After market wheel bearings

SKF make good bearings - just as good as any other good manufacturer out there.
Buy bearings with protective seals built in - they last longer and keep cr-p out of the grease.
My 2c worth.
When replacing bearings, PUT THEM IN THE FRIDGE/FREEZER OVERNIGHT before doing them.
They'll go in much easier because they will shrink a micron or two

DO NOT use "C3" clearance bearings for the bike - C3 is for continuous high speed running - ie 15,000 rpm + ( and that would be wheel rotation speed, not crankshaft - haha )
Just get standard clearance SKF bearings.

The normal diameter of a motorbike wheel/tyre is around 60cm
60cm x 3.142 = 1.885 meters per revolution
530.5 revolutions per min = 1 km per min = 60 kmh
2652.5 revolutions per min = 5 km per min = 300 kmh
At 2652.5 revolutions per minute you are hardly even stressing standard bearings never mind trying to get C3 bearings up to the correct running temp for correct clearance.
Stick with standard spec - they will last longer.
I'll get my engineers anorak now and leave the buliding - haha
