FWIW, nearly all TMs over $1500 have lifetime warranties on their motors. Meaning they will ship a replacement motor to you for free if you manage to kill yours. (As Lionel Sanders has done several times.)
I’ve actually never killed the motor on my Sole F80 - literally everything else on it wore out and needed replacing after 8 years of regular use in a garage (condensation in mornings = rust and killing electronics) EXCEPT the motor and frame, but Sole shipped me a new motor anyway for free since I was replacing the console and deck at one point.
The motor was actually pretty easy to replace for me, but I did need to buy a few larger wrenches to remove the larger bolts. Definitely easier than replacing the deck.
I’d say with most TMs over $1500, you can just forget about the motor - they’ll work, and in the chance you really are such a beast that you can kill yours repeatedly, they’ll send you a new one.
