Hello all,
I'm replacing the wheel and head bearings on my '76 CB750F. Here is what I have found re. the bearing sizes and Honda part numbers.

Front wheel bearing x2
Honda Part Number per Western Hills: 96150-63020-10 BEARING, RADIAL BALL 6302UU
Common size: 6302
Dimensions: 15mm x 42mm x 13mm
2RS or 2RSH (after 6302)=Rubber seals fitted to both sides of the bearing

Rear wheel bearing brake side
Honda Part Number per Western Hills: 96140-63040-10 BEARING, RADIAL BALL 6304U
Common size: 6304
Dimensions: 20mm x 52mm x 15mm
2RS or 2RSH (after 6302)=Rubber seals fitted to both sides of the bearing

Rear wheel bearing drive side
Honda Part Number per Western Hills: # 96140-63050-10 BEARING, RADIAL BALL 6305U
Common size: 6305
Dimensions: 25mm x 62mm x 17mm
2RS or 2RSH (after 6302)=Rubber seals fitted to both sides of the bearing

Head bearings
Upper: 26mm x 48.5mm x 15.2mm
Lower: 30mm x 50mm x 14.4mm


Using these sizes, you can buy quality bearings made by SKF, Timken, FAG, Koyo and others for better prices than Honda OEM or Chinese "balls" bearings.
Stainless steel seals and ceramic balls can be had as upgrades as well.
