Hub/wheel and forks don't have to match each other.
That's the little non-conical hub that's used in AT1, DT100, DT125, YZ100, MX125, MX175, and YZ125A (and some ag bikes).
That type of hub, in combination with an alloy mudcatcher was only fitted to YZ125A. The black hub confirms this.
The front brake plate is obviously from a non-leading axle bike - most likely the same YZ125A.
So the mystery only relates to the forks themselves.
