I added a potentiometer as a voltage reducer to o2 sensor; Works perfectly.I got a 2019 390 in July.
Great bike. It rips below 120km
The lurching below 4000 was disturbing though. I got a Powertronic which made bike into a race track worthy bike, however lurching was still there. I added a bung and an AME wide band gauge.
I then added 5-20% fuel at 2500 to 4000 rpm, up to 20% load.
As long as I modulate throttle every 5 seconds or so, lurching is gone !
Hi JPM,Hi All!
New here and hoping to get my Duke soon.
If somebody could point me in the direction of where to discuss earlier model 390 Dukes(2014, 2015) and how they do at high mileage 70 000km+ and related items
Thank you!
Thank you KTMasean, appreciate the input. Mind if I ask whats the mileage on yours?Hi jpm III,
Welcome to the forum.
All generations Duke/RC 390 are discussed here, I ride a 2015 Duke 390 (because I also ride what I like) and if regular oil changes (+filter) have been observed I see no reason to rebuild the engine.
If you buy this second hand at 70,000 km I would renew all fluids (including brakes), and do the 15 minute ECU reset procedure (search the forum).
Check fork seals and renew the spark plug.
Enjoy the ride.
Thank you Duke of Wentworth!Hi JPM,
Well thanks and good for you!, although the Duke 390 seem like a sturdy bike (and I would be surprised to see some with 50K +) you have to keep in mind that this is a monocylinder and they need preventive maintenance, after 40 K Klicks you might have to tear the engine apart and re-do-it!, very simple mechanic and easy to work on!
I myself went with the 2019 because I have to like what I ride, but then I wasn't disapointed with the overall performance, that thing is a little Monster! and it drive superb! from the seating position to the ergonoomic I can't hardly find a defect, except the rear shock but then....I replaced it with an Ohlin! lol good luck with you choice!
Thank you KTMasean, appreciate the input. Mind if I ask whats the mileage on yours?
Thanks again

Hello from Wenatchee Washington USA! Old fart recently getting back into the Moto life. Just added to the stable with a 2018 Duke 390, cream puff perfect with 1820miles on the clock, basically a new bike! Stoked with it thus far except the left fork leg started leaking once I got it home, strange but oh well, just got a 43mm Motion Pro seal driver today so it'll be back together by sundown, as I look outside at snow on the groundWelcome to KTMDukeForum.com - we are the internet's friendliest KTM Duke site dedicated to the 2013+ KTM Duke!
