I have seen a number of answers here so I did some research.
First any engine will wear internally at an accelerated rate at temperatures
below 180 degrees F. 180 degrees is where the wear rate is negligible or
at least that is what I have always read.
As the temperature rises you run into the problem of rubber seals and the
engine oil breaking down. This starts around 250 degrees F. This is a
danger zone; oil break down means engine wear and possible destruction.

Automatic transmission fluid works longest at 175 degrees F and it degrades
rapidly as the temperature increases.

Today's engines generally run with 195 degree F thermostats or a little
more; I believe this is mostly for emission reasons.
Obviously you want to know what your engine temperature really is; use a
thermocouple, thermometer or IR reader to obtain this so you know what it
really is compared to what the gage indicates. My thoughts are that if the
engine in the Tiger is running around 180 to 200 degrees with 220 the max
under extreme conditions everything should be OK.

We have the old argument about Tigers running hot, but how hot is too hot?
At what temp does the engine start to get damaged?
