So I ride KX450s. I currently have a 2021 KX450, I’ve also had this same problem on the 19 & 20. The steering stem bearings last about a weekend (exaggerating) but they wear out super quickly.
Anybody have any tips or tricks on how to avoid this issue moving forward?
& for the love of God, yes I grease them for all the vitards that are going to ask.

38 hours on my 2019 and using Maxima grease without any issues.
And FWIW, I don't use a pressure washer, just Mr. Clean Multi-Purpose cleaner and one of those fire hydrant style garden hose nozzles.
be glad you dont have a yamaha they burn threw fork seals, front wheel bearings and steering bearings
My first sign of rust on these bikes is when you take the bike off the stand after it sits for a few days the bars will be locked straight until you break them free. It's downhill quickly after that and they get extremely notchy, to the point where it can be pretty scary to ride, especially on rutted straights. I was surprised it would feel it while riding to be honest!
It looks to me like there is not an adequate seal between the upper inner race and the steering stem, so water runs down and rusts the lower bearing. I've also seen water run out of the bottom of the frame, even after the bike has sat for a week, so maybe that could be causing it too? Either way, no amount of grease will protect against that.
Side note... How come the guys who brag about not using a pressure washing are always from California?

I heard just recently that Yamahas (?) have a thicker seal on their bearings. Maybe research that.
This was my first race on my 2021 😬
