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 65C (149F) and 95C (203F).The switch-off temperature is adjusted automatically and is always 1C (34F) 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.
