Mind you, they often have more than one now,

Inlet air temperature gauges are used by ECUs, I do know that - don't
suppose it's a bad idea to let it know about coolant temperature either.
<heh> Make it *properly* intelligent, and prevent the driver flogging
the beast until it's warmed up, that'd be the way.

Well, there's usually intake, coolant, oil and ambient sensors nowadays.
There's even altitude as well. Mine has even got an exterior temp
sensor, interior temp sensor and a sunlight sensor too.

The average temperature gauge seems to be built into the thermostat
housing where there's no chance of the coolant getting heating up
without the pump running. It seems to be standard.

I must admit, I haven't seen many bikes with temp gauges - I've owned
two with liquid cooling, and neither had one.

Not even an over-temperature idiot light? Rebecca's SV650's got one of
them.

Nope. Neither the BMW K100 (some of the later 16v models did) I had, or
the FJ1200, had any kind of temp warning.

Trouble is there's too many ways to do this,

<puzzled> What makes it trouble, there being lots of ways of doing it?

The trouble comes when they put them in the wrong place in the event of
a failure.

and they'll all have their
reasons why they did it a certain way.

Convenience is the obvious reason for putting it where it is on my
bikes. I don't suppose they thought about needing to indicate cooling
system failure. I often get the idea that jobs like `designing in that
sort of thing' are given to the spotty youth on the design team, the one
who's just left uni.

You do get that impression don't you.
