Changing Speedo Calibration on Yamaha WR Computers

2009-2011 WR250F / 450F
(Does not work on WR250R / X models)

  1. Push the SLCT1 and the RST buttons simultaneously and hold for 2 seconds to enter into the tire diameter correction mode.
  2. The display should now show 100:0C (stock)
  3. Press the SLCT2 button until it reads your newly desired correction factor XX:XC.
  4. Push the SLCT1 and RST buttons simultaneously for 2 seconds to exit the tire diameter correction mode.

Calculate new tire diameter and determine what percentage of the stock size it is:

  • Tire Diameter = (Section Width X Aspect Ratio X 2 / 25.4)+ Rim Diameter
  • 17” Supermoto: 120/70HR17
  • 120mm x .7 x 2 = 168mm / 25.4 = 6.61″ + 17″= 23.61” x 25.4 = 599.80mm
  • 21” Stock Dirt: 80/100-21
  • 80mm x 1 x 2 = 160mm / 25.4 = 6.29” + 21” = 27.29” x 25.4 = 693.40mm

2012-2015 WR250F / WR450F
(Does not work on WR250R / X models)

  1. Remove headlight
  2. Drop the boot of the back of the speedo harness, cut and seal the grey loop wire.
  3. Put it all back together and install on the bike
  4. turn the bike on,
  5. hold rst + slt1 buttons (100c will appear),
  6. press slt1/slt2 until you get the correct number for your tire (should be 85-86 depending on your tire) use tire information to work out your diameter.
  7. hold rst+slt1 again to continue normal function.

100 is 21” size and 86 is 17” size
