    13+ cbr600rr fly by wire front brakes

    Wondering about the fly by wire front brakes on the 13+ Honda 600rr. Not too sure about fly by wire brakes but the road tests all generally rate them as very good. Anyone have race experience with these? Did you swap out the front brakes for something else?

    edit - are my fears of fly by wire brakes unfounded or..?

    What do you mean "FBW brakes"? Do you mean ABS?

    I think OP is referring to Honda's Combined ABS system. It's not an unreasonable question, there could be an aspect of the system that makes it suboptimal for track use. Not that I myself have any knowledge on that one way or the other... however, I believe the system works via a normal ABS module, there is no braking by wire

    It is not "fly by wire". Hydraulic pressure applied by the master cylinder goes to the calipers. It passes through the ABS module that can nudge the controls if the rider does something out of bounds. Few roadracers keep ABS, tightly or wrongly.

    Below is an article quote for the 2013+ cbr600rr; with riders including Ron Haslam; sounds like fly by wire brakes. Don't know if I want a computer controlling the amount of hydraulic pressure going to the brakes-and they're saying this is exactly what is happening.
    News to me and not sure what to make of it.

    In fact, the brakes are astounding. Brake as hard as you dare in incredibly difficult conditions from high speed (around 120mph today) and the bike stops without you even realising that ABS is fitted. The system combines front and rear brakes together and stops the bike diving so much under braking. It's great on the track and on the road should be a revelation.

    The new system uses brake-by-wire. That means when you squeeze the lever at anything above 6mph, it sends hydraulic fluid to a braking power unit. This then sends an electronic signal and applies the amount of brakes required depending on the lever pressure.

    When you pull the lever, youíre actually getting the feeling of a conventional brake but itís through rubber springs rather than the amount of hydraulic fluid youíre sending to the calipers, and the computer is doing all the work.

    It sounds terrifying to a luddite whoís first bikes had a cable and a drum, but in reality youíd never know itís fitted, it really is that good, and unlike conventional ABS systems, Hondaís CBR600RR system doesnít give any pulsing at the lever when the ABS is kicking-in.

    That reads like somebody goofed on the media tech briefing. The hydraulic circuit has go to all the way from the master cylinder to the caliper, that is a critical safety feature of hydraulic brakes. I think brake by wire in passenger vehicles currently only exists in EVs or hybrids that manipulate braking for energy recovery.

    I found part of the slide deck that actually says "Brake-By-Wire" but the diagram clearly illustrates that it is not: https://world.honda.com/motorcycle-p...ail/index.html

    thx for the link. Im not certain that diagram provides enough detail to state unequivocally that hydraulic pressure from the master has a direct route to the calipers. Im wondering if this power unit is providing hydraulic pressure to the calipers, via electronics, even when braking normal w/o any need for the abs to activate. Even honda's blurp suggests this..I think? Going to look at this some more on the internet and see what I can find.
    .. Im not convinced either way.. yet

    The power unit you're mentioning is the ABS control unit. There is no production motorcycle made with electronically controlled pistons from a module based on pressure inputs from the lever/master cylinder. It's C-braking or combined braking, which has been around for ages.

    My 98 blackbird had combined braking...wasn't a fan of that.

    I personally think the way Honda used to put linked brakes on their bikes was goofy, but this is much more intelligent than that

    I think the reason linked brakes is a thing is because it saves the *** of inexperienced or bad-habit riders who only ever use the rear brake and never/rarely touch the front lever. Next time you're out with a mixed group of other riders, observe..and you may be surprised at how many people only use their rear brake.

    When the front brake provides 80% of your braking power, this is a potential big problem in an emergency situation for those who are scared of the lever vs the pedal.

    Linking fixes that.

    OK ... but the implementation specifically where it doubles the amount of hydraulic lines and you have multi chambered calipers and it alters the normal braking behavior of the bike. Stuff like this is the whole reason why people are still apprehensive of motorcycle ABS today

    Advanced or particularly knowledgable riders, sure.

    Squids, Hortons Choice, and your average 1000-2000KM/season rider (IE, the decidedly casual riders), these are the sorts who benefit from this sort of technology. I have zero doubt that linked brakes and ABS has saved many a rider from wrecks.

    When I posted my article link I had a feeling something wasn't right with the content. I am apprehensive of electronics and brakes together.
    I am now convinced that the master still controls things (whew lol)
    thx folks. Technology is moving so quick ..

    Oh btw ... in the course of fact checking this one, I learned that the ABS supposedly adds 22 pounds and people who tested the ABS on track said it didn't really affect braking performance but they didn't like the way it felt... so maybe non-ABS would still be the way to go for racing. I think ABS was a choice here for these bikes?
