Cracking the KTM CDI code!
In 2018 I also worked on cracking the CDI coding and think I got quite close!
Here a 2015 KTM 125sx CDI number: 503 39 231 000
I will replace the numbers with letters: ABC DE FGH IJK
Where, I think (but can be wrong) that the letters represent as follows:
AB = bike model. 65cc=46, 85cc=47, 125/144/150/200cc=50, 250cc=54 etc
THE ABC = 503 FROM 1998 - 2015 WAS FOR THE 125/144/150/200 ENGINES FROM 1998-2015
C = version of bike (looks like these are not based on a year but the number goes up when a new version is released). 125/150sx: 2000-2015=3, 2016-2018=4, and a resently released upgrade of the CDI for 2019 models have '5' in the C spot.
DE = Manufacturers code. All KTM CDI's have 39 here. (039 in a standard barcode represents USA... but I would not assume they have worried abot aligning themself here in some way). This could also be the number that means KTM at the manufacturer. (Could also just mean "CDI")
F = Country of use for the CDI. 0 = General, 1 = Europe, 2 = US
GH = Not sure, but all CDI's have 31 here. Again, could be manufacturer or country the CDI comes from? Or perhaps just mean CDI.
IJK = This would be upgrade number and some other inside number like who did the upgrade etc.
NOTE: Where a CDI is suitable for more than one model of bike the three first numbers will be different to indicate this. I have not been worried about trying figure this out.
I might be totally wrong and you might have some factual info (as I have only based my conclusions on what I have been able to figure out). If so, please share!!
WHEN WRITING THIS THERE IS NO SXS VERSION OF THE CDI AVAILABLE FROM KTM FOR 2016 BIKES ONWARDS
SUPPLIERS CAN ONLY CHANGE THE MAPPING IN SOME OF THE XC MODELS, BUT EVEN THAT WILL STOP SHORTLY
EDIT: NOTE, the CDI in the picture below is a 2019 version one and not, as the text in the picture would have you believe (a 2016 version). The "5" in the "C" spot is the giveaway. Sorry re any confusion.
