just to adresse the temp 230(110 celcius) over 120 celcius(you will have to find the fahrenheit that matches) the oil starts braking down, that means have oil been over that temp you must change it or there is a big chance off engine fail.
it does not matter is you have the high super gold version all oils starts braking down at 120 degress celcius and over.
my 2019 model skoda fabia does go to a litle over 105 degress celcius, when it´s over 25/30 degress weather, if i could choose i would never go over 95 degress celcius in oil temp.
and i do think an oil cooler should be mandetory from the factory, when selling bikes and cars in arizona and texas.
i like the hoses on the ultracooler

They have oil coolers from the factory….the Harley development/engineering test track is in the desert of Arizona. Ride your bike and don’t worry about ghosts and goblins. The engine can handle more heat than you can handle riding it. If adding a second oil cooler helps you sleep at night, so be it. If leaving a light on helps you sleep at night…so be it.

I have never once worried about my engines failing due to oil breakdown on any of my dozen or so Harleys…EVOs, Twin Cams and M8s. Run a heavy weight synthetic that meets factory specs and ride!
