Why KTM Motorcycle engine doesn’t crank (E-starter)?
- C
  Chris MorrisonAug 21, 2025
  If your KTM Motorcycle engine doesn’t crank when using the E-starter, it could be due to a few reasons. First, make sure you haven't made an operating error by ensuring the emergency-OFF switch is turned on (Australia only). Next, check the fuse; a blown fuse could be the culprit. You can replace the fuse in the starter relay after dismounting the left paneling and the filter box cover. A discharged battery can also prevent the engine from cranking, so recharge the battery and investigate why it discharged. Low outside temperature can also affect the engine; in this case, try starting the engine with the kickstarter.

  If your KTM Motorcycle engine gets too hot, refill the cooling liquid and check the cooling system for leaks. You can also ride faster to increase airflow. Make sure to bleed the cooling system and clean the radiators with a water jet. If there is foam, replace the cooling liquid with antifreeze. Also, inspect and replace bent cooling hoses and check the thermostat.
