THE BIT THEY DIDN'T PUT ON THE BOX.
The smallest bearing. The biggest cheek.
Motorcycle brands use these universally inside wheel hubs. Sourced inside an OEM box (e.g., Honda/Yamaha), they cost £18–£25 each. Buying the exact same high-precision SKF or NSK 6203-2RS bearing from an industrial power transmission supplier costs £3–£5.
SO WHAT'S THE CATCH?
Suffix, clearances, lubrication, tolerance and application matter.
