What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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.
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.
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.
