Indispensable in extreme conditions, this fan ensures more air, better cooling and maximum performance. It's in your own hands: The digital control allows you to adjust the switch-on temperature to the present conditions and to read off the current temperature at any time. The freely selectable switch-on temperature is between 65 °C (149 °F) and 95 °C (203 °F).The switch-off temperature is adjusted automatically and is always 1 °C (34 °F) below the selected switch-on temperature. For mounting on 2-stroke models, the additional wiring harness 777.11.979.000 is required and the Y-distributor 777.11.979.010 is necessary for the 4-stroke models.
