My R1 sits at about 78ish when moving; climbs to 105 when stationary when the fan kicks in.
As regards coolant I go with whatever the manufacturer recommends. On my crosser that's 50/50 ethylene glycol and water (the R1 gets serviced by
someone else, but antifreeze is used).
Race bikes can only use water, no antifreeze, because it's slippy as sin and they don't want it getting spilled on the track. And race
bikes generally don't get used in very cold weather 
If you do use water only, remember to drain the cooling system over winter or risk a cracked engine

My R1 runs between 80-90' depending on the ambient temp' (so I'd expect it to be around 80ish at the moment). It gets higher (95?)
on summer track days. Fan cuts in/out at 105/100' and it's quite happy sitting doing that.
I run 60% water, 30% a/freeze, 10%water wetter (improves conductivity). Don't run without a/freeze as it's also anti corrosive and lube
for the pump... and my workshop was down to -15c some nights this winter.
