1199R Brembo rcs19 compatibility

I'm extremely excited about this it's funny I actually forgot that I am the original poster

Just to add a data point, there is also the Accossato PRS master that is currently available in 16mm piston size, with three adjustable pivot positions. It goes from 16X17 to 16X18 to 16X19mm, where Brembo usually has 18 & 20mm pivot locations.

Now that last year there was an announcement for the brembo rcs17 which are compatible with the m50 monobloc calipers on our bike I'm wondering when will they release!!!!!!!!! i held up purchasing the dp levers and going this route because everyone swears by the brembo rcs16-19 so i want in on this! i know that our current master cylinders are good but i want better!!!!

quack.. if you want to top your braking game, i think the stock master and calipers are a very hard to beat package..

i will take many thousands of intense riding miles ( possible trackside?) jut to get the feel of them . It is this feel and experience that will make those brakes yours to understand , know and trust.

i never really understood the concept for changing gears on your master brake cylinder.

i would really like to know how many people get out in the morning, look at the sky, check the road temp and then decide : "oh me, this is definetly a 16x17 morning" and then switch midday as the temp rises... we're relying on abs to keep them stock ones in check and not to stoppie each time we just look at them...

Rcs 17 will not be next year! It's this year sometime in may is expected delivery

Il keep you guys posted

Said the guy with 10,000.00 in Brembo brakes!!!!!! Lol thanks for the advice Kope also are you saying that the abs won't work if we switch the stock master cylinders ?

I know you will know fahad.... Keep me posted

What a perfect illustration as to why this forum is so great. An incredible amount of pertinent information supplied by people with actual experience. That is why this forum is always an active tab on my Mac. Good job everyone.

ABS will still work regardless of cylinder. . I think he meant the abs valve is there to keep the brakes from locking the wheels up. ..

Honestly, I think the people who "swear" by the RCS are just ones who want to enjoy their purchase. . it's really not /that/ great of a product. They have 3 versions of their product that are better than that (unfortunately not for the m50 caliper cylinder size) RCS line. Its just that the RCS line is the catchy one with the adjustable cylinder fulcrum point.. But the forged, the billet and the forged billet GP ones are all better than the RCS. And their next level up (while not adjustable) is only marginally more expensive than the rcs line but a better product overall.

I had started down that road and thanks to the forum I was able to return the RCS 19s before installation.

Any input on the best levers for the standard master cylinder? I have a broken tip and have the DP levers on order but way back ordered. Been over a month now and still no word?

lol!

the story is that you either go all the way or leave it... i think i'd prefer the HK320mm supersport + P4-100MMbillet + billet19x20 master combo over the stock setup ... but putting only a variable master won't change a lot if anything at all...

and changing it all does not come cheap... and het stock are known to be the best in the business on any machine for the moment...

its like you said: whey then spend 400 usd?

This! Finally some sense and understanding of the product line.

Any billet MC is going to be better than any of the RCS series. I would rather get a Performance Technology (PT - made in Italy) billet MC for the same cost of a Brembo RCS cast MC. Oh wait - that's what I did on my race bike. Accossato is a good choice too. Brembo makes great products, but if you're serious about performance for the dollar, there are other options.

It really depends on what the intended uses are. The forged are awsome like most high end race performance parts, but not so much on the street. If you have a dedicated track bike the forged GP, M/C and higher end Brembo caliper would be the way to go. If you mostly ride the street and track days in between the RCS would be the way to go. The adjustability allows hard bite that you need on the street and a softer bite for the track thats why they are so popular.

are you sure you meant what you wrote ? Most people who use the 19x 18/20, have it set 18 for the street and 20 for the track i believe. Which means its "tighter with less play" on the 20 setting and softer at the 18 setting for the street. .. . which is exactly opposite of what you wrote.

I was thinking the same thing but obviously he meant it backwards .... Good catch

Not so sure. . . an explanation was given to justify the position which is exactly opposite of what track day riders generally use/have. . if it was just a number - then possibly, but the reasoning is backwards.

Noooo!

Brembos quick rule of thumb is "19x18 for track riding, and the 19x20 for street use".

"The 19x18 cylinder has better modulation more precise, given its marginally longer operating travel when compared to the 19x20, which on the other hand offers a slightly quicker response.

You dont want it to react quick while racing/track. You want it to react quicker on the street. you dont want someone rear ending you while racing/track day.
you want to beable to feel your braking not pull the lever slightly and almost come to a complete stop.
There is really no reason for abrupt braking on the track as you would on the street.

This is all about personal preference, I've used the billet racing 19x20 master on my last 5 Ducati track bikes (JeffD is correct, the billet racing products are better in high performance applications than the RCS stuff), and I prefer it over 19x18. The difference is really whether you prefer to modulate your braking more through lever TRAVEL or lever PRESSURE. I prefer pressure, and running the lever really close to the bar, so I use 19x20. Personally, I think the RCS product line is kind of dumb, who wants their brakes to respond differently based upon an adjustment? Get your brakes set up how you like them, get to know them intimately, and then leave them that way so you always know what to expect from them in any conditions.

P.S. - 17RCS for the 1199 is looking more like late May/early June for them to actually arrive in the U.S.

Installing the brembo RCS will give you a more solid and stiff feel at the brake lever. You will also get a tremendous improvement in braking.

No offense intended, but .........

A more solid and stiff feel at the brake lever is true.......if by that you mean as wooden as the wheel on a conestoga wagon. The part about a "tremendous improvement in braking" is nonsense.

The calipers and master work as a system. You can reach the point of locking the wheel with less travel by using a larger master piston (which is what you'd be doing with the RCS 19 in lieu of the OE 16) but the force needed to stop the bike is only as much as the tire's contact patch can tolerate.....and you can already get there easily with the OE setup. In fact the larger end area of the 19mm master means it actually takes more lever effort to reach that point, but less travel, compounding the resultant lack of feel. What you're doing is getting to the ultimate stopping force with about 1/3 less travel of the lever (the approximate ratio of master cylinder piston area) but 1/3 more required effort. That extra travel and lower effort are what yields what we call "feel".

This is compounded by the lever pivot arrangement, but since I don't recall the lever ratios I won't throw that into the mix. It could make this a bit worse or alleviate it slightly, depending on geometry.

Brembo are supposed to be working toward supplying an RCS 17 for use with Panigale, but I haven't seen one, yet. Why you'd want one is beyond me. I can stand my Pani on its nose with a single finger and modulate anywhere I want short of that for trailing. What more could you want?

I'd say JarelJ's experience with five other Ducatis is somewhat moot here, too, as the new calipers employ smaller pistons than earlier models, changing the arrangement required for a proper balance of power and feel.

All are correct in saying the billet bits are better than RCS, and I second the Accossato recommendation....partially because I'm a dealer for them, I guess. That said, spend your money on hookers and blow, because the brakes on your Pani are almost certainly already better than you are.

Don't "upgrade" brakes because you heard it'd make your riding experience better. Know what you're buying and really upgrade, though the OE arrangement is hard to beat for street riding, IMHO.

I some what agree and disagree with your statement. That is like saying who needs ABS? If you are an advance rider on the track, going 19x20 is OK but for the average rider who needs ABS on the street would probably want 19x18 for the track. I agree with you that everyone needs to get intimate with their brakes but everyone is not advanced enough when a panic situation occurs hence ABS. I prefer 19x20 and with no ABS for track and street myself but I wouldnt call adjustment to brakes and ABS to assist the beginners to intermediate dumb. I agree that the RCS is nowhere near the high performance M/C that brembo make. They make M/C's in the $2K range. but the RCS is a compromise between street and track IMHO.
