Does either the 500 EXC-f 6Days or the 500 EXC-F standard model come from the factory with the quick shifter and/or the handle bar map switch installed?
Have your dealer follow the procedure of my last post with their xc2 software. I did it to my road legal 350, and I was able to replicate it on the road legal ES500 (same ecu as excf 500). All ecus can be reflashed with the original firmware. This is not the same as we used to do and flash euro firmwares. The switch has to be present with lights flashing during the reflash.I also realize this is an old post but I'll add a little info.
I recently purchased a 2025 KTM 500 EXC-F and bought a Combination Switch with TC, QS and two map settings. It was simple to plug in behind the headlight. But all lights on the switch illuminated and the switch did not function. I took it to the dealer who had it for a week. They finally called and said they couldn't get it to work. They talked to their KTM Rep who said the ECU could not be re-flashed because the EXC model was street legal and this would interfere with emissions.
So at this point I guess the only remedy is to send it out for a $500 reflash at a non KTM business.
Is there any other solution???
