The KTM Radiator Fan is a cooling upgrade designed to move more air for better engine cooling while adding digital control and temperature visibility. This PowerParts component (part number A46035941044) is aimed at riders who want more consistent cooling performance and the ability to monitor temperature during operation.
With an adjustable, variable switch-on temperature between 65 °C and 95 °C, it allows the cooling strategy to be tailored to conditions and preference. The fan switches off at 1 °C below the selected switch-on temperature, helping maintain a stable operating range without unnecessary cycling.
Engineered to provide more air, this radiator fan supports improved heat management by increasing airflow through the radiator. The result is better cooling of the engine, helping maintain performance when conditions demand more consistent temperature control.
Digital control adds an added layer of precision to cooling operation. The current temperature can be read at any time, allowing quick checks during use and making it easier to understand how the cooling system is responding in real time.
Switch-on temperature is variable between 65 °C and 95 °C, letting the activation point be set to match riding conditions. Switch-off occurs at 1 °C below the selected switch-on temperature to help keep temperatures steady once the fan has been triggered.
Comfort
Designed as a KTM PowerParts radiator fan, this unit focuses on improved cooling capability by delivering more airflow and supporting maximum performance. By providing better cooling of the engine, it targets situations where consistent temperature management matters, while keeping the operating approach straightforward through fan-driven airflow.
Visibility
This radiator fan adds a digitally controlled approach to cooling. Current temperature can be read at any time, and the switch-on temperature can be selected anywhere between 65 °C and 95 °C. Once active, the fan switches off at 1 °C below the chosen switch-on temperature, creating a clear, repeatable control behavior that can be set to preference.
