TL* THE CONTACT OWNS A 2017 KTM 390 DUKE. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE STALLED. THE CONTACT ALWAYS MENTIONED THAT THE OIL PRESSURE WARNING LIGHT WAS ILLUMINATED. THE CONTACT STATED THAT AFTER 10 MINUTES THE VEHICLE WAS ABLE TO RESTART. THE CONTACT ALSO MENTIONED THAT ON A DIFFERENT OCCASION, THE VEHICLE WAS UNABLE TO START. THE VEHICLE WAS TAKEN TO SCOTT POWERSPORTS, INC 1675 PA-309, COOPERSBURG, PA 18036 (610) 282-4800 WHERE THE FAILURE COULD NOT BE DETERMINED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT NO ASSISTANCE WAS GIVEN. THE FAILURE MILEAGE WAS APPROXIMATELY 7.
THE COOLANT IN THE RESERVOIR TANK BECOMES EMPTY WHEN DRIVING THE MOTORCYCLE FOR AROUND 100-130 MILES IN NORMAL CONDITIONS. THERE SEEMS TO BE AN ISSUE WITH THE VALVE SEPARATING THE ENGINE OIL AND THE COOLANT. DUE TO THIS ISSUE, THE COOLANT LEAKS INTO THE ENGINE AND CAUSES ISSUES LIKE HIGH ENGINE TEMPERATURES, MURKY ENGINE OIL DUE TO MIXING WITH COOLANT, HEAVY SMOKE FROM THE EXHAUST. THIS SEEMS TO BE A WIDER PROBLEM IN MANY OF THE DUKE 390 FROM WHAT WE HAVE READ ONLINE FROM OTHER DUKE 390 OWNERS. THIS WAS A MANUFACTURING DEFECT IN SOME OF THE MODELS.

From owner reports, verbatim
WHEN IN MOTION, AND GEARING DOWN, AS I PULL IN THE CLUTCH THE RPMS DROP. AS THEY DO, THE BIKE WILL INTERMITTENTLY STALL. THIS IS A CONTINUOUS ISSUE. THERE IS NO DIFFERENCE BETWEEN RUNNING COLD OR HOT. ALSO, THIS BIKE WAS JUST BOUGHT FROM PREVIOUS OWNER. THE TITLE IS NOT YET SIGNED OVER TO ME.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
