    A working solution to what to use to replace NF4 steering head bearings (RS125 88-94) is to use one of each of 91016-KT8-005 and 91015-KT8-005 bearings from a CBR900 they will need to have 4mm removed from each of the cones any good engineering workshop can do this.

    I hope this is of help to others Cheers.
    So this is
    CBR900
    All Balls Steering Head Bearing Kit 22-1020
