Ti Pistons for Brembo Caliper

Gecko,

Please check yourself into rehab. You my friend have a sickness.

Pretty soon your Panigale is gonna be able to fly away with the wind.

Side note, are you interested in adopting a 37yr old man?
 
I have the GP P4 32/36 (XA7G210/11) monoblock 100mm calipers on my 1299. They ship with the Ti pistons. Like the description states in the ad for the pistons your looking at "race only".
What does that mean. Not sure but i was told by TAW that these calipers require routine inspection and cleaning as they do not have the weatherproofing/contamination spec that the stock road calipers have. Not sure what that means but it makes sense. These calipers are meant to be cleaned between rounds not go 10,000 miles. I have the Staubli quick disconnect lines and I clean these things regularly. This takes minutes as I do not have to bleed anything so no big deal. In your case the pistons should be fine in the stock calipers but aside from a fractional weight savings, there would be no noticeable advantage. The Brembo billet rear caliper for the 1299 ($549.00) actually comes with aluminum pistons which are lighter than the Ti pistons in my P4-24 rear.On a side note these monoblocks with the T Rotors are insane and i do run them through a modded ABS and the performance is outstanding. If you have to have them, get them. We all love Ti.

You Sir must have an awesome bike! Love Staubli, company is near where I live.
What did you "mod" on your ABS? Thanks for sharing your thoughts.
I've seen on some Panigales that they placed Stahlbus valves instead of the OEM banjo bolts into the ABS unit to make sure that they completely can bleed the whole system. Does this make sense to you?
 
The ABS mod i believe has something to do with how the circuit modulates input pressure and feedback to the lever. The unit came from Bosh and was something they were working on at some point for a track application. I got it from a friend in EU. When i was building the bike i was not going to use ABS but ended up trying it out when this opportunity came up. I can tell you that the brake feel is much closer to a non ABS race set up than with the stock ABS pump. I have tried both on this bike with the same masters and calipers. On the front calipers I use the Staubli banjo fittings and quick release instead of the Staubli inline QR with a standard banjo. I also used the Staubli bleeders as well. Same set up on the rear caliper. On the ABS pump itself, i made a set of titanium banjos that are drilled to accept the Staubli bleeders. Very easy to make with a lathe. I have a zero loss system now that I can bleed effortlessly. I use the Brembo billet GP 19/18 MC and the Brembo billet GP rear MC. The rear is super cool as it has a built in res and bolts right up to the DC rear sets. I made a Ti piston rod for the rear MC as well. Obviously this is not the most cost effective setup. Between calipers, MC fittings and lines there is 8k in brakes but it does stop like nothing else and the ABS works exceptionally well. I have a set of ceramic rotors that i may try next week. The bike is just a project/concept bike. I wanted a WSBK that was reliable and ergonomically favorable and ran cool in traffic. It has accomplished all of those things.

Very cool. Didn't know that Staubli also makes bleeders.
Want to change the rear brake pump with integrated res as well, love the design. I've seen them first on Suter bikes, very clean design. You are going to love the rotors, bike feels like a bicycle, they massively change the motorcycle's behaviour!
 
A piston is just a piston. Its only function is to accept force from one side and transfer it to the other. Personally, I see it as a huge waste of money for something that will not only accomplish exactly nothing, but will not save any weight because they are too small, and it cant even be seen. So not only will you not be able to notice/see/feel any difference, nobody else will either because it is hidden.

I am really trying my best, but I honestly cannot think of a single thing that would be a bigger waste of money on the entire motorcycle.

If you were talking about changing the whole caliper, then that would be something worth discussing.

But of course, things like "waste" and "worth" are relative terms. To each their own. It is your bike, go for it. :)

Ti has much different thermodynamic properties than aluminum . They are also drilled creating more surface area and ventilation. Less heat at the piston = less heat in the calipers and hydraulic system. = better and more consistent braking. Also the low friction coating lets them move more freely reducing drag.

Definitely not just bling. There are much worse ways to spend your money.
Like the Pro-Ti caliper bolts I just bought. [emoji58]
 
Do you have back-to-back braking data logs to support the claim of "better and more consistent braking"?

Or can you prove how much lower the brake fluid temperature remains?

All of those things sound great on paper, but I want to hear somebody say "I was braking into T10 at the 4...I swapped the Pistons to Ti and now I brake at the 3".

Unless somebody can provide tangible data proving that after keeping everything else the same, and ONLY changing the Pistons, they were able to brake deeper/better/etc...then I am calling it just bling.

But as always, that is just my opinion.

Have to agree with Chaotic on this one. Yes with precise instrumentation, thermodynamic properties are measurable between materials and certain materials posses favorable characteristics for certain things. That being said, not a chance in heck your going to notice anything humanly discernible here. I do have the Ti pistons in my calipers as that is what they shipped with. In my case, I am not that smart to shy away from doing goofy things with money probably spent more usefully elsewhere.
 
If I remember correctly Gecko has a friend who installed Ti pistons in his M50's and had a wholesome and measurable improvement. Gecko?

Yep, but he did it on his Multistrada :( (he made this elephant 25kg lighter!)
And for his R he probably goes endodoc's route. I think that Chaotic and endodoc have good points on here.
(BTW this guy's next step to make his R really lighter is to install CF forks! If he is able to homologate them, I'll get them for my SL, but from my expierience this wont happen until end of this year).


I tend to classify these pistons as "invisible bling". It makes your bike marginally lighter and will not be easyly detected by police and gov. bike inspectors. But most probably no change to braking behaviour. And pricey :(

Drat I thought you recommended it to me as an alternative when I complained about the feeble braking power of the m50's and wanted to change the calipers?

:eek:
Did I recommend it? I can't really remember this chat. But I'm pretty sure that I would have said that it might improve braking behaviour as said in the ad.

First time I saw such pistons in reality was in 2015. I never though about them before.
I colleague wanted to produce them, but you know, most things these people say is blabla.

Anyway, I contacted the Multistrada guy and asked him about the pistons and he was not sooo excited anymore, basically because of the price.
 
I totally agree
For us mere mortals its a negligible difference.

If they were $120 for a set + spec seals I'd buy them [emoji106]
