Radiator fan (cut in) !!

 Hi guys, anyone with a newish m800 / vz800 that can tell me how often the rad fan kicks in, whenever I stop or am in slow moving traffic it seems to kick in, if others do then that's fine but of all the bikes I've had I've never had one that the rad fan is on so often, I'm not having any overheating probs so I hope someone will tell me this is normal, the bikes a 2013,  

Mine does very similar John so don't fret over it ok.

Thanks Tex  

The fan cut's in when the internal water temperature reaches around 105c, all sounds good to me John in this weather.  

  

 Cheers guys, my minds at rest    

+1 mines the same, thought it was a problem at first  

+1 mines the same, I thought it was a problem at first too,been coming on all weekend 

Since fitting the temp gauge on mine, I've noticed that under normal riding conditions, a constant 50-70mph with the wind blowing through the rad, the bike runs at around 70-80c, as soon as you hit traffic of any description and the pace goes up and down? operating temp start to climb into the 90s quite quickly and the fan kicks in around the 105c mark (as Dave pointed out) but soon reduces by 3 or 4 c, where it knocks off again, I should imagine in this good weather we're having? any sort of slow riding (Cruising) will have the bike not far from the 105c mark so it's quite normal to hear the fan going on and off, the Red light on the dash doesn't come on till 120c so there's no problem unless that shows it's face, 'neat' coolant has a boiling point of around 180c (from memory) so unless there's a problem with circulation all should be good and the sound of the fan coming on set your mind at rest that it's doing it's job   

ps. You won't hear much of it in winter riding, so it's a nice sound in 'summer' to put your mind at rest that it still works.
