From what I can tell, the 62/32-2RS size (32X65X17) is an oddball used only in powersports, and Koyo NTN, and KML may be the only manufacturers.
All the usual industrial bearing manufacturers I checked don't make this size (if I missed one, post a purchase link), and most industrial suppliers (McMaster, Zoro, Grainger) do not stock this size. (Fastenal lists one option, but with no brand and no stock.)
Koyo is a Japanese brand with plants all over the world, including China. I know they're OEM on Toyota and Suzuki, so I'd strongly suspect the OEM bearing is a Koyo. The OEM Koyo bearings I installed recently on my Toyota were Koyo made in China. They're high quality stuff, wherever they're made.
KML seems to be a Chinese brand and while they're a step down, they are also perfectly fine bearings in this application.
I have never once seen a motorcycle wheel bearing failure caused by defective or low-quality bearings; bearings almost always die because they were installed incorrectly.
Some die later in life because the seals wear out or were abused. Water and/or dirt can get in if you do things like ride in deep water, park for years with water dripping in, using a pressure washer, etc.
Most motorcycle wheel bearings are repurposed industrial bearings made to run at incredibly high loads and temperatures, and at many thousands of RPM. They're absolutely loafing out there in the cool breeze in lightly loaded relatively slowly turning motorcycle wheels.
I've installed the KML bearings sold in the convenient All Balls kits many times with zero issues.
And I'll also admit I've screwed up a few times, damaged the bearings I'm trying to install, and had to find a replacement.
