Headset Bearings
Dimensions (Measured as a set, i.e., pressed race, caged bearings, fork crown race.
Top Bearing Set ID=26 mm OD=47 mm Width=15 mm (verified with caliper)
Bottom Bearing Set ID=30 mm OD=55 mm Width=17 mm
Note: The lower bearing set I got from my mechanic didn't have the pressed race (cone), thus no caliper verification.
OEM numbers stamped on 'fork crown races'/'cups' bearing sets:
Top: Koyo SAC2647-1
Bottom: Koyo SAC3055-1
I am working on a cross reference for tapered bearings. All Balls is one.
BTW the Honda 1995 CBR600RR uses the exact same headset bearings.
