Hello friends!
At what temperature does the fan kick off?
Today for the first time my fan started at around 217 deg.F and stayed on until 212. Is this normal. Also my bike reached 222 riding in town. Is this normal?
I have 110 miles on the ODO.

Thanks in advance
The temps you mentioned that turned the radiator fan on (217°) and then the temp that shut it off (212°) sounds about right.
Perhaps the temp hitting 222° when riding in town was because you were lugging the bike by not shifting up to the next gear.
I see the ambient temps were in the mid/high 60s so that may have contributed a bit as well.
The S10 is not at its best in slower traffic or stop-n-go.
Once you get better acclimated with your new S10 and how it rides things will definitely smooth up a bit with your input to
the bike regarding the throttle, clutch, shifting, braking, handling, etc., etc.. :cool:

+1. It's not so much slow city driving that causes her temps to rise, it's the time idling. But, city riding is the best way to learn the bike. Highway droning doesn't teach anything. With everybody complaining about the throttle twitchiness, I tried to figure out why mine is perfect, 'cuz I don't pay much attention to the actual mechanics of riding, I finally realized, that I'm using the clutch, more than the throttle for smoothness. Well, that and the back brake. So, apparently all those cone courses payed off. :D

I use the back brake and clutch waaayy more then others I have noticed. It really makes a difference.

Fan turns on at 105 degrees C and off at 100 degrees C. I use my S10 for parades a lot and have had a few times when the fan ran continuous and temp wouldn't go below 100 C, had to spray down the radiator with water to keep the temps from rising higher, IIRC the bike shuts down at 110 C.

If you complain about the S10 in the heat, you don't want to ride a Pan Am. Much hotter.

I had the fan activation temperature lowered when I had my ECU reflashed. It now switches on at 205F and off at 195F. I don’t think I’ve seen it go over 210F since the reflash, even in 100F ambient temperatures.

Same results with my flashed ECU.

I’ve seen mine on 114C once. Scorching hot day, 2 up and heavy traffic. Oh and a toast left knee… :confused:
I don't know what the temp was. Same conditions though. But I didn't notice any extra/concentrated heat . . . . it was summer in Texas . . . . everything was hot. I knew the fan was going to come on.

I recall Texas Tenere riders being a consideration with me just prior to my becoming an owner in 2012. Then as now their valuable thoughts and experiences offer ideal hot-climate, friendly opinions for people like me, the unfortunate occasional>rare deep south rider. We know our cold's always covered, but it's good to know just how well these things fare in the heat.

I can tell you that you definitely DON'T want to ride it up a steep mountain trail, or be stuck in traffic with the fan-blade locked to the radiator.
I don't know exactly how hot it got, but hot enough that the display went blank except for a giant warning: "TEMP-HI"

When I moved from the KZ1000 to the RT, I was concerned. The Beemer provided a lot more frontal protection from the elements, namely the wind. Wind flow in the summer is a must. And, I was wondering if I was going to be hotter on the RT than the KZ. As it turned out, all the bodywork that provided the protection from the elements . . . . kept the engine heat from radiating up. So, I ended up "cooler" than on the KZ.

The air temp readout on the ST13 wouldn't display above 122F. But when it reached 122F, would keep flashing until the temp dropped to <122F.

Took my left cowling off to have a look at the radiator. I bought this 2013 in October and just now getting to know the insides. When riding in the Fall I also noticed the fan kicking in at higher temps than expected. Makes me wonder why this cover is on the bottom 3rd of the radiator below the fan. It doesn't exactly hug the fins but it doesn't leave a lot of room for the air to do much work here. If it were removed or partially cutoff the next closest barrier would be the cowling which is a little further away and maybe allow more flow. Any thoughts?tempImageCZYUpe.jpg
