Why is my KTM 2011 990 Supermoto T USA engine overheating?
- A
  Angela AllenAug 18, 2025
  If your KTM Motorcycle engine overheats, it could be due to several reasons. It might be caused by too little coolant in the cooling system, so check for leaks. Dirty radiator fins can also cause overheating, so clean them. Other potential causes include foam formation in the cooling system (drain the coolant), a buckled or damaged radiator hose (change the hose), a blown fuse 4 (change the fuses), a defective thermostat (check the thermostat), a defect in the radiator fan system (check the fan system), or air in the cooling system (fill/bleed the system).

  If your KTM Motorcycle engine has too little power, the possible reasons are: the air filter is very dirty (change the air filter); there is a defect in the fuel injection system (read out the fault memory using the KTM diagnostics tool); the ignition curve for low octane fuel is activated (refuel with fuel with an octane rating of 95 or higher).

  If the ABS warning lamp lights up on your KTM Motorcycle, it could be due to a large difference in wheel speeds between the front and rear wheels. To resolve this, stop the vehicle, switch off the ignition, and then start it again. Alternatively, there may be a malfunction in the ABS, in which case you should read out the ABS fault memory using the KTM diagnostics tool.

  If your KTM Motorcycle engine turns although a gear is engaged, it may be due to a defect in the safety start system, so check the safety start system. It could also be that the coupling of fuel hose connection is not connected, so reconnect it. Another possibility is that the socket connector of wiring harness is oxidized, so clean the socket connector and treat it with contact spray.
