Default 996/8 progressive/linear link

Did the 996/8 race bikes use a linear linkage arm for the shock or was a the stock progressive linkage used?

Is there an after market item?

cheers

Donīt really know, but Iīd say the 749R stock linear rocker would fit.

Getting the rear link is only 1/2 the battle. The valving in the shock is also matched for that linear link. You'd also need the 749R's ride height adjuster because its a different length then the stock unit. So 1) Link, 2) ride height adjuster, 3) Some sort of shock that has the proper valving.

Lets see if Dan Kyle responds to this thread... I'd be interested to see if he has a solution.

I don't know if you can buy an aftermarket linkage by itself, but I know Motowheels still sells the Marchesini long swingarm that comes with a flat-rate linkage - with that linkage, you can use the stock ride height rod, though you'll want to shave some thickness off the lock nuts. You need a much stiffer spring as well as revalving. IMO the long swingarm by itself is a step backwards unless you also go to the 23.5 degree rake with aftermarket clamps having less offset (27-29 mm works well), so this is an expensive route and not worthwhile unless you're tracking the bike all the time at a race pace.

That answers my original question Jeff. The race bikes had the longer swingarm with a linear linkage.

I might have a play with this and I understand I need to change a lot of other things for it to work properly.

I already have short offset triples and other goodies. I'm always looking for the next thing to tweak, as you do.

cheers

Should be able to get the link from Ram or Febur who make most of the long mag arms for importers. Febur makes the Marchesini arm.

Ohh, I was wondering where that forum went! LOL

It seems to me, the biggest difference between ducati.ms and speedzilla is; the guys here are usually crazy racer types! "Ohh, I wanna spend $20k on my 749R so it can be a corse bike" no big deal right? Do it in a weekend? LOL

What I was just wondering - 998cruiser or DesmoDuke (your avatar gave you away ), do you have any rear end problems? Just thinking out loud, because why would you change the stock setup if you donīt have a problem... just for the sake of doing it?

Good question Ben!

There are a few reasons for doing it, I'm not sure any of them make sense. That's why I started to dig around.

My shock is due service/rebuild anyway

Just as the front end didn't have a problem, yet I changed the offset of it. Just to see if it improved things, and it did.

Same thing with the rear. It's not broken or bad. But if I hear that the pro's are riding with linear linkage, I'm tempted to try it.

Do I need it? Well, that's irrelevant. I don't need a Ducati Superbike in the first place really. I do it for fun, tweak and ride, tweak and ride, just like most of us I'd imagine.

Now, here's how I wish I could ride my 998:

Cheers guys! I appreciate your help and thoughts!

ps. My girlfriend is waiting for me to buy us a dishwasher. Linkage or a dishwasher? What's wrong with takeaways?

I see, that reason is good enough mate.
My suspension guy always rants at the linear linkage because Öhlins had so many problems with it during the Supersport season when Ducati raced the 749R. But other people here said good things about it. I donīt know if it makes such a big difference, havenīt tried it.

As for the dishwasher... doesnīt she have two hands? Sexist, I know...

ok, that's good to know. Maybe I'll lower it on the (bike) priority list.

cheers bro

Default Aftermarket linkage arms

I have seen two types of aftermarket linkage arms, one hole where the ride height rod bolts into and an arm with two holes, and I have seen both holes being used [not at the same time] so the question is, is linear when all three bolt holes line up [spring,frame,rod ] and whats the second hole for?

Like this one:

A part from 998rs. Probably what I'm after. Who knows what else needs to be changed for this to work.

I just got back from my dealer, they've got a mag corse arm on the shelf no longer used. Hmmm...

The mag. swingarm is a good thing, it goes with the offset triples you have got, but there's a couple of questions you need to ask, does it come with the excentric? if it does what size axle does it take? does it come with a linkage arm and finally you will need to get your shock revalved and spring changed, I went through that exercise two years ago
