dj790duke. Manual says 9300 miles or every year. I won't put that many miles on it in a year so it's every Spring for me. Agreed!! I used to change mine about every 3k mi or so, though like JD said, when I start to feel a lack of smoothness too it's time. I completely didn't agree with the manual as I feel like it is toooooooo long in between

KTM 790-890 Duke Issues And Problems. Have an issue with your 2018+ KTM 790 Duke? Share and discuss all related problems.

but if you fear for reliability (as the 2017 is the first rev of the new gen) go for the 2018 or 2019 - as they mostly have the problems prev. ones might have had sortet out (like on the 790: headgasket, routing of the tank overflowt tube)

He said the 1290s had tons of electric and no start issues ad the 790 adv had warped rotors all the time and the 2 Vilipen 701 they had have clutch slave failures --I said haha I know, my son rented that 701 to try one day and the slave cal went and pissed fluid out and no clutch. Anyway, I dont think KTM is paying enough attention to detail. alelo • '17 390 -> 2019 duke 790 -> 2021 duke 890r • Additional comment actions i think its funny, because my dealer in vienna has like 4 390, 10 890/r, some 1290 adventure/dukes, and lots of 690 enduro/SM and the offriad/Racing bikes - they also got a RC8R now :O
KTM 790 DukeWow! Been drooling over the new KTM 790 Duke. KTM continues to amaze with new offerings and the latest Duke is indeed amazing. 800cc verticle twin but designed to sound and deliver it's power like a V-twin due to it's 285 degree crankshaft. This puts the crankshaft journals at 75 degrees apart, compared to the standard 180 degree
