    I just look in my owner's manual and it's indicate how to see the wheel size on the speedometer, but I didn't found something about changing the wheels size. I have a set of 19/17 and the stock wheels 21/18 and really wish I can change it. I saw that it is possible on a 950 and on the regular 990.

    I saw some instruction on threads saying:

    Turn key on
    Press Mode until the F display comes on Press and hold both the Mode and
    Set buttons for ~ 10 seconds.
    The current wheel size will appear on the display Press Mode and it will
    toggle between 21, 19 Select 19 Press the set button.

    But on the R, the Mode button switch between ODO, Trip1, Trip2, Temp... can't display the F Mode....:dunno

    Any idea?

    You are probably the only one here WITH an R WITH 19/17 wheels.

    I thought about this also. Having a set of motard wheels would make this the ultimate dual sport. Im not sure if its possible or practical. Thoughts?

    I installed a set of Dunlop D607 on the 17/19 set and will install a D606/D908 combo on the 18/21 set.

    The 17/19 set are amazing on the street and the twisties. It's almost like a sport bike. And the 18/21 set will be perfect for the off road.

    I ride almost 2 hours a day in the city to get and get back from work. It's a lot more interesting to do it with the D607 than a D908. Also the off road tire wear too fast in the city. So I put them only when I know I will ride off road.

    But with the 17/19m there around 10 kmh more from around 90 and 120 kmh and something like 5 or 6 kmh more around 50 and 70. The speedometer is alway indicate more kmh than I really go and in the end, this put more km on the odometer than what I really do.

    I really need to find how to change the wheel size on this model!:confused

    On the Caponord thread, we start to discuss about the wheel size setting for the 990R.

    http://www.advrider.com/forums/showthread.php?p=15234851#post15234851

    Since I don't want to polute the Caponord thread, I put a link on this thread to continue the discussion about how to adjust the wheel size on the 990R.

    I remove the dash of my 990R to look at the connector and the different wire color.

    In the Caponord thread, Factory post this info:
    Then Guv posted this info:

    Then I found that in the 690 threadfest:
    http://www.advrider.com/forums/showthread.php?p=9716738


    All this info make sense but I stil have a problem. I remove the dash of my 990R to see the connector. It's a 32 pins conector and there's no pink or brown/grey wire.

    How I can locate the pin 18 from the connector? I don't have the electric diagram and I don't want to mess something in my cluster.

    Any idea?

    Here's picture of the 990R dash and pictures of the two sides of the 32 pin connector.

    I finally found the wire to disconnect!!! On the 990R, it's the brown/black wire. :D

    I tried to disconnect what the could be 18 pin wire with no luck. Since there's no pink and no brown/grey wire, I tried the purple, it doesn't work. Finally, it was the brown/black one.

    So to adjust the wheel size on a 2010 990R Adventure,

    1- press MODE to go to TRIP 1
    2- Hold the MODE key for around 10 sec
    3- It will show actual wheel size. Use the MODE key to increase the wheel size and the SET key to decrease it
    4- Hold the MODE and SET key to exit

    The default size on the 990R is 22.05 for the 21" wheel. I did some research on ADV and it look like the size for a 19" is 20.00. I can't ride because of the snow here so I can't confirm that this is the good size.

    Can someone can confirm that 20.00 is the right size for 19" wheel?

    Just went thru my 07 dash...(i have 17"s as well as the 21/18) and change quite often.

    The old speedos have the Inch and the other circumference in mm's

    21" - 2205 mm
    19" - 2040 mm
    17" - 1882 mm

    I just confirmed with a tape that the rolling circumference of my 21" front is within half a cm of being 2.205 m

    Thanks so much for this info

    I just had a set of SM wheels made for my 2010 990A I went for 17" x 17" instead of the 19" x 17".

    I also have the issue of the ABS light coming on after riding approx 1klm as the wheel speed on the front is now not in sync being 4" smaller than standard :cry

    It'd be nice if by changing the wheel size in the ODO, it might tell the ECU that the difference in wheel speed is ok - does that make sense??

    Anyway, even if it doesn't sort the ABS issue, it'll be nice to have the speed display correctly :wink:

    Thanks again for doing the research :clap

    For those who want to do this change with a 2010 990 Adventure standard ABS model...I can confirm that the instructions for the 'R' model as listed earlier are the same for the standard ABS model.

    I just removed that Brown/Black wire and now I can change the 'size value' of the front wheel :clap

    Brown/black wire works for a 2011 990 Adventure w/ABS - but it has to be the brown/black wire at the instrument panel (there is another brown/black wire with much easier access - makes it handy when you need to repair it - just saying)

    Dear all,

    I recently super moto'd my 690 Enduro R (2011 model) and soon found out that the speedo needed calibrating so I tralled the internet and found so many forums saying to cut either a grey/brown wire or a pink wire.
    Well I took my bike to my dealer as they offered to do it for free after speaking to KTM Austria who advised them the same thing that has been seen on these forums, well I am sorry toi say that it failed to recalibrate, but I have done it today myself and I am here to tell you there is no need to cut any wires and it only took me 5 minutes to sort it..
    Take the light mask off.
    Coming out of the instrument panel are a load of wires going to various blocks.
    The block you want has 8 wires going into it and one of these is pink. (colour may change but deffo an 8 pin block on a 2011 690 Enduro R
    Disconnect the block.
    Turn the ignition on
    ensure display shows trip 1
    Hold mode down for 10 seconds
    the word length will show on the clock and a 4 digit number something like 2205 this is the circumference of the 21" wheel with tyre.
    using the trip reset switch will decrease this number 1 digit at a time
    You need it to read 1870
    then press mode and reset buttons together
    turn ignition off, plug your connector back in, refit light mask and job done with no cutting.

    It's better to burn out than to fade away!

    On my 07 690 SM I removed the brown and black wire and my speedo unit went dead! So I put the wire back on an still no lights!
    Tested it carfully the unit and checked the fuse and still no lights. The unit seems to be dead. There was no short or any think eventfull during my attempt to adjust the speedo. Maybe there is and anti tamper system on this bike?
    Does anyone have any ideas?
    Be carfull

    For the older ones, 03-08, there is no wire. It's a trick with the buttons. You only have three choices, 21, 19, 17. Hold down the Mode button for a long time while in the main Odo? It's in the workshop man.
