Speedo recalibration te449

Hi could anybody help me by letting me know if it's possible to recalibrate my speedo as it now reads incorrectly having changed from 21 inch to 16.5 inch supermoto wheels. The bike is a 2011 te449.
Thanks in advance

I don't believe it's possible. As i understand it the speedo gets identified as a TE or SM model at the build, and that "burns" the calibration in so it can't be changed. You can identify the speedo calibration when it starts up as it briefly shows a code, i think mine say something like S41E, I have the opposite problem where i have an SM speedo on my TE and it under reads. I think E41E is the startup code for Enduro TE calibration

I agree. And if you don't want to lose your turn indicator/fuel warning/hi beam/"fail" msg.... AND you're not up to re-wiring this stuff, put the trail tech right next to it; or even use a little speedo from a mtb/road bicycle (eg, cateye). both simple & cheap.

good luck.

thanks for the replies, you'd think there would be a way to do it considering the variations of the same model. My next option was to research a device made by Healtech called a speedo healer which can be calibrated to suit your wheel size. Maybe this might be the solution to my problems.

You can fit a unit called a Speedo Healer to the factory dash to modify the pulse signal and get the readings correct.
That way you can keep the factory dash for the reasons listed above.

I have the Speedo Healer on my 2011 Te449. I got the two wire with a/b switch because I switch form the 21 to 17 depending on what I want to do that day
