yawn… unlike you I dont post if I don’t have value or data to give, I’ve never have ran an extended swingarm on my Panigales and I’ve had 3, I think it’s a great option out there, all I know about them is whaT @cycler told me about them. also no I came to the post to learn about them because @Steven31371 asked some great questions that Im interested in knowing as well, I’m a bike nerd I enjoy this ...., but im also going to put you in your ....... place, trying to use me as a bad example. Like who are you again?

listen buddy sit down and re read my post, now you in ya place. Have a gn.

I’m gunna put the Pierobon extended swingarm on my bike. It extends the Swingarm by about 35 mm. This will necessitate using a heavier spring rate on the rear shock.

The problem there is that I’m already using the heaviest spring that Ohlins makes for the stock shock that came on my bike, which is the Ohlins TTX36. Has the electronics package with the Evo 2 that I’d like to keep.

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)

I will put the data into our motospec program and see what effect the longer swingarm will have on the rear wheel force, my gut feeling is it won't have a noticeable effect but happy to post results so at least you have some data to help you.

Stick one on Steven but in my opinion at this stage of your riding career, its just bling. Love to hear how it goes though

No disrespect but you are in your head at the moment looking for solutions to non existent problems. Want to build a ....-tastic mega fuckerama road bike? then absolutely do it, but you will not appreciate the benefit of any of these expensive mods without doing the yards on track or on the road. The general principle is when you are riding past what you have e.g. your brakes, then chuck on the sicoms, when you are needing that extra drive from the swing arm then fit it.

Get that bike of your clocking miles with buddies who ride fast, get to the track and when you start going fast then you are ready for the heavy duty upgrades

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.

What is your obsession. Leave your argument with other members between you and those members. No need to mention Ducati modified. Quit trying to paint the forum in a negative light.

Who ....... asked you to chime in your another one that sits back and trolls this place 24-7. Your a moderator and post daily on Duc Modified but never post anything here that pretty much sums it all up ....... clown.

You did when you mentioned us. If we did a poll here I think the majority would think you're the clown. If there was a vote to kick you'd be long gone. Since this place is the wild west you are allowed to act this way. What's interesting is you would never talk to anyone like this in person. So it sums up who the real clown is.

Mick1976 · Nov 6, 2021

Bring it man name the place and time. You and the other clown have been trolling this place way too long so the tools are here now and the changes will be made shortly bye bye!!!

I’m thinking it’ll have a 2.4% difference in wheelie-ing less (extension/wheelbase*100). So probably not noticeable.

Dude I’m not gunna pile on here, and I do think you are well meaning, but most Karen’s are lol….in a friendly way, that’s me saying you do come off a bit Karen-ish. I’m a 50 year old man, that while new to bikes, have been pushing Motorsport limits for close to 3 decades now, so I don’t need life advice on the subject, technical advice is GREATLY appreciated though, as nearly all of you know more than I do about these bikes.

Generally speaking, if every time I ask a question about the bike you say no no, you shouldn’t do that, and the reason given has something to do with you mothering me instead of a technical reason, it’s probably gunna be advice that falls on deaf ears over here, and rankle some feathers at most forums like these.

After all, we are talking about Ducati’s, not Vespa’s, if not pursuing excitement to the limits of our PERSONAL willingness to do so was not in our DNA none of us would own these bikes and actually RIDE them.

That’s awesome man, thank you so much, if it’s useful data to add in I weigh between 250-260 with full gear on.

Maverick said something useful to me while I was picking up another bike at his place and talking about springs rates on the gixxer track bike…the bike I bought from his buddy is set up for a 230 pound rider, I’m 250….but that bike is a race bike set up for a 230 pound guy that raced in Championships with it, so he’s a bit lighter, but he probably put way more load on the bike than I ever will at open track days. So the 30 pound gap between us probably won’t load the spring any more than he did.

So if it’s a small gap, I’m may be fine with my 115 pound spring.

Technically it’ll make a 2.4% difference in leverage. Not noticeable. Scale up your spring rate accordingly. That’s where I’d start. I mean who told you to increase the spring rate in the first place?

And since you have money to burn why don’t you pony up and PAY a suspension tuner for their advice? Seems a better way to spend your money. You ask for advice on a forum you get what you pay for.

rac1ngsnak3 · Nov 6, 2021

Also if you think about it logically, spring rate contracts sag not ride height. You’re weight isn’t changing so why would you need to change spring rate???

also Extending you’re swingarm will minimally effect anti-wheelie. In fact, w your 30 years in Motorsport you should know that this extended swingarm is primarily to help drive by forcing the rear tire into the ground by increasing anti-squat. This wheelie-ing that you’re getting is due to novice riding technique and poor suspension setup.

Thanks, an to that last bit, I am also talking to a few suspension experts abs have queries out that I’m waiting for answers to with others, but as an Analyst by profession I know that tribal knowledge is also useful, and the tribe of Ducati owners abs racers here is a useful additional source of information, abs I use it as such.

In life, if you know what questions to ask that’s a good thing, because if you’re diligent enough you’ll find the answer to the questions you know to ask, but it’s the questions you DON’T know to ask that should keep you up at at night, because you don’t know what risks or opportunities that you aren’t even asking questions about.

I’ve learned a lot from members here, but perhaps the most useful thing is by asking these questions here and letting the conversation unfold I learn more questions to ask.

Knowing what questions to ask is more valuable than most answers.

Agreed to that last bit, but in my experience you there is rarely ONE BIG THING that solves a problem on high performance machines, it’s a bunch of little things working together the right way. This is one of those little adjustments that adds up with the suspension stuff I’ve already done, and the sport bike training I already booked.

So now you’re asking for our opinion (ie tribal knowledge) and when people say it’s not worth it/that you’re doing it wrong, you still call them a Karen??? That doesn’t make sense. You want opinions but then don’t want to hear the opinions you don’t agree with. I’ve seen this before…

What you need is either:

Vicati aka 650dweeb to source you a drag swingarm

Or you need the great and all knowing Mick to fab you up a rear ride height device since he’s the mastercraftsman

I’m actually flattered this ...... thinks I’m 650ib, I mean 650ib looks like a chill and humble dude. But I’m shorter & lighter. I am Vicati… but uh why are you still here is my question? Lol I mean “2.4% or 2.5% difference in leverage” almost made me puke, this mf really out here making up figures to pass off as “data” gtfoh clown you are the perfect example of clown emoji on iPhones… that’s how I picture you.. anyways get yourself an extended swing arm Karen or Kyle whatever you are and post when you have actual value to give, because this .... talk doesn’t make you more of a man and I think everyone could agree.

Also that’s not even 650ibs bike that’s someone else’s… there’s a company in the east coast that’s makes that super long swing arm for the V4.

RickD996 · Nov 6, 2021

What I would suggest Steven, is spend a lot of time riding the stock swingarm. Try all the different settings other people are trying. When you find a setting that suits your riding style (a base setting), and you are comfortable with the bike, can feel it moving, can predict it, feel connected to it, then fit the longer swingarm with the spring you have. Spend some time understanding it, and work forward from there.

What adjustments did Pierobon recommend with the swingarm?

Alkhater · Nov 6, 2021

Slightly off topic but the Streetfighter has 19mm longer wheelbase than the Panigale and the same rake, so I’m assuming the extra length is from the swingarm.

Can anyone confirm this?

If the SF swingarm is indeed longer then it might be a more affordable upgrade even though it’s not quite as long as the Pierobon.

SF swingarm is the same length, I've checked! I think it's just set differently in the swingarm hub from the factory.
