how much whinging goes on here. Improve your skills first and then the bike will follow. Sounds like you need to get to the track and work w a coach. It’d be money better spent

ridiculous… shut your mouth, let me put you in your place real quick, you don’t know what actually happen and you don’t know who I am, I’m not a novice rider, not pro either but i know what I’m doing/ talking buddy definitely not chasing tenths on the streets but maybe your judging me based on your current decisions on the street, I don’t race on the street to prove how big my .... is, it’s just is, I just ride…if I go to track to ”chase tenths“ and another thing @Steven31371 asked 3 questions but I since your trying to be the male version of a Karen and nagg about another rider how he got in an accident, you missed it, you missed the questions

QUESTIONS he asked.
For those if you running an extended swingarm, what rear suspension setup are you using, and how much did you have to increase your spring rate in the rear?

Does anyone know an aftermarket spring supplier (not Ohlins) with the same spring length as the Ohlins spring for the Ohlins TTX36 but that has a higher spring rate than 115?

Is there a shock setup other than the factory installed Ohlins TTX36 that will allow the continued usage of the Dynamic Electronic Suspension? (Which I like our on the street)


there here if you missed them on the OP, see the thing is this is a forum not let Me ask if mommy and daddy fine with the mods do on my bike … the forums is to learn from each other share data or learn from the few actual racers there is here or dealership owners or anyone with extensive knowledge here, ......... like you ruin and fill our forums with fluff,, {unnecessary ........} like @Mick1976 said if you have no value to give to the forums or OP then don’t chime the .... in. Who asked for you advise Anyways? NO ONE because your nobody. Like who .... here knows you... .... you Know what keep talking .... about me because your making me famous, and you know what it doesn’t impact me negatively… I’m honest about what I do. carry on loser boy.

but check out lounge section you little not knowing wtf about bikes .... heads can freely talk .... over there.
