Hi,
does any one have the universal number for the FZR 6 steering head bearings or better still are they the same size as these :-

THE TOP BEARING IS 47mm o/d x25mm i/d,
THE BOTTOM BEARING IS 55mm o/d x 30mm i/d
Thanks

George just went and measured and this is what I got. Top bearing is 25 ID and 43.4 OD. Bottom bearing is 29 ID and 50.5 OD. Now my OD might be slightly off. Could be 43 and 50, but I know my ID is dead nuts on the top bearing. My bottom bearing was pressed on so I couldn't measure the inside but the the stem right above was 29. Since the bearing has to be pressed on maybe it flares right after that to 30?

TK,
Hmm the bearing company is giving me 25 x 47, 52,60 mm only (pt number 32005X )
30mm i/d gives 62,72,55 (pt number 32006X)
I take it these are what I imagine single roller taper bearings NOT ball races ?
Thanks

Yup single roller taper bearings. It's all I got.
