1977 Honda CB750K · Steering Hardware & Dampers Buying guide

Separate steering bearing work from stem and fork-cap hardware

The bearing kit supplies upper and lower tapered bearing races. Stem nuts, washers and bolt sets have separate quantities, while the fork-cap products belong to the forks. Match each part to its location before adding it to the order.

Inspect the steering assembly before selecting hardware

A bearing conversion kit and an external stem nut address different components. Use the fitted assembly and parts diagram to identify what requires replacement. The featured nut’s 30mm measurement is its hex size; it should not be used as a bearing dimension or thread specification.

Read each hardware quantity rather than assuming a full kit

The chrome stem nut and matching washer are individual listings. The linked bolt set contains two bolts and two washers. Keep those contents clear in the order, and use the appropriate service manual for the assembly and adjustment procedure rather than guessing a fastener torque.

Questions before you order

Does the bearing kit include a new chrome stem nut?

Its description names upper and lower tapered bearing races. The chrome nut and washer are separately listed parts. Check the bearing kit contents and the installed steering hardware before adding replacements to the same order.

What does 30mm mean on the stem nut?

The stem nut listing identifies a 30mm hex size. That describes the wrenching flats, not the bearing diameter. Match the Honda reference and the fitted hardware rather than selecting a bearing or thread from that number.

Are fork-cap O-rings steering bearing seals?

No. The linked pair serves the fork caps and has its own stated reference. Those O-rings should not be treated as components of the steering bearing conversion kit, even though both products appear in this category.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
