It's a gray-colored set, made in China, but built to OE standards.
It cross-references with Yamaha/MBK numbers like 93399-999Y2-00, 93399-99940-00, 22F-23412-01, and others – so it's a direct fit for those applications.

If your steering feels loose, notchy, or makes clunking noises, these bearings are probably toast.
