Recalibrating the Speedo for 17" Wheels

(1/3) > >>

Hey all,

Considering an SM conversion.  I located this info on recalibrating the speedo.  I love that KTM makes this so easy; my WRR required a separate component to adjust the speedo.

Follow the pink wire from the speedometer under the headlight mask to the connector.

Disconnect connector.

Turn bike on and cycle to where the dash is displaying Mode 1.

Hold both buttons down for about 10 seconds.

The wheel size should now be flashing.

Change the wheel size to 1870 for the 17" wheels.

Press both buttons at the same time again.

Turn bike off.

Turn bike back on to verify that wheel size has been changed (so you don't have to undo the headlight mask and fiddle with the plug again)

Connect plug under headlight mask.

Go for a ride!

The process becomes very easy once you do it the first time. There is plenty of room under the headlight mask to undo the plug. I did not cut any wires and will not. It's just too easy to unplug it and plug it back it in.

Thanks to Buddoggin at Thumpertalk for this concise tutorial.

If anyone does this, I'd love to see some photos of the surgery.  Specifically, I'd like some photo's of this wire that needs unplugging.

**See below: another source claims it's better to simply cut the wire at pin 18, and never have to unplug anything to change between wheel sets.

Hey!!! That's me!!! lol. I did share that on Thumpertalk but I didn't write it. I think I found it on SMJ.

What yr is that for? I got an 08 enduro im trying to set the wheel siz for right now.  :-X

So im trying to recalibrate my 08E speedo and im having a bit of trouble. There's no pink wire, so I consulted the manual. It says to unplug the main harness the joins up to the computer and the pull pin 18A. Mmmmk, so there's a pic too, but its fairly dark and unreliable. So I then flip back to the wiring harness diagram, to try and locate that exact wire. I can find a bunch of different things that plug into that harness, but not the speedo sensor. Anyone know which color wire to unplug so I can reset this damn computer finally?  >:(

Rusty Shovel:
I wonder why the speedo requires ANY wire to be manually plugged/unplugged.  You'd think this would be a completely electronic issue.  Anyone try doing this without unplugging the wire?
