BMW G650 X Bikes – Rear Wheel Size Display Swap

For the BMW G650 X Bikes(applies to all the BMW G650 Xcountry – XChallenge – XMoto) – There is always a possibility for you to swap the rear wheel diameter size between 17″ or 18″ rear wheel selection.

The computer does the calculations itself with the rotations or the speedo adjustments based on the size that is already fed into the computer. It is always a good idea to be able to have the right readings while I personally do not have an accurate measurements of how much difference do they read between each selection.


The process to swap the sizes is a little more than tricky as you need to hold the button and to adjust the battery connection at same time.
Tip: Easier if someone else can help you as well to hold the battery.

Instructions:
This is how to change wheel size:

  1. Remove ignition key from lock and disconnect battery.
  2. Press the Set-button and connect the battery.
  3. Don’t let go of the Set-button until i’ll tell you so!
  4. The software version is shown on the display.
  5. Don’t let go of the Set-button until i’ll tell you so!
  6. The display counts down from 15 to 0.
  7. When the countdown completes the parameters of the wheels are displayed, one after another.
  8. Now you can let go of the Set-button.
  9. When the wheel-size you want (diameter where speed is usually and circumference below where odometer is normally found) appear on the display, press the Mode-button.
  10. That’ll save the new wheel size in memory.
  11. Disconnect and then reconnect battery (don’t know if it’s necessary but that’s how I do it and it works).

Do note, that the combinations normally runs with 21" front and 18" rear on XChallenge Wheels.
For the XCountry, it runs as 19" Front and 17" rear on XCountry.

Swapping 18″to17″ OR 17″to 18″


I will add-in the pictures once I do the swap between the two different sets of wheels and makes life easier to do the things at the same time in above sequence.

Hope this will help you get to choose your right wheel display settings too.
