List of Bolt-On Front Brake Mods
Has anyone ever compiled a list of Calipers and Master Cylinders that are a simple bolt-on performance upgrade for the SH? I see a lot of individual threads and posts but no comprehensive list (make/model/year). If there is no such list would this thread be a good place to start one? Sort of a one stop shopping spot for searchers?

man awesome idea! i'd love to upgrade my fronts but not sure what will work with what from what years what needs to be trimmed to fit what works best...

GSXR calipers and master cylinders
I am fixin to do a pair of 2001 GSXR 1000 calipers with a 5/8 bore master cylinder from a 97 GSXR 750 (6 pot). I will check the fitment for the 97 calipers too. Will post results here.

come on guys i know there is a ton of knowledge on here...help the semi tool challenged out here! one quick question.
F4i 600RR RC51
GSXR
KAW
years? please!
lets say that i find a master and calipers that will work and i'm all set to put em on. will my goodridge braided lines work on the transplanted master/calipers? thanks

I don't know about GSX-Rs except for the 2000-2001 GSX-R 1000. Those are a direct bolt-on.
The F4, F4i, 600RR, RC51, 929RR, 954RR calipers are all externally identical, and they need slight grinding to clear the mounting bracket on the VTR fork leg. Other than that, they bolt on and work quite well. The caliper piston and master cylinder sizes vary from model to model and year to year. Here is a little chart I put together awhile back with all the data. I also believe the 919 calipers and maybe some others will fit, but I haven't really looked into it.
2003-2004 CBR600RR mc 11/16” (17.4625 mm)
caliper pistons 32mm/30mm
2000-2001 CBR929RR mc 19mm
caliper pistons 34mm/30mm
2002-2003 CBR954RR mc 11/16” (17.4625 mm)
caliper pistons 32mm/30mm
2000-2001 RC51 mc 19mm
caliper pistons 34mm/32mm
2002-present RC51 mc 11/16” (17.4625 mm)
caliper pistons 32mm/30mm
1999-Present CBR600F4(i) mc 5/8” (15.87mm)
caliper pistons 34mm/32mm

I have RC51 calipers and MC but I don't remember what years. The difference in braking power and feel is tremendous and a must if you want to go fast...or actually..go slow, after going fast....anyway,
I am now fitting up my 954 front with USD forks and 330mm rotors. Talk about braking! I will use the RC calipers but may sell my MC. I don't like the look nor understand the need for, the remote reservoir. It is ugly, easily tampered with, and unnecessary.
My options are a lever/mc combo with integral reservoir from a late 80s/90s bike. My question is.....the RC mc has a 19mm piston, which is 3/4". The ones with integral reservoirs are all 5/8ths. Is this going to make for a harder feel or softer? Thinking out loud goes like this: smaller piston=more leverage but less fluid moved. Larger piston=less leverage (like I need it with what I'm runnin')but more fluid movement meaning a harder feel.
Anyone still with me? zzzzzzzzzzzzzzzzzzz ok fine.

I have a 954 front end on my Super Hawk. Currently I have 600RR brakes, both mc and calipers, which are identical in size to the 954 pieces. Braking is excellent, but I thought it was even better when I had the F4i setup on there, which gives a little more braking pressure for a given amount of pressure at the lever.
Redman,
The reason for remote reservoirs is so that in the event of a crash the remote reservoir can be replaced without having to replace the entire mc assembly. If you crash with one of the integrated assemblies, usually you have to trash the entire mc and get a new one instead of just replacing the reservoir. At least that's the idea. I do agree that the integrated ones look slicker.

Cool, thanks Killer. I'll go with the integral 5/8ths. I'll do the same with the clutch....yes, for looks. If "they" were so concerned with aftercrash fixability, why didn't they design-in sliders?
So...who wants to buy my perfect RC51 19mm MC with new lever?
Yes Greg, I'll post in the Classifieds.
BTW, thanks for all your work and help here...you're the bestest..;-)
Also btw...RT says my GoldValves are correct and will swap right over from my VTR forks to my new 954USD forks! How yummy is that? Same stack and everything!

ok lets say i do this...find some F4i calipers for a good price modded for a hawk already, i look to a 600RR, 929, 954, RC51 or a F4i for a master bolt it all up to my goodridge braided lines and have awesome breaking power right? one more quick question, my Pazzo lever most likely will not work with the new master will it?

Some will work better than others with the F4i calipers, but they will all probably work OK. Check the specs I posted earlier in the thread. You want a simple answer, but it just doesn't work that way.
If you Pazzo lever is for the stock VTR mc it will work with the F4i mc. All the other master cylinders take a different lever.

I'm running a 600rr Master, f4i calipers, stainless lines & Galfer HH pads and the lever is a tad mushy for me.
Braking doesn't start till a bit later in the pull, but when it starts to clamp, I can modulate it very well.
I think this has to do with the larger piston size of the f4i calipers, and i'm sure a larger M/C like an SP1 RC51 or a 929rr one will work well with the larger piston setups.

Its really is just a matter of what you like. I wanted a larger MC and larger calipers with more pad suface....but I wanted very little lever travel. The stock setup on my 03 Hawk had more lever travel than I liked.....after having a Suzuki TL 1000 S with great brakes. I would have had even less lever travel with a 19mm MC than a 17mm master. I wanted the whole setup to look as stock as possible too!
I worked on my Brother-in-laws Hawk and all we did on his was just the capilers off of a 929 with good pads. It was a vast improvment but not near as good as my 954MC and F4i calipers with EBC HH pads....when I added the lines it was even better!
