Well, I’ve been riding liquid cooled bikes since the mid-1980s with no “guards” and haven’t had a single failure event, ever. I do inspect my bikes after every ride and straighten any fins bent by the bugs that hit them. I suppose if you’re prone to riding until something breaks, then you may have an issue at some point. There is very little margin on the V4 heat exchangers. Ask a serious Ducati race team about cooling. These aren’t dirt bikes eating the rooster tails of the fast guys in front.
People are stupid and can do their own thing as desired. Hell, there are guys and girls cutting off their generalist in a futile attempt to be something else, so they can certainly configure their shot however they want.
There has been no change in running temp on my bikes running radiator guards, ever. I haven't done any scientific comparisons but the temp was fine before installing them and afterwards the running temp while riding was exactly the same, and my climate isn't chilly.
I have always run rad/oil guards because you just never know when someone in front is going to flick up a stone or whatever that can end up leaving you stranded possibly in the middle of nowhere. The only failure i've ever suffered was an oil cooler on a monster that leaked oil enough that my rear tyre felt awful so i pulled over to check it, that was when they put it down under the horizontal cylinder, right behind the front wheel, stranded, needed a van to collect me and the bike, and a new cooler, i'm lucky the oil didn't cause a fall.
Some people do more harm than good though, i've seen all sorts of things used as guards and often the ties that go through the fins are so tight they tear them and distort the cooling tubes, but if you invest in a quality product and install it properly from my experience there are no down sides.
