Looks like a standard rod, but its a different color.It does have Pankl bolts. After identifying the rod I'll let you know what it was in. You may be surprised, or may not. It has a 20mm little end.

by the numbers on them and where they are placed i'd say they're early carrillo rods. they supply the same type of bolt as used on pankls too. as far as what they're out of? by your other post i'll guess at a 900SS, but they're definitely not std fitment.

Sorry there Paul, not Corrillo, nor 900ss. Anyone?

Oh we do care griff, we just haven't got a f***ing clue!!!!!!!! 😁

Actually they are a set of............ Arrrrrrrrr...arrr....gh!
Actually I have no idea what so ever. Thats why I put them up.
They were inside an SP4. Carrillo have denied owning them (These are corrillos image 007 for want of a corrillo rod if you have never seen them). No Pankl name on rod, yet curiously pankl bolts. The color is different ego some coating I think. There is white visible where there has been a bit of biff going on. White is Ti or Al in the corrosion dept. No I don't know the weight. Or is it surface prep material? The beveled edge with the number on it, is clean. Standard rod is rougher.
If it is corrosion. My thinking in its warped way, is that they may be "Ducati thinking" to solve a problem. Like the eye rod ends on 90-91 rear suspension hoop's. They got spooked with the early tricolor swing arm issue, and got special eye rod ends made. From a little Switz village no less, that makes internal gizmo's for watches and worlds most expensive eye rod ends.
The SP5 went to 21mm gudgeon pin because something was breaking.
I suggest they are specials made by the same company that makes the standard rod.
Any one know the company name that makes the standard rod, so I can email them?

Hi Griff,
I'm also interested but haven't a clue, which's why I've not answered.
If I don't know for sure I'll never bullshit or waffle!
Spike's posted pic's of his Pankle's which look very similar, but early SP's had steel Pankle's, I think/believe the SP(4)S had Ti' rods with 20mm smallends.
Stop being a little tease and find out the weight and put a magnet to them!
As I've said before I'd choose Carrillo's (I'm a big fan) before using something with an uncertain history.

Well there in lies the problem. If I get the guy to put a magnet or weight them then he'll know and I won't get them at what I could say is a rudely cheap price.

haha, so they're not yours yet huh?
i'm with steve, i'd definitely buy new carrillos before using something with an unknown history. i fitted carrillos in my engine and they came with the same bolts, so again, that style isn't exclusive to pankl, and from the limited pic i saw the number (assuming it's a part number???) in the same place as the carrillo ones, though carrillo now use a computer type punch to precisely mark their rods. the ones in your pic look hand engraved almost.

The number is the rod/cap reference number, not a part number. The big thing is price. The bolts cost 125 euro each ( Why, I don't know I'm looking into that. From Porche, 10mm pankl bolts are $30 each), you can buy new carrillos from the US for that.
They are mine if I want them.

Hi Griff,
If they're indeed Ti Pankl's then the bolts prices are outrageous, but if they're steel Pankl's the prices aren't that bad...
Steve Wynne once told me "Don't buy new bolts Steve, even new bolts can stretch beyond tollerances, best try the ones you've got before buying new ones they can be used 2 or 3 times".

Hi Steve I'm emailing Pankl, Unbrako and a bloke that was heavily involved in the early 90's Ducati Superbike race team here. I will find the answer eventually. I like a good mystery.
As cost is more relevant than wank factor, I'll make my D when I have all the info. One has to be rational when rebuilding an engine as you well know!
Its been interesting. Did you know Ti rods have twice the fatigue life of steel rods. Some index that I found says 12.8 Ti and 5.6 for steel. Better fuel economy (Rotational/liner motion mass stuff), power and reduced bearing loading. There is a push to get all cars fitted up to reduce fuel consumption, but production cost remains the big stopper. Although they are now experimenting with new Ti alloys in order to reduce the cost.
Corrillo has an excellent page on the subject of TI rod development requirements, which goes into surface preperation.
All this has made me remember a program I saw on F1 cars. Their tiny pistons were exerting 11 tons psi on the rod neck at max rpm. Amazing!
Personally I don't think the rods in question will be Ti, but you never know hey!

Hi Griff, The Rods in image 001 look identical to those removed from my 94Model year 888 Strada, even down to the small oil hole under the little end. The only marking on my Rods was adjacent one of the bolts and would appear to be the rod weight (presumably to allow Ducati to pair them at assembly). They are Steel and weight approx 553g each. Hope this helps - I can post a picture if that would help.
On a slightly different note, how do I add an avatar?
Cheers, Ian.

Were the rods the same strange color? As they look very similar to standard H section steel rods. Might as well stick up a pic.

I forwarded the pic of the rods to my friend Mark who has some experience with Ti rods in his Corse bikes and he says they look like Ti, with the bolts that can be used 3 times.
griff851
I got in contact with the Captain of the "Dark Star". He seems to think they may be Pankl steel H section race rods, used before they went to Titanium.
I couldn't help myself curiosity got to me and have I sacrificed a possible bargain to ask the guy selling them to do the magnet thing. If they are steel either race or 94 888 strada (which could be one in the same), I wouldn't be using them anyway. Who knows what hell they have been through. Titaniums I might consider. Guess I have to negotiate that one now.
Pankl steel 553grams
