I Guess the Super Ténéré is just a Warm Weather Bike

Yeah, no experience on a motorcycle below the low 30s. In cars I’ve driven in sub-freezing weather the temp gauges have always come up to the normal range

I have noticed that my mileage goes down as with lower temps. Now with some really low temps my mileage has tanked.

This morning it was 25 degrees, I gave the bike lots of warm up time and headed the seven miles to work. My normal running temp is 167 to 175. I started at 169 and by the time I got to work it was down to 141.

I get to thinking does the bike have a thermostat and is it working correctly or do I have a sensor problem. So with a lot of windshield time to the first job, I decided to call the local dealership's service department and ask them.

Dealership "This is Tim, how can I help you?"
Me "I have a Super Ténéré and I was wondering if it has a thermostat?"
Tim "You have a what?"
Me "I have a XT1200Z"
Tim "What year is it?"
Me "2012"
Tim "So it's new ?"
Me "Ah, yes"
Tim "Let me ask the service manager................yes it has a thermostat, why do you want to know"

I explain my poor mileage in cold weather

Tim "What does it matter, how much longer are you planning on riding it this year ?"
Me "Until the roads get icy"
Tim, long pause then "Well, if your next tank's mileage is bad, bring the bike in and we will check the sensors"

I hope they don't let this guy work on the bikes.

So, now I just have to move to a desert so I can ride the bike. ::022::
This is the case for every ICE vehicle. In winter air is denser so the bike uses more fuel. The reward is more power.

Completely normal, motor's need more fuel when the temps drop or they won't run properly and, in some cases, if at all.
My GS was terrible when temperature would near 10deg C, it would constantly stall at lights and intersections till it was up to operating temp.
My S10 is good that was, rode it in -15deg C last fall and it ran well, engine temp came up like normal. The mileage might of suck but no stalling, so Yamaha may program the ECU to adjust for the Canadian northern climate on Canadian models and may not on models sold in the warmer climates.
Riding any motorcycle in such cold temps is retarded anyhow and dangerous, I won't be doing that again and could care less if the bike doesn't run in such cold temps.
Mine starts and runs like normal but its not going anywhere.

A little but not much for us where it freezes. Warm days in winter, like getting into the low 50s here now, do not result in suddenly getting back to summer MPG.
And if you log you mileage consistently you'll see it steps down in late Fall then steps up in Spring.

The reason is that the refineries change their gasoline blend to alter the Reid Vapor Pressure (RVP). The RVP is the point where the fuel molecules atomize. The atomization is more difficult in Winter so we get worse MPG.
