    Got my switch hooked up today. Works great. Thanks Stephen.
    I highly recommend the switch, for those rare times you are on dirt, and have forgotten to push the button.

    I once used the sliding stop technique of last resort when it was better to slide under the front end of a monster pickup than become the hood ornament. In this case, there was no escape right or left, and "getting low" was the way out and it worked. Thankfully.

    I once overshot an increasing-radius turn getting on a highway, jumped the curb and ended up skidding across wet grass (upright) toward a small pond/swamp. I laid the bike down and managed to only partially submerge instead of careening headfirst into the bog.

    In both cases I managed to get my leg out from under the bike. In both cases, the course of action of last resort - laying down the bike - turned out to be the right one and I'm not sure what I would have done if I had ABS at the time.

    Maybe it's inexperience with ABS, or learning how to ride as a kid at flat track races, but I find it disconcerting to not have control over the method I would like to use to stop under certain conditions. On dry pavement, at speed, ABS is definitely my friend. I'm still not too keen on it under other conditions. But maybe I just need to get used to it as a new tool in the toolbox.

    I appreciate your explanation here. It really helps me to understand what's going on in a 2-wheel ABS system.:ear

    Cheers,

    Got my ABS kill switch hooked up last week and finally had time to give it a proper test on backroads today.
    Works great! One less thing to worry about when spending a day on gravel / dirt!:clap
    Thank you Stephen!

    I pulled the rear wheel sensor wire into contact with the tire and tore it up (not intentionally as that sentence sounded). The wires being broken there is what this switch you guys are talking about would do right? So I guess I can comment on what experience I had with that. I didn't take note of the auto-off on the turn signals, but I did notice other accessory functions not working. The heated trips wouldn't fire up. I reconnected the rear wheel sensor with some electrical tape and they started working again (along with the ABS). I seem to recall one other "extra" that was also on that same system, like the computer or mileage sensor or something.

    Anyway, I just thought I'd say, TEST EVERYTHING if you are going to wire in a switch to break the ABS circuit. I figured it was all the stuff off the same bus that wouldn't work if one was out.

    From an earlier post, pulling the plug under the seat or tapping into that circuit with a switch deactivates the ABS.
    This may be a silly question but ...
    could you use one of those autoswitch AS7 units running off the standard ABS override switch with a relay to do this?
    That would be the ultimate - using a double push of the ABS switch to cut the system while moving and another double push to reactivate it as you get back onto the bitumen. Seems like this idea only works for the off cycle and not for back on - have to shut the bike down for that one ?

    Being able to switch while moving would certainly save the having to stop to reset on or off.
    Only thing worse is my mate on his 1200GS stopping everytime we hit dirt to change his ESC setting :eek1.

    So for those of you that have installed the switch, does the ABS light on the dash stay lit or does it blink? I've looked through all the threads (thanks for the reply Stephen), but can't seem to find an answer. Thanks in advance.

    Nvrmd. Thinking of something else. They are ESD sensitive, not mag field sensitive.

    As stated, it stays lit, solid, no blinking.

    Taking an old thread up... I have -13 F800GSA and I'd like sometimes to be able to fully disconnect the rear ABS. I do have the option for ENDURO mode that works well yes, but still does not fully disengage the ABS from the rear. If I use the handlebar switch, it disengages the whole ABS and that I don't want, as I want to have the ABS on in the front.

    I read the whole thread and came to a conclusion that using this harness will also disable the ABS from the both ends? Is this the case?

    ...and there was also a report that disengaging the ABS this way will hassle with the OEM heat grips and probably with something else as well. If this is the case, this harness is a no-no for me.

    Sorry, but don't have any Tech. advice regarding your specific question but ...

    Happily share what I think about ABS & riding on loose ground.


    My belief is that ABS is a tar road thing completly, have suffered the consequenses by using ABS on gravel and it's plain scary, when the ABS feels that the tyre looses the grip during braking it just let the brake up ... imagine a really rocky sandy downhill, the speed builds up & eventually you want to slow down just to notice that you are without brake effect :eek1 the only thing to do then is to steer & aim and hope for the best.

    Initially when you are new on looser ground ABS can be a good thing as the pace overall is rather low & the possibility for to much brake in the wrong moment are high. But here it doesn't matter if it's both wheels.

    When the knowledge & pace builds up to the level were you think you can get rid of ABS rear you should have reached the skill level to handle a front without it also.

    I always use ABS on tar but never again in the looser stuff. The memory of 3 broken ribs & a severed crashed bike still hurts. Forgot to turn the ABS of, came into really loose stuff in 55mph, wanted to brake down abit ... zero brake effect, pressed the bike down to be able to take a corner and the front washed out & down I went :p3rry

    Just my 2 cents ...

    What would happened if I quickly shut off the engine?

    Might that be a way to save oneself from a disaster?

    Well ... remember that the most critical situation usually occurs in parts of a second. Part of that time you are surprised that you hasn't any brakes & try to brake over and over again, the rest goes for just steer & avoid the crash.

    If you are going downhill in a straight slow pace and notice that you have lost brake power due to the ABS way of working, then you have time to make your decision... engine braking would be my choice.

    I am familiar with the system and I am not aware of any method to disable the rear abs only.

    Been using this switch for a few years now and it works great. It's wonderful peace of mind knowing ABS is off for extended offroad jaunts. One issue I wonder if others are experiencing though.

    It appeared my fuel mileage was dropping from the mid-50s into the 40s MPG. Turns out it was my trip meter reading long making my mileage look worse. I compared readings with roadside mile posts and other bike's odos while on the same trip. After experimenting, it appears that if I disengage the ABS using this switch for a while, I get about 10% error on my trip meter (and odometer). If I turn the ABS back on, the mileage on the trip meter is back to normal.

    Any one else can confirm this?

    >>>You must STOP, press and hold the ABS button till the brake light glows red and then continue. There's no need to turn the engine off. When you want to re-activate it, you must stop, press the button again and go.<<<

    Yeah, so 5 years after original post I offer a correction. You CAN re-activate ABS while riding if your bike is still stock. If ABS is on, just pull and hold clutch fully in while at speed, turn ignition off, turn ignition back on, release clutch while in gear and the ABS is back on. I do this sometimes when I come off a dirt road back onto slab and want my abs back on. Yea, I am coasting at 45-60 MPH for about 2 seconds until the bike restarts....
