The KTM Radiator Fan is a KTM PowerParts cooling upgrade designed to increase airflow through the radiator for better engine cooling. This fan focuses on controlled, performance-oriented operation, making it a strong choice for riders who want cooling support with adjustable temperature management.
Part number A49035941044 features digital control with a selectable switch-on temperature between 65 °C and 95 °C, and a switch-off point set 1 °C below the chosen switch-on temperature. The current temperature can be read at any time, helping riders monitor conditions while the system delivers more air for maximum performance. This product is listed for the models shown in the vehicle compatibility table.
A49035941044 uses digital control to manage fan operation based on temperature. Riders can set the switch-on point to match conditions and priorities, helping the cooling system respond with consistent, controlled fan engagement rather than a fixed activation point.
The switch-on temperature is variable between 65 °C and 95 °C, allowing the fan to be configured to come on earlier or later depending on preference. Once activated, the fan switches off at a point defined as 1 °C below the selected switch-on temperature.
This radiator fan setup allows the current temperature to be read at any time. That always-available temperature reading supports informed adjustments to the selectable switch-on setting and helps keep an eye on operating conditions while riding.
Designed to provide more air, the KTM Radiator Fan helps improve cooling performance by increasing airflow through the radiator. By supporting better heat management at the radiator, it contributes to better cooling of the engine and is positioned for maximum performance where consistent airflow can make a difference.
The fan is built around a digital control approach with a rider-selectable switch-on temperature between 65 °C and 95 °C. After switching on, the system switches off at 1 °C below the selected switch-on temperature, creating a clear operating window. With the ability to read the current temperature at any time, the system supports active monitoring alongside controlled fan operation.
