A radiator cooling fan kit for KTM motorcycles designed to increase airflow and help maintain engine performance in extreme conditions. Riders gain confidence from more consistent power and a readable temperature display with the KTM Radiator Cooling Digital Fan Kit. Is this the right upgrade for specific KTM models and demanding riding conditions?
⚡ At a Glance
- • Cooling Performance: Increases airflow to the radiator, helping maintain better cooling and preserve engine power under heavy use
- • Best for: Off-road KTM riders and racers who push bikes in hot or sustained high-load conditions
- • Not ideal for: Owners of KTM models that already use a suitable OEM fan where no extra wiring or harness is desired
Electric radiator fan with a digital control unit for temperature management. Designed to add airflow and a readable temperature display for selected KTM models.
Precise temperature control - with a digital control unit
Digital control allows selecting the activation temperature between 150 and 203 degrees Fahrenheit, and the deactivation temperature is automatically set to one degree Fahrenheit below the chosen activation point. A readable temperature display shows the current temperature at any time.
Tailors fan activation to prevailing conditions for steady engine cooling, reducing the risk of power loss due to overheating.
Low electrical load - thanks to a 30 watt, 12 volt design
The fan draws 30 watts from a 12 volt electrical supply, a modest power requirement compared with many high-capacity aftermarket fans. Electrical demand remains limited while delivering continuous airflow when active.
Limits strain on the bike's electrical system while delivering effective cooling, suitable for bikes with standard 12V systems.
Wide fitment flexibility - with model-specific harness options
Fitment covers a broad range of KTM models across multiple years, with certain bikes requiring additional wire harnesses part numbers 77711979000 or 77735045000 for proper installation. Compatibility notes list many XC, EXC and XC-W variants.
Offers compatibility across many KTM off-road and competition models, while harness options allow installation where factory wiring differs.
✨ The 4 Key Reasons for KTM Radiator Cooling Digital Fan Kit
