Otherwise, yeah, I've never seen a motor bearing have an issue at a temp below what would fry something else first.
I agree, but then you have to factor in track type as well. Meaning, my indoor clay off road track is small and tight by industry standards. I actually have trouble getting temps above the mid 140's without having a performance fall off on way or the other.
