  If your KTM Motorcycle engine doesn't turn when you press the starter, possible causes include an operating error (ensure you're following the correct start procedure), a discharged battery (recharge it and check for the cause of discharge), blown fuses (replace fuses 1, 2, 3, or 4 or the main fuse), a defective ignition/steering lock or emergency OFF switch (have it checked), a defect in the safety start system (have it checked), or a missing ground connection (check the ground connection).

  If your KTM Motorcycle engine turns but doesn't start, the issue might be an operating error (ensure you're following the correct start procedure), a blown fuse 4 (replace it), a disconnected fuel hose coupling (reconnect it), an oxidized socket connector of the cable harness (clean and treat it with contact spray), or a defect in the fuel injection system (requires reading the error memory with the KTM diagnostics tool and correcting the fault).

  Your KTM Motorcycle engine might overheat due to several reasons: too little coolant in the cooling system (check for leaks and coolant level), very dirty radiator fins (clean them), foam formation in the cooling system (drain and refill/bleed the system), a buckled or damaged radiator hose (have it changed), a defective thermostat (have it checked), a blown fuse 5 (replace it), a defect in the radiator fan system (have it checked), or air in the cooling system (fill/bleed the system).

  High oil consumption in your KTM Motorcycle can be caused by a bent engine vent hose (straighten it or replace if needed), an engine oil level that's too high (check and adjust the level), or engine oil that is too thin (change the oil and filter, and clean the oil screens).

What to do if KTM Motorcycle engine turns only if the clutch lever is drawn?

  wilsonjudithSep 1, 2025
  If your KTM Motorcycle engine only turns when the clutch lever is drawn, it's likely because the vehicle is in gear. Shift gear to neutral. It can also happen if the vehicle is in gear and the side stand is folded out. Shift gear to neutral. Another possibility is a defect in the safety start system, which should be checked.
