I've been impressed at the ambient temperature reading on the FZ-10, it seems to be very accurate. On my prior FZ1 the temperature readout was wildly high and pretty useless. But the FZ-10 looks pretty close to reality. I was out yesterday with the forecast high of 93 deg and the temperature indicated on the panel was pretty close to that, and when the occasional clouds came along the temp would drop to about 87 which I could feel on the bike through the mesh jacket. I assume the temperature is taken somewhere close to the air box which would be higher than the actual ambient temperature due to the engine heat, evidently Yamaha has put a good correction factor on the reading. With an outside temp of 93 deg the coolant temperature was in the 168 deg area at a speed of about 75 mph, but it sure pops up in a hurry when you slow down or stop.

Your getting temps of 168 at 93 degrees? Damn. I'm seeing 215+ at 80 degrees non-highway riding. I was actually questioning the readout myself since it seems to jump up so high so quickly.

At a constant highway speed of 75+ mph yes, I'm seeing coolant temps of around 168 deg on a hot summer day. In traffic that is another story, I've seen temps as high as 224 deg stopped at an extended red signal, but it drops pretty fast once you start moving again. |

Yea that's probably the one positive! It drops pretty fast once you start moving.

Tune keeps the temp down

Yes, I have heard that from multiple sources. |

Even before the tune I felt that the bike was pretty efficient at dumping heat when moving. Overall it's the coolest running bike I've owned. In traffic it's as hot as any other though. I get temps around 168-170 when moving even in the summer.

I commute everyday in Florida and surprisingly on the highway she's at 170 in 95 degree heat over 70mph. 224 is the norm when stopped but quickly decreases with airflow.
I noticed my coolant level dropped under half so I topped her off and I'm tempted to crack the bleed valve to see if there's any air.
Cruising around Daytona during bike week roasted the jewels!

I'm glad I came across this thread as it provided some much needed reassurance. The MT-10 is the first bike I've had that's had an engine temp reading. My readings are comparable to others here. Riding 70+ MPH in 85 degrees, it will settle in around 168-170 degrees. Unfortunately, my ride home from work often has dreadful traffic w/ me averaging 15-20 mph in stop and go for 10 miles. In these conditions, the temp quickly rises to 225 and alternates between that an 210 as the coolant/fan kicks in. The heat wash from the engine at these temps is almost unbearable when just wearing jeans. I've not had that issue my other bikes (Street Triple, V-Strom 650, V-Strom 1000). Any suggestions on how/whether to address? Sounds like a tune could drop the temp when the fan comes on, but that probably comes at a trade off. Perhaps I just invest in some asbestos riding pants...

Temps seem normal in that kind of conditioning. Unfortunately I don't think there's much you can do. Most of the heat that leaves the engine is through radiation into the surrounding air. When you're moving at a good speed, this air is quickly replaced with cooler air as you travel. But when you're staying still or not moving very fast, that radiant heat sticks around the engine and causes that feeling. The fan doesn't cool down the engine. The fan cools down the coolant which circulates throughout the engine to bring heat out with it. I wouldn't expect the fan turning on much earlier to have a drastic effect in traffic driving. |

On my recent 2-day trip, I was surprised to see 170 at 104ºF ambient, and speeds of 85/90 in the middle of nowhere. I wish my bike had an oil temperature gauge instead; it's more important IMO. Since we have an air-to-oil cooler, oil is probably hotter than the coolant at high ambient temperatures, which is fine. But in winter/cool weather, it'd be the opposite, and that's not good for the engine, especially if you like to rev it high. My ex-2012 Grand Sport Vette, with a 195ºF thermostat, it only showed oil temperature in the low 160s in winter, with its air-to-oil cooler (GM changed it to a proper coolant-to-oil the following year, which heats and cools the oil to an acceptable range). Can't imagine how low oil gets on our bikes with coolant at only 167ºF. Optimal oil temperature is 212ºF. Wonder why Yamaha decided on such a low temperature thermostat; I'd like to know. Glad I'll never use this bike in cold weather  . |

The gauge is right in front of the air intake box.
I saw it there the other day
