Brembo CNC 19x18 (XR01171) master front brake cylinder

Does anyone use this Brembo brake cylinder? Any opinions?I have the RCS and I am looking for even better feeling. I have talked with Brembo technicians and have been told it is an upgrade from my current setup (M4 calipers).

@the_gooch runs some form of Brembo CNC MC. I would PM him. He doesn't log on as much as he once did.

The RCS is garbage compared to the Brembo XR01171. The newest RCS Corsa Corta is much better than the old but neither are true racing parts like the XR01171. I am a Brembo dealer now in case you have issues sourcing anything.

Now if you wanna be a baller: XA7G7G0 I HIGHLY recommend CASTROL SRF fluid...

Well MotoGP staff is really nice but also very expensive. I always use Castrol SRF because I also think is THE best brake fluid that we can buy.
Beside been a dealer do you have personal experience with the XR01171?

Yes. I had one on my bike then foolishly sold it. Will be getting either another XR0 or XA7 here shortly.

I am not 100% sure on the new RCS but the old one is not even serviceable. Throw away piece. The build quality and feel through the lever on the XR0 puts the RCS to shame.

The RCS is really a street master. The changing ratio is a gimmick in my eyes. I changed it once to see what I preferred and it has stayed at 19x18 ever since.

So I gotta ask, what does one of those fancy things cost?

I had/have the billet/XA one on both RR/R1 and it's the way to go. RCS is garbage (feel, serviceability, quality, etc...) compared to XA.

$700-750 new depending where you get XA. Can be had used or ordered from EU for $600-700.

There's always the cheaper fixed ratio version, but I don't know if it's internally just as shite as the RCS or not. It feels good though.

It also definitely comes with a folding lever version:

^ That's forged MC. It's a step up from RCS, good option for a mostly street bike with some track days. Costs about the same as RCS.
