Hello Dr Ravinder Chopra, You are from Bahadurgarh ? as per your profile, So if you were present at the launch of new models of KTM bikes at bahadurgarh you must have seen me as I am the one who got the only Duke 390 available for Launch, And to clarify more the person who faced the problem with ECU is also me . Moreover the person who told about the part being imported from Canada in whatts app group is also me..

So First let me update you all about the ECU error, That was day before yesterday when I faced this error for the first time, and thankfully the last time. Yesterday entire day I was not able to ride my bike due to some work. However today I did another 45 kms ride. Although as I am going far from town on a highway I was little worried that in case I get the ECU error again in the middle of nowhere, I might stuck. But all went well and no issue. Drove slow , drove Fast, Drove continuously for 20 - 25 minutes, but no issues, I hope it was a temporary issue. However will get it thoroughly checked within 2 or days at first service, Hopefully at Bahadurgarh itself or may be at Rohtak. I hope the issue triggered must have been saved in computer logs and show some valid reasons when connected with diagnostic tool. And moreover if you reset ECU by turning off the ignition key completely, It restarts normally, so as of now nothing serious which can make you think of cancelling the booking or even giving a second thought. Go for it, its pure fun and VFM at this price. I will update you with the outcome of diagnostics as they will see error codes and reset all alarms after the service.

I echo Chiragsthakur's thoughts. I hear there are two throttle sensors, which is good - primary and backup.
But what happens if both stop working? How would I know if either one is/isn't working?

AFAIK, in other sport bikes where the Ride-by-wire throttle is used, in case of failure of the said system, the bike will run at a constant 6000RPM which should be able to go to speeds around 60kmph. That way you can reach the service center to get it fixed. I am not sure if that is the case with the new D390 since I was not able to find the user manual anywhere.

1. The bike will not run at a 'constant' 6k rpm, you could say that it will not exceed a certain rpm/speed.

How does the RPM change if the throttle doesn't work?

Thanks Chirag, Lets hope you get a positive reply soon. If you get anything, do let me know as well.

it looks like almost every new D390 owner has started facing this issue.

How many of them? I am quiet sure not many have got deliveries yet. But plz provide source if you can. And don't worry, if you are skeptical just hold on to your horses, ask the dealer to allot you a bike next month. Emi will start but anyways its gonna start on one day or the other.

Bad news. I did some inquiries and it looks like almost every new D390 owner has started facing this issue. I have booked my bike and it might arrive soon. I'm really confused what to do.. moreover, my loan will also be dispersed in a few days. How can KTM screw up this bad? Didn't anyone in their testing team face this issue during their runs? It's ridiculous that such a show stopper bug can slip through. Unbelievable.
