Drestrict does NOT work on TSX confirmed.
Feel you... I also noticed the same thing. Bought this new TsX to my son and derestricting following different YouTube videos made for TS doesn't work. There must also be new firmware in this bike and by that they have made some modifications for derestricting sequence.
It would be greatly appreciated if you could share the new way for derestricting here if you are able to sort it out how to do it. I will do the same if I am able to find a way. My dealer was also unwilling to share the information although he said that there definitely is a way.
