The KTM Duke motorcycles are equipped with a safety feature called a sidestand switch, which is designed to prevent the motorcycle from starting while the side stand (also known as the kickstand) is in the down position. This safety feature is intended to prevent accidents that could occur if the rider were to engage a gear and start moving while the side stand is still down.
When the sidestand is down, it activates the sidestand switch, which sends a signal to the motorcycle's electronic control unit (ECU) or engine management system. The ECU recognizes that the sidestand is down and prevents the engine from starting or running.
This feature ensures that the sidestand is in the raised position before the engine can be started. It serves as a safety measure to avoid potential accidents that could result from riding with the side stand still engaged.
If your KTM Duke bike is not starting when the sidestand is down, it is likely functioning as intended. To start the bike, simply raise the sidestand to its upright position, ensuring that it is fully retracted, and then try starting the engine again.
