My current bike is a Triumph 765 RS that has the Brembo M50 with the Brembo (excuse me if I get this wrong) MC that has 17,19,20. Not sure if this is an increasing Master cylinder piston size or a pivot ratio. I am looking at upgrading to a 17-19 Honda cbr1000 rr SP1 that It seems has the same Brembo M50 calipers. I go through stock brembo pads in 10k KM just being ridden in canyons on the Triumph. When I upgrade to the SP1 with more weight and HP I fear with the same brake setup I will be underwhelmed. Overheating the fluid has not been a concern of mine yet as I run high temp Brake fluid and the pads are not crumbling or indicating overheating. What would be the next step up in brake performance to get more stopping power out of the 17-19 SP1? I already run the Master cylinder on the Triumph set at 20 as it takes less effort to get the power I'm looking for though losing a bit of feel over 19. The ideal way is to buy a 2020 S1 with the Styleema but those are more than twice as expensive here in Thailand.

Thanks in advance.
I was mistaken in my previous statement. The Brembo calipers that come with the bike are not true Brembo M4's. They are basically an OEM caliper with Brembo logo as far as I can tell. Same piston size as OEM.

To be 100% accurate in the description, they are simply the very same Brembo calipers as those fitted to the 2014, 2015 and 2016 SPs.

So as much Brembo ;lineage as folks were willing to give the 14/15/16 SP brakes, these are the same.
The Nissin master cylinder of course is unique to the SC77 range.
To be accurate:
Calipers are brembo , were made on honda specs in brembo

and:
sc57 , sc59 , sc82 not SP all came with 17,5 master , sc 82 sp got a 16 mm

Welcome, and as you know most Triumphs have very good brake set ups on them from the get go (superior to the SP 1 in everyway)
On the Sp 1, to start there is not much weight difference between the bikes. as for calipers it has a semi M4 caliper.. think 2011 675R, but instead of it having the (4) 34mm pistons like it should, these have a (2) 32mm (2) 34 piston in them, and they are paired with rubber lines and not so great brake master. The system can be better, but you need to bypass the abs, and do stainless lines at a minimum. Not sure why but like many people no matter what they do the lever never feels rock solid if the ABS is in the loop. I have talked to quite a few now, and done plenty of modding with mine, only thing left to try is pulling the fuse before i bypass the ABS.

The caliper can work fine
a Brembo 19x18/20 RCS will be better than what is on it
Stainless lines..
this will be somewhat close to what your used to with the triumph.
Thank you so much for the detailed responses from yourself and others. Darn I was hoping the 17-19 SP1 had the M50. In the switch to the Honda I actually don't want to lose any braking capacity at all. Rather than paying the equivalent of $15k more dollars for a new 2020 SP1 with the Styleema calipers what would i need to purchase to make the brakes on a 17-19 S1 at least as good than the M50's on my Triumph 765 RS? I can start a new thread if that is preferred.

get some brembo gp4rs with ZCOO pads and a rcs or rsc corsacorta master .
if you do not know which size of master cylinder you can calculate the ratio and than decide which kind of response at the brake lever you will have.

There is loads of options, don't let brakes dictate a purchase of the bike. if you bypass the ABS, slap on stainless lines then you can decide from there where you may want to go.. you do not hear of people who who bypassed it and changed the lines complaining.

Just putting it out there and as derchef said, if you really like the M50 calipers, then they make the 108mm version of them, the GP4RS ( i have them on my 10R) those with stainless lines and a 17 corsa corta RCS, and brembo hpk rotors.. The combo has tons of feel and more than enough power to get the back wheel off the ground with a passenger.

Correct - which is why as replacement parts from Honda they all have the same part number for all those years of the SP. The calipers are the same for 14/15/16/17/18/19 SPs.

Ok this answers the brake queries for me thank you. I shall do as derchef and jdgun suggested and get the gp4rs calipers as the M50's I love on the Triumph I have, combined with the Brembo RCS 19. Thank you guys.

That is one way to do it...I think the oem calipers should provide you what you want, if you bypass the ABS, and upgrade the lines and master. wish i could give you my no BS report, but waiting on parts to show up, and now snow is coming in over the weekend.

I’m late to the story .. but to add
My SC77 runs with the forged master cylinder 19x18, i think, direct lines to the callipers. I am on GP4 cailpers and Brembo t bolt discs.

The standard callipers are same as 2015 SP, but also same spec as used by Suzuki on 750, 1000 and 1300. It is a straight fit to the 2011-2015 Kawasaki ZX10 as well.. 108mm caliper… where it is a nice upgrade for the ZX10 is the piston diameter, Brembo being 30mm while the stock was 23mm
