Went on a ride 3 weeks ago, 150 mile round trip, including riding thru a couple communities. My max oil temp was in the 290’s.
Installed this cooler, repeated the same round trip, to test the cooler. I expected my max temp might go down to 260, I am in awe, my max temp was 225, and that was more from me testing the system at 90+ mph on the way home.
I recommend this cooler for any Harley!
