Why is my KTM 690 Duke 2018 engine overheating?
- K
  Kevin WilsonAug 18, 2025
  Your KTM Motorcycle engine might be overheating due to several reasons. Check if there's too little coolant in the cooling system, inspect for leaks, and verify the coolant level. Dirty radiator fins can also cause overheating, so clean them. Other potential issues include foam formation in the cooling system (in which case you should drain, fill, and bleed the system), a buckled or damaged radiator hose (replace if necessary), a faulty thermostat (check it), a blown fuse 4 (replace it), or a defect in the radiator fan system (check it).

Why does my KTM 690 Duke 2018 have high oil consumption?
- B
  Benjamin TateAug 23, 2025
  High oil consumption in your KTM Motorcycle can stem from a few issues. A bent engine vent hose can cause this, so ensure it's properly routed without bends, replacing it if needed. Also, check the engine oil level, as a level that is too high can contribute to this problem. Lastly, using engine oil that is too thin (low viscosity) can also lead to high oil consumption, so change the engine oil and filter, and clean the oil screens.
