    That's really scary. I parked my 2008 Adventure for a few weeks. Everything worked fine, then got it out the garage yesterday for a ride and I noticed the ABS was going haywire. The ABS shut itself off a few seconds, then I noticed the speedo wasn't even close to being accurate. Next thing I know the speedo went to 0. Seeing as how I was passing cars I was pretty sure I was going faster than 0 MPH. After that I also noticed the odometer isn't working either.

    I don't have a clue what to do to fix this. Unfortunately the dealer I bought mine from went out of business and the nearest one to me now is 45 mins away. All the cables look good on the outside and all the fuses are fine. So yeah, I have no idea what to do now.

    Speedo reads 0 and miles don't turn.
    Everything else works.

    Changed sensor and cable, and still didn't work.
    Took speedo off my bike and put on buddies bike, and it worked.

    No, I've never taken front wheel off bike.

    Anybody got a fix?

    I think you've pretty much narrowed it down to the unit itself, if I'm reading you correctly. You might be able to get a speedo shop to fix it. Your other choice seems to be a new unit.

    Took speedo off my bike and put on buddies bike, and it worked.

    If your speedo worked on your buddy's bike, there can't be anything wrong with his sensor, cable, ECU or wiring.

    Is the position of the sensor damaged or something? You could check it with your friend's. Err! your friend has an S or a 950? Do you install the sensot properly or wrong side close to the rotor bolts. You do have the rotor bolts that trigger the sensor? The only thing it could be is the first sensor got damaged and the second wrongly installed?? can't think of smthg else. Keep us posted.
    Cheers.

    So Paulinator's 2008 S is still broke. Zero on the speedo, $330 spent at dealer troubleshooting, installing a new cable w/ sensor. Money wasted!

    My head unit does the same thing on his bike (reads zero)
    His head unit on my bike works.

    It ain't the dash unit (check)
    It ain't the sensor or cable (check)

    I mean these bikes have NO ABS, and there are only 3 other wires as posted above and they seem to have 12V power via us checking with a voltmeter.

    OK - fire up the suggestions..............

    I'm looking at a wiring diagram for a 950 so assuming its the same still for the 08 990 the blue/yellow wire from the head unit is the positive/power for the speed sensor. I'm no electrical wiz but my guess would be that the sensor is creating an electromagnetic field with the power from this wire. The sensor wiring does not show a ground so I'm guessing one of the other two wires is the return for this electromagnet. The third wire would then be the one that actually sends the pulses generated in the sensor to the head unit. In short, if you are getting 12V between either of the three wires and a ground to the bike then something is amiss.

    My first guess would be that there is a broken or shorted wire between the head unit connector and the speed sensor connector, its the only thing you haven't switched yet.

    Good explanation - I'll have to investigate this as we have eliminated all other options...

    hi. i'm riding a '04 950 adv...i came across a similar problem. it started with the numbers on the speedo jumping here and there, not giving the correct speed. it ended with it not showing anything but a big "0". what i did was i sprayed the sensor with some aerosol degreaser, and hosed it off. it worked fine after that. i've been doing it ever since then, whenever the problem arises. it seems like a simple enough solution...too simple in fact. but it worked for me. i hope this helps.

    I ended up taking mine to another dealer. Turns out one of the front wheel spacers was missing on my wheel. Which caused the wheel to shimmy back and forth. That eventually destroyed the sensor and even damaged the cable. So I had to replace both.

    The odd thing is I never felt the spacer missing while at speed so I never knew it was missing. I did notice a weird feeling at very low speeds, but it felt like a fork was sticking. I had never felt anything like that before so I couldn't even describe it to the mechanic. I never thought to take the wheel off and check for that myself because the front wheel had never been off on my bike. So it came from the factory missing a spacer. Lovely.

    hey all, while out riding the other day on my '11 Adv R, all street in pretty hot conditions, my speedo suddenly stopped working. I've never taken the wheel off, until today. I am getting ready for a trip and leaving on aug 5th so am getting new rubber. I have 8k km. And now this problem presents itself!

    I've checked the fuse (glovebox ones). All ok.

    I've checked the speedo connector and sprayed it with electrical spray for any oxidation. Nothing.

    I've checked the magnet at the other end of the speedo wire, cleaned it up. Nothing.

    I've taken the speedo wire completely off and inspected it, looks perfectly fine.

    While taking the off the speedo wire, I noticed a second wire, that is connected with a small white connector (not as big as the speedo connector) up behind the headlight along with all the other bike wires, and from here it runs ziptied, down along with the speedo wire down along the left brake line. While the speedo wire goes down and the magnet is screwed to fork, this second wire suddently stops just below the lower triple clamp It's literally a dead end wire. What is this for, is it for those with ABS? Also, the end of this wire looks like it could be a little damaged.

    Unfortunately I "may not post attachments" otherwise I would post some pics.

    Almost forgot, this morning when i first got on the bike the speedo worked, well sort of, I saw a 6km then back to zero. Done, nothing more.

    Along with the speedo the odometer does not work. Everything else, highbeam, horn, lights, blinkers all work.

    I am hoping to resolve this before I leave for my trip around Mt. Blanc/Val d'Isere!

    Anyone have any suggestions I am going crazy!!!

    Should I just go buy a new speedo wire and hope that is it? I also don't know how to test the one I do have...

    Cheers.

    I have a 990 Adv White ABS 2009.

    I have same problem related above.

    i start riding, velocimeter and odometer work's fine.
    After few miles, velocimeter goes to 0 (zero) and odometer doesn't count any more.
    I have changed 3 times the SPEEDOMETER (part number 60114169000 ), and the problem goes on.

    Now, i will exchange the "abs sensors".
    i will Install the back abs on front and vice-versa, to test.

    any ideas, about this problem?

    Had similar speedo showing zero except when turning on and off. Never found out what happened, but I suspect CDI problem.

    On my second speedometer!

    Purchased my 2008 SuperDuke in 2011 with a one year warranty. The speedo went out a few months ago. The odometer needle stuck at 4k and everything else on the LED screen had disappeared.

    Brought it is to Scuderia in SF and they replaced the speedo with a new unit. I put about 1500 miles on the bike since then and the speedo goes out again. Same exact symptoms.

    My warranty is expiring in a month but I already reported it to them and they couldnt not figure it out. I just dont understand what is up with the bike.

    Anyone else have these issues.

    Just a thought, check your voltage and make sure your voltage regulator is not on the way out. I would actually mount a meter and go for a ride.. Over voltage to the dash could be the problem.

    Agree, it won't hurt check that for peace of mind. My failing regulator made my Speedo and ABS act funny, burned the ABS sensor and a few bulbs.

    I was wondering whether one needs to take the front wheel off in order to replace the speedometer cable or is it just the left brake caliper? Advise about the correct procedure would be appreciated. :ear Thank you.

    Not familiar with 950/R/S bikes (non ABS models) but in a standard 990 with ABS you just remove the bolt that attachs the sensor and cut the zip ties to take the cable off. No need to remove anything, you'll figure it out as soon as you take a look down there.
    The cable, however, plugs into the ABS button so you have to remove the headlight.

    So i rode the entire summer without a speedo. I have a gps so i know the km i've done in that respect.

    Recently the speedo started working again, but on and off. From time to time when showing zero while I am riding, if I take a right hander, by leaning the bike, the speedo works. Then straight again it goes back to zero. If I lean left, it does not work. I've checked the front wheel, seems on right and the spokes are all tight.

    WTF is going on?

    gyroscopic speedo?

    I would check connectors and cables going to the speedo/clock.
