Yea, that's the mystery here.
MSP HT motor was rated 2500W I believe.
MSP HS motor is just the MSX motor I believe. Rated at 2000W.

Looks to me that Gotway (I understand that these wheels are manufactured by GW for Chicway, right?) just gets rid of their leftover older parts (MSX 84V boards, 2.5 inch tires?) this way, by making Frankenstein wheels.
Maybe their latest firmware, adapted to 84V instead of 100V, gives the old MSX motor 2500W rating instead of 2000W. After all, that seems to be how they come up with their arbitrary power ratings.
