Does the ABS unit on a 2011 ADV process the speedo signal into a different signal type?

    Whether that be a CAN bus data communication or other, or does it just act as a splice point for the signal and then send that same signal up to the Speedometer (what do they call the instrument cluster on this thing?) on a different wire? The reason I ask, is maybe it would be possible to jump a couple wires across the connector rather than having to retain, seal, and mount the circuit board of the ABS somewhere, when removing the ABS!

    TIA!

    Edit: There are lots of heavy relays, and magnets in that board. If I have to retain it I may see if I can do circuit board micro-surgery! LOL...weight and space, two things that are awfully valuable!

    Could you replace the instrument panel with one from an earlier bike?

    I wouldn't know, but that sounds expensive!

    I’m not sure why anyone would want to remove ABS - especially if running knobbies. It’s saved my @$$ more times than I can count in the last 5 years.
    I can grab/stomp a handful of stoppage in an emergency and never lock it up. Even better, if I don’t see a slick patch while on he brakes, no problem.
    It sucks on the dirt, but that’s what a switch is for AND the new bikes even allow you disable only the rear - BONUS.

    Slow pressure modulation (including releasing the brakes when they do lock) due to increased friction in the extra lines, ABS unit, and flex expansion on the extra hoses. GOOD brakes feel so much different than these. Not everyone will notice because they simply aren't that attuned to their machine, but if you rode your same bike with no ABS and perfectly matched brake components you would be mind blown as to how infrequently you need ABS once you can modulate pressure so precisely and quickly. But, you have to be on your game all the time (I pretty much ride like I am racing all the time, I don't "cruise"), which is tiring. For me I don't turn off, so that is not much of an issue to me.

    The 2010-2012 990 adventure R does not have abs (neither does the 2013 Baja I believe) and the R uses the same speedo and same wiring harness as the non-R bikes. I believe you can cross reference parts from your bike to the R to determine which speed sensor to replace without having to resort to retaining any portion of your abs controller. The R does not have the abs rings so I suspect Ktm used the non-abs speed sensor.

    @chevtech
    If my brakes felt sloppy, I’d get rid of the ABS too. My 07 might have the low-tech ABS cause I really can’t tell that they are there until they actuate and that doesn’t happen very often. Good luck with your removal.

    Sounds like it is time to look at some wiring schematics! Thx for the tip!

    Just this past weekend I tired connecting the front ABS sensor to the speedo pickup on my '07. It doesn't work. The ABS harness catches the speedo sensor plug with three wires - the ABS sensor is only two. Not sure what the ABS harness does with the sensor info but it's not plug and play like I imagined.

    If I'm understanding what you're wanting to do correctly, why not just get rid of the ABS and buy a non-ABS speedo sensor?

    Still trying to wrap my head around the different options and whether or not all harnesses, ecm, and speedo are the same with different wires used or if they have unique properties/part #s from bike to bike. To be honest I am a little confused about the different setups at the moment. Probably need to look at the two different wiring diagrams, and pics of non-ABS speedo pick-up. Cornfuzered!

    It has been discussed before.
    Up to 2008 models the speedometer is the same for all models, and the ABS module outputs a speed signal equivalent of the S models speed sensor.
    From 2009 on, the instrument cluster has different spare part numbers for ABS and non ABS bikes so you can't hook up a R model speed sensor to a ABS model cluster.

    OOHHHhhhhh. Didn't realize this. Sorry for the misleading conclusion.

    Exactly what I was looking for!

    So if I am understanding this correctly (that's a big if at this point) could you retrofit a "S" style speedo sensor and splice it into the harness going to the speedometer? I am unfamiliar with what a "S" speedo pickup is. Is that the one that goes off the bolts? Probably has a different mounting on the fork right?!?

    Correct.
    It senses the brake rotor bolts and it goes in a threaded hole in the caliper bracket.

    Just to be clear, the sensor thing works only whit the old style instrument.
