I guess their dainty weak fingers can handle a real master cylinder.

I love this whole "I can feel the difference of 16 vs 17 mm, forged vs billet." Literally placebo effect. Also, this different feel could come down to performing a fresh fill/bleed on the new system and not your fancy new MC. It's madness but also fun to ridicule. What a train wreck.

As much fun as it’s been learning what not to do from our little trackday hero, back to the master cylinder.

It’s interesting that they would put a 16mm piston master cylinder with 30mm piston brake calipers. I thought Brembo generally recommend 17mm for these brake callipers?

I’d guess a 17mm master cylinder would be a worthwhile upgrade, but then I’d be into changing switchgear as well.

The switchgear is plug and play so it’s no difficult.

I’m coming to the conclusion that you’re just a troll. I doubt you’ve tried them but you’ve got an opinion nonetheless.

Personally, I’d want to try something before ridiculing it. If I tried it and didn’t feel a difference then it would remain a possibility that others feel a difference that I cannot feel, so I still wouldn’t ridicule people who came to a different conclusion.

Your use of the word ‘fancy’ might indicate that it’s just that green-eyed monster showing it’s face yet again.

Keep trolling though. 🤷‍♂️

Maybe I’ll consider trying it. Lots of people seem to do so.

The MCS master cylinder on my SP2 is 16/19-21 and I’ve had it set on 20. I hadn’t tried 21 to see if I felt any difference.

I do find it interesting that Brembo recommend 17 for a 30mm piston but Ducati use 16.

The 16 is more compliant for street riding, less chance of a squid panic braking mid-turn and going down…I personally think that’s why they build some slop into the stock throttle too, makes the bike less jumpy if you are holding the throttle in a death grip if you hit a bump…neither good for track riding and precision braking and throttle application.
 
Get the 17 RCS Corsa Corta and the Dukabike switches that bolt to back of the brake MC, then adjust the settings on the 17 Corsa Corta to ‘R’ which will get you the 20 throw you are use to, not counting the brake bleeding it’s literally a 10 or 15 minute job that’s super easy.

I won’t really use the R on the street. I guess that makes sense.

Sounds good. Maybe this is a worthwhile change for track use. I’ve seen switches that replace the housing on the throttle that look quite good.

And while you are at it get the JetPrime quick turn throttle, another plug and play easy upgrade that feels good 😂😂😂

The throttle on the 2023 R has zero slop in it and has a shorter throw than the one on my SP2. Apparently it feels the same as the Domino unit, so I’m not sure it really needs to be changed or that there would be any real benefit.

I’m not sure you can feel a difference between billet versus cast, I’m told the only reason billet is better is for R&D, meaning you can more easily change up a billet part than a forged part cast from a mold.

However, 100% you can feel the difference between a 16mm MC and a 17mm MC. Surely you understand the basics of mechanical leverage and fluid compression etc. it absolutely is a noticeable difference.

With all due respect a lot of your posts about stuff to do with these bikes seems to be imbued with a huge amount of confirmation bias, where your opinions are shaped by an over riding general laziness at looking deeply enough into anything that would suggest doing anything that would require you to put the tiniest bit of effort into the bike lol.

Your default position seems to be “naw you don’t need that and in fact it’s useless to do” but it really seems to be an internal dialogue of you telling yourself ‘I don’t feel like bothering with that’ 😂😂😂

That makes sense.

It feels like I might be going shopping… maybe before I’ve even tried the OEM stuff.

Bored waiting for warm tarmac…
 
Spooky, what you need is some carbon discs, adjustable triple, and an extended swingarm, and factory Aruba.it sticker pack. And then add in some skills and talent while you’re at it haha
