Gen 1 master cylinder with 32mm piston calipers

[Gumpert]

Hello all


I recently bought a 2005 gen 1 and really want to upgrade the brakes.

I’ve been looking at the HEL V1 calipers which I believe have 32mm pistons.


The question I have is will the stock master cylinder pump enough fluid to the calipers for it to be a worth while upgrade?

I don’t want to use the radial master cylinder as I wouldn’t want it to make contact with the speedo cluster.


Does anyone have any advice on the subject?


Cheers

Welcome.....

There are post after post on this very subject.......and lots of opinions.......

In almost each and every thread, the mention of upgrading the master cylinder is the number one upgrade over anything else.

You can pick up Gen 2 Brembo calipers that are pretty decent, change out the lines to a good aftermarket steel set, put on a set of EBC HH Sintered Extreme Pro pads and find a Brembo master Cylinder from a mid 2000's R1 and you are GTG.......

Change out the rear pads and lines and you are GTG there too....

For a little over a grand, you can get brakes that will give you one finger stopping....

You will need a better mc to see any real benefit from those calipers, and you can add a radial mc that and clear the inner windshield.

We both forgot to add the "Frank" (BerlinGermany) part and ensure the calipers get a detailed cleaning

Flush brake system, deep clean calipers, replace pads, change lines to SS, revisit braking options. RCS19 MC will do wonders

This is true, I left my OEM calipers on but 'deep cleaned the calipers' and added stainless hoses and a 2009 GSXR1000 radial m/cylinder.... it transformed my brakes, the lever has instant pressure at the m/c, no more half way to the bars any more.
Very firm lever feel and great bite from new aftermarket rotors and new EBC HH sintered pads.
Total cost was $500.

Does that master cylinder make contact with the tacho ? That’s my worry with the rcs19

Im confused about the question. It fits as the stock one does. Only diference is that you will need to mount the fluid resovoir. There are many options and ways to do it. A bunch of us here ran or still run those on their Busa's. Hell Im about to put one on my Harley

I’ve been reading when the steering is at full lock to the left the Brembo RCS19 makes contact with the clocks so I’d rather avoid that MC. Do you have that problem with the r1 MC ?

I have an R1 Brembo MC with zero issues at all......as the reservoir is a separate item, it can be moved around to ensure it doesn't hit anything.....

This mod has been done to many Hayabusas over the years.....

This is why it is such a great platform, almost anything that can be done.....has been done.....

I’m running Renthal bars mounted on an aftermarket top yoke with low risers on my Gen 1 and there’s no clearance problems with that set up ….can’t say for sure if it clears on a standard handlebar arrangement.
Here’s what my set up looks like..

NO need to fit the BIG Brembo reservoir , i use on 3 MC / front brake /clutch and Rear MC ,the tiny reservoirs
I call them PAD Indicators

All parts fit on ABM Superbikekit and Spiegler 0229 Bar


first picture OLD Brembo RCS 19 Brake MC and RCS 19 !!! Clutch MC , also ABS Light plus on/off switch for track days.
