I just had my rear wheel off to do suspension work and checked all my wheel bearings and they are good. The flange bearings are KOYO brand and Im just wondering if these are the stockers. Just trying to determine if the P.O. had swapped them out. The wheel bearings are NTN so im assuming something has been changed but i dont know what brand were installed from the factory. TIA

I just looked through my stock of new spare bearings, and at my prior sets of driven flange bearings...

Driven Flange Bearings
91052-KZ4-J21 - 6905RS - Originals in bike from factory: Koyo brand
91052-KZ4-J21 - 6905RS - First set of replacements: Koyo brand (changed proactively even though there was no failure underway)
91052-KZ4-J21 - 6905RS - Current installed set: unknown (they're in the bike!)
91052-KZ4-J21 - 6905RS - Current spare set: Koyo brand

Front Wheel Bearings (qty 2)
91053-MCS-G01 - 6205UU: Nachi

Rear Wheel Left (disk side):
91052-MAE-004 - 6204UU: NSK

All the above were received in Genuine Honda OEM sealed bags. These spares were purchased 3-6 years ago (across several orders). I've owned the bike since new.

The manufacturers buy those kinds of parts from whoever can supply them to meet spec at the price they want to pay.
