1971 Honda CB450K · Steering Hardware & Dampers Buying guide

Identify stem hardware and bridge washers by their own references

The stem nut references 90304-415-000 and states a 30mm hex. Bridge washers instead use 53235-300-000, and the individual stem washer uses 90503-283-000. The bolt-and-washer set supplies two of each with different references again.

Keep the washer references with their actual components

The top bridge set, individual stem washer and bolt set have separately identified washer references. The bolt set supplies two bolts 92101-10040-0A and two washers 94102-10000. Compare the hardware removed and location served rather than treating all washers in the steering selection as the same component.

Use the nut hex size for the stated feature only

Chrome and black stem nut descriptions give 30mm hex and reference 90304-415-000, but do not state mounting thread dimensions. Check the original nut and installed stem, particularly after a conversion. Their finish difference is not evidence of a different thread specification or confirmed fit to every altered stem.

CB450K buying questions

Are the two steering conversion kit listings different specifications?

They carry identical descriptions and the same part number, including upper and lower tapered bearing races. The “(2)” title suffix does not document a different bearing size or supplied quantity. Compare the installed assembly with the actual product details.

Does the bearing kit confirm every seal, washer and fastener supplied?

Its description specifically states upper and lower tapered bearing races without an itemized inventory of every seal or fastening component. Identify the parts required for the fitted assembly and confirm any additional contents before treating the kit as the complete repair order.

Can the bridge washers be ordered instead of the bolt set’s washers?

The bridge washers use reference 53235-300-000, while the bolt set’s washers use 94102-10000. The individual stem washer has another reference. Compare the actual part needed; shared steering application does not establish interchangeability among these washer products.
