cybmx Posted July 3, 2015 Share Posted July 3, 2015 I was thinking about something like this, does it improve the braking significantly? Link to comment Share on other sites More sharing options...
scordiaboy515 Posted July 3, 2015 Author Share Posted July 3, 2015 I was thinking about something like this, does it improve the braking significantly? most definitely, most true sport bikes use a radial style master cyl. with a bore size between 17.5mm - 19mm or so....give or take depending on what brand it is.

scordiaboy515 Posted July 3, 2015 Author Share Posted July 3, 2015 What is the different between 17-19?It's the diameter of the piston inside the master...the bigger the piston the more powerful but less feel....and vice versa 1 Link to comment Share on other sites More sharing options...

mericc Posted July 23, 2015 Share Posted July 23, 2015 I thought the brakes were based off the r1? 2015 Pearl White FZ-07 "such a torky lil guy" Link to comment Share on other sites More sharing options...
scordiaboy515 Posted July 23, 2015 Author Share Posted July 23, 2015 I thought the brakes were based off the r1? Nope, it's not a radial master like the R6/R1....just a generic off the shelf item Link to comment Share on other sites More sharing options...
RobMoore Posted July 23, 2015 Share Posted July 23, 2015 A you've lost your mirror mount. What are your plans now? Bar ends? Also, are you going to swap out the clutch perch for one without a mirror mount? Link to comment Share on other sites More sharing options...
dizzid1320 Posted July 23, 2015 Share Posted July 23, 2015 I know yours is a track bike, but does the GSX-R assembly have a brake light switch? Or would you need an in-line pressure switch? Link to comment Share on other sites More sharing options...
YZEtc Posted July 23, 2015 Share Posted July 23, 2015 I did this to my 2007 SV650K7 back then. I did it mainly (or, the most apparent advantage that came to my attention after doing it) because of the better shape and feel of the front brake lever.The lever is flatter and longer for more leverage, and the feel when using the brake was very good, indeed.If it actually makes the brake stronger, that's an added bonus. At least the stock front brakes of the FZ-07, with a change to EBC HH pads, in my opinion, are excellent to begin with. The SV? Not so excellent, stock.

scordiaboy515 Posted January 28, 2016 Author Share Posted January 28, 2016 I know yours is a track bike, but does the GSX-R assembly have a brake light switch? Or would you need an in-line pressure switch? Brake light switch is intact and the FZ07 connectors hook right up to it....no worries Link to comment Share on other sites More sharing options...

ravenlord Posted January 28, 2016 Share Posted January 28, 2016 I need to get around to installing the R6 brake master I have sitting around. I also have the brake discs and calipers, but I am not entirely sure if they will fit or be worth it. Seems that the rotors are only marginaly smaller on the FZ, and the R6 calipers from 2000 look the same as the FZ ones, but the R6 are blue instead of silver. Anyone want to measure the piston size of the FZ, mine is in storage. Link to comment Share on other sites More sharing options...

Anyone want to measure the piston size of the FZ, mine is in storage. Depending on the year R6, the calipers might be the mono block style which means they will not swap. The R6 radial master is made by Brembo, nice piece...much improvement over stock FZ. Weather street or track riding, the little FZ tops out around 125 mph....so the oem rotors and calipers work just fine. VIR N is very fast and has some very hard braking zones, never had any brake fade issues. Link to comment Share on other sites More sharing options...
pattonme Posted January 29, 2016 Share Posted January 29, 2016 @ravenlord, you found R6 rotors that fit the screwball FZ07 5-hole pattern? Link to comment Share on other sites More sharing options...
ravenlord Posted January 29, 2016 Share Posted January 29, 2016 Probably not. I have that parts R6 sitting around, and hadn't gotten past the whole I want to put the R6 stuff on the FZ. So odds are they do not fit. I will let you know about the calipers though. Link to comment Share on other sites More sharing options...
armourbl Posted January 31, 2016 Share Posted January 31, 2016 I'm guessing that most of the improvement you feel is from the braided brake lines. I'm sure this master cylinder is pushing a higher rate as well, and as long as that isn't too much, then you are fine. Get the rate wrong and you can end up with some really touching brakes that are hard to moderate. ben Link to comment Share on other sites More sharing options...

YZEtc Posted May 21, 2016 Share Posted May 21, 2016 Today, I installed this type of master cylinder on my FZ-07, too. It is a brand-new item from a 2011 Suzuki GSX-R600L1, is made for Suzuki by Nissin, and looks very much like the unit shown in scordiaboy515's first post in this thread. As I mentioned earlier in this thread, I've done this modification before on my SV-650K7, so I knew what to expect and I knew exactly why I wanted to do it: 1) To have better braking performance due to the much longer front brake lever with more leverage on the master cylinder piston. 2) The shape of the brake lever feels much better while on the brakes. Installation was so easy, you'd think this master cylinder came designed for this bike. Even the Suzuki front brake switch plugged into the FZ-07 wiring perfectly. The only down side is that I lost the right-hand side mirror mount. Out on the road, the brake works very well, is easy to control, and feels very good to my fingers. Very much worth it to me. 1 Link to comment Share on other sites More sharing options...
