1975 Honda CB400F · Steering Hardware & Dampers Buying guide

Nut, washer, then the races

Order the 30mm nut and the washer as two parts. Buy one bearing kit for the upper and lower races. Do not buy both kits until you compare them, because the descriptions match.

Black and chrome are the same Honda number

Both nuts replace 90304-415-000. Chrome is the 30mm hex called out above. Black is the other finish. The washer is still separate.

No damper is in this category

You can order the nut, the washer, and a bearing kit. Fork-cap O-rings replace 94608-50000 as a set of two and belong on the fork caps, not on the stem.
