  If your KTM Motorcycle engine turns but doesn't start, it might be due to an operating error, a blown fuse 3, a disconnected fuel hose coupling, a defect in the fuel injection system, opening the throttle while starting, a very dirty air filter, or a very dirty fuel filter. When starting, do not open the throttle and carry out the start procedure. Reconnect the coupling of the fuel hose connection. Remove and install the air filter. You can check the fuel pressure.

  If your KTM Motorcycle engine does not crank when you press the electric starter button, it could be due to an operating error. In that case, carry out the start procedure. It may also be because the battery is discharged (recharge it), fuse 1, 2, or 3 is blown (change the fuses), the main fuse is burned out (change the main fuse), or there is no ground connection (check the ground connection).

  If your KTM Motorcycle only turns when the clutch lever is drawn, it's likely because the vehicle is in gear. Shift gear to neutral. It might also happen if the vehicle is in gear and the side stand is folded out. Again, shift gear to neutral.
