1199/1299 Titanium swing arm pivot bolt report (photo)

If you looking to replace the steel units with the Titanium pieces from Podium this is the wear after about 3k miles. Pretty much what I expected. I replaced it. Probably could have gone a bit longer.

So the titanium ones needs replacing every 3k? Or did I read it wrong?

.... . I've got them but did not install them. I wanted to TiN or DLC coat them first.

Anyway PodiumRacing made a big mess with these parts. These do only fit in non-adjustable swingarms, but their kit also includes the inner big screws which are a Ti replacement for the adjustable swingarm.

Thanks for this information!

Titanium is a nice metal for many things, but its main attributes are tensile strength and corrosion resistance, but it is not the hardest of metals, if I recall correctly the Rockwell hardness of titanium gr5 is in the high 30's, while steel alloys are usually between 50 and up into the 70's.

So placing titanium in a situation where it is moving against a harder metal, the titanium piece will wear much faster, which I guess is what we are seeing here.

I am sure an engineer can provide a better explanation for this than I have here

Sorry my bad. I know Titanium does not make a particularly good bearing surface compared to hardened steel so I had planned on pulling the side that rides on the needle bearings at some interval to see if any galling had taken place. I pulled this one at 3000 miles and this is the condition. There was slight pitting from the hardened needle bearings which one would suspect. Could I have reused this without issue? so the 3000 mile reference is just random. I used Ti lube on the threads and synthetic high pressure bearing grease on the bearing surface. Maybe a coating would make a difference I don't know. Now the bad news. When I pulled this I had just ordered a Ti oil fill cap from Podium. When I went to install it, for some reason it did not fit so I decided to chuck it up in the lathe and make a spacer out of it. To my surprise, it cut like mild steel it was very soft. I immediately removed the other swing arm pin. I asked Podium to provide a material sheet for their Titanium. They did not. I have since made my own Ti pivot bolts for the swingarm out of qualified material. Note to self. Do not use Ti in critical applications if you do not know the integrity of the material. That was just stupid of me as I knew better. All the structural Ti on my bike (and there is a lot of it) I get from the aerospace supplier to Airbus. Would I use Podium fasteners on my bike? Sure and I do but not for anything critical nor would I use Ti hardware from any other unverified source that would be used in a critical application. Then again Ducati has some of the shittiest fasteners in the industry so who knows. Just my 2 cents discounted to 1 cent as I have a wife.

Mordor. Yes you are correct. There are many grades of Ti. I have not done a metallurgical test or a Rockwell test on these components but the face that the material is not traceable means these could easily be Chinese as I'm sure most of the stuff is especially metric. I have a lot of Poggipolini fasteners which I know are good quality but when I buy through Aerospace Supply, I get a pile of certification material. I think the ProTi products are good as well although again I don't know anyone who has ever seen any documentation on their materials.

Thanks for the info. What is the weight difference between OEM and this piece ?

At least PodiumRacing provides us loonatics with fasteners for a reasonable price!
I used them all over on my SL, and I am pretty happy. On my race bike I went for ProTi. Better quality (forged), but they do not cover the variety of bolt designs used on the Panigale

@endodoc: coating does the trick . But expensive
Did it on some parts and it solved all wearing problems.

Could you clarify which part of the oil filler cap system from Podium you put in the lathe, as from both descriptions (the $26 version and the "titanium" $32 version) on their ebay page states that the oil filler cap is machined from 6061-T6 aluminium and on the "titanium version" the removable bracket is Titanium.

From reading the ebay page on the oil filler caps,I believe the main cap that screws into the oil hole in the engine block is aluminium, while when I first saw the ad on ebay I thought the whole thing was titanium, so I guess one should always read through the material thoroughly.

And I have also bought quite a few screws and stuff from Podium and been very happy, but have stayed away from load bearing items like the pivot pins

And keep up the excellent work with testing and sharing the info, I greatly appreciate the new information we get from you

It was a one piece Titanium oil filler cap. I still have whats left of it somewhere. I bought a bunch of stuff from them as well and its fine but again its not load bearing stuff and i have not tested anything else from them or any other mfg but i could. I made the new units out of documented 6AL-4V G5. As far as weight goes i really dont know. Lighter for sure but i was looking for a higher quality fastener as I am not a big fan of the stock hardware. I was not paying much attention to the weight.

IMHO if you have a milling machine near to you, this is the best solution for a Ti oil filler cap:

It's heavier than any aluminium cap, but undestructible!

I received a handful of these from Yoshimura so I went with it.
