    Request for a little update (still haven't started to put the switch on my bike :cry): Do you know if it generates errors that the dealer can see if he hooks the bike up to the computer?

    By "red handlebar switch" do you mean the main switch on the right hand switch unit?
    So do you replace OEM wiring into this red handlebar switch?

    Sorry English is not my native language.

    No, he actually added a new pushswitch to the left hand side unit, pics are not showing anymore for some reason (on my pc :huh)...

    So in theory he fakes a shortcircuit in the sensor which disables the ABS on the fly.
    Should not hurt anything but I wonder if the CDI logs errors about this...

    Is it Triwi avoids cuting the OEM wires? Seems the same to me. Or is it yours doesn't produce error signals? Pls enlighten me. Cheers.

    P.S. Pictures are not attached any more because we need to host them on a pay host somehow. My "masterpiece" study on slave cylinder failure is crippled. Oh! what the hell?

    I don't have a solution yet... But I think I will try Triwi's this winter.

    But this is Triwi's:

Whenever the ignition is switched on the ABS automatically resets. No need for a rocker type switch which has to be manually switched which is needed if you loop just one side of the circuit to the bar switch.
    Have to say I did querie the sparky about apparently introducing a short circuit by doing it this way but he just smiled and said No. Before doing the 990 I alterred my 650 Dakar and have been running it for a month. Works perfectly. No ill effects whatsoever plus the bonus of automatic reset every startup.

    Maybe if he sees these questions, he will post the pics again :norton

    The only difference between Triwi's version and rgmax's version is the switch. Both require cutting into the rear ABS sensor wires. Triwi's version uses a temporary interrupt button which disables the ABS as long as the bike remains on. Same as the stock button, but no 3 second holding period, and also works while the bike is moving. If you turn the bike off and turn it back on the ABS will be active again. rgmax's version uses a permanent interrupt switch which disables the ABS as long as the switch is flipped. If you turn the bike off and turn it back on the ABS will still be deactivated unless you flip the switch back before you turn the bike back on.

    I prefer the permanent switch because I don't want to have to remember to turn the ABS off everytime I restart the bike offroad. ABS on dirt is SCARY. This comes with the downside of forgetting to enable the ABS on the road. Much less of an issue. I've ridden plenty of other bikes on the street without ABS.

    It really comes down to personal preference. Do which ever works best for you.

    What I did while riding off road for the weekend was just put a couple washers between the sensor and the housing onthe rear wheel. Moving the sensor away from the ring by just that small amount made the signal unreadable and the ABS was off.

    To under just remove the screw and put the washers on the other side outside of the sensor and your done.

    No cutting into the wiring harness and takes only couple secs to do.

    The really cheap penny trick.

    :deal

    Then it's off permanently, and so, can not be activated again easily/fast when riding home on the road... But I like the idea for a 2 week offroad trip though :clap

    Absolutely brilliant. Would I be correct in thinking that the front wheel is still ABS while the rear is not?

    Doesn't matter... I like it...

    Drive 2500kms to the south of Spain, enter Marocco, put the washers in, ride 10 days offroad without thinking of deactivating the ABS all the time, enter spain again, remove washers and ride 2500kms home... cheap and certainly no malfunction...

    Don't think so....
    But you can not do this with the front sensor as the cable is also used for the speedo, or am I mistaken?

    Once the system sees an ABS fault code the system as a whole is deactivated. They are a shared circut not independent of one another.

    All or nothing.

    There's an even cheaper fix.

    Just unplug the rear sensor wire located under the seat above the shock.....

    Do you have a picture of that?

    And in this cheap versions, do we get an ABS warning all the time?

    From what I have done on the bike the light will just remain lit that is all.

    Even with the 'trickier to do' switch fitted into the wiring for the rear sensor ............... the warning light stays on - but that's good because it reminds you the ABS is off.

    I did the switch in the rear sensor wire a while ago. it took about 1/2 an hour to do, the switch is pretty well concealed - but comes in very handy for a day off road.

    When the bike was last serviced the dealer told me I had a lot of error codes for the ABS rear sensor - but they couldn't find anything wrong ....... which means they didn't spot the extra wiring and switch ......... which probably means they didn't really look for any faults either!!
