Why does my KTM Motorcycle engine turn although a gear is engaged?

  Kristin SmithSep 10, 2025
  If your KTM Motorcycle engine turns although a gear is engaged, there may be a defect in the safety start system, which requires professional inspection. Alternatively, it could be an operating error, so follow the correct starting procedure. It may also be that fuse 4 is blown, so replace the fuse. Another potential cause is that the coupling of the fuel hose connection is not connected, so reconnect it. Finally, the socket connector of the cable harness may be oxidized, so clean the socket connector and treat it with contact spray.

  If the KTM Motorcycle engine does not turn when you press the electric starter button, it may be due to several reasons. First, ensure you are following the correct starting procedure. If that's not the issue, the battery might be discharged and needs recharging, and you should identify the cause of the discharge. Also, check if any of the fuses (1, 2, 3, or 4) or the main fuse are blown and replace them if necessary. If the problem persists, the ignition/steering lock, the emergency OFF switch, or the safety start system may be defective and require professional inspection.

Why KTM 690 Duke Motorcycle engine turns but does not start?

  Margaret JacobsonAug 26, 2025
  If your KTM Motorcycle engine turns over but doesn't start, several things could be wrong. It could be an operating error, so carry out the start procedure. Fuse 3 could be blown (change the fuses). The fuel hose connection might not be connected (connect it). There could be a defect in the fuel injection system (read out the fault memory using the KTM diagnostics tool). Avoid opening the throttle while starting and ensure the air filter is clean (remove and install the air filter). The fuel filter may be very dirty (check the fuel pressure).

  If your KTM Motorcycle battery is discharged, it might be because the ignition was not switched off when the vehicle was parked (recharge the battery). Another reason could be that the battery is not being charged by the alternator (check the charging voltage and the quiescent current).

What causes my KTM 690 Duke Motorcycle engine to overheat?
- B
  Bobby ChandlerSep 6, 2025
  If your KTM Motorcycle engine overheats, it could be due to several reasons. Check the coolant level and inspect the cooling system for leaks. Clean any dirt from the radiator fins. If there's foam in the cooling system, drain and refill/bleed it. Inspect the radiator hose for buckling or damage and replace if necessary. The thermostat may be defective and needs checking (opening temperature: 70 °C (158 °F)). Check if fuse 5 is blown and replace it. The radiator fan system may also be defective and require inspection. Finally, ensure there is no air in the cooling system, and if there is, fill/bleed the cooling system.

- T
  Travis GainesSep 7, 2025
  If your KTM Motorcycle engine has too little power, the fuel filter might be very dirty and needs to be changed. Alternatively, there could be a defect in the fuel injection system, which requires reading the error memory with the KTM diagnostics tool and correcting the fault.

Why does my KTM 690 Duke Motorcycle have high oil consumption?
- A
  Alison WheelerAug 31, 2025
  High oil consumption in your KTM Motorcycle could be due to a couple of reasons. The engine oil level might be too high, so check it. Alternatively, the engine oil could be too thin (low viscosity), in which case you should change the engine oil and filter and clean the oil screens.
