1983 Honda CB750SC Steering Bearings & Lock Nut

Inspect the steering stem and bearing arrangement before choosing parts for your 1983 CB750SC. The tapered conversion kit and head lock nut are separate purchases. A changed front end needs its own bearing and thread checks, even where the motorcycle’s frame and model identity remain original.

1983 Honda CB750SC · Steering Bearings & Lock Nut Buying guide

Check the existing steering bearing arrangement

The conversion kit includes upper and lower tapered bearing races. The thread-on lock nut serves a separate retaining position. Match both to the actual stem before planning the complete steering rebuild.

Review the conversion before dismantling

The bearing kit is a tapered roller conversion rather than a promise to duplicate every original bearing component. Compare the existing assembly and the package’s fitting instructions. A previously converted or replacement stem should be identified before the kit is chosen.

Match the retaining nut separately

The head lock nut replaces reference 90302-425-830 and is a thread-on part. Compare its position and thread with the piece removed. Use the appropriate service procedure for assembly and adjustment after the correct bearing and retaining components have been selected.

Steering Bearings & Lock Nut questions

Is the kit a tapered bearing conversion?

Yes. The kit includes upper and lower tapered bearing races. Check the current arrangement and full fitting requirements before ordering for the retained steering stem.

Can I choose the lock nut by appearance?

Compare its exact position, thread and replacement reference. A similar-looking steering fastener from another assembly is not sufficient evidence of fit, particularly after a front-end swap.

What if tapered bearings were fitted previously?

Identify the installed bearing arrangement and compare its dimensions and references before buying another kit. The motorcycle’s original application does not fully describe an earlier conversion.

Not sure which part you need?

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