1978 Honda CB400TI Hawk I · Fork Seals & Dust Boots Buying guide

Order oil seals and outer dust protection separately

The seal dimensions describe the oil-sealing component; the 33 mm dust boots provide outer protection. Identify both worn parts and check for a changed fork assembly before selecting replacements.

Match the full seal size

The oil seal set carries three dimensions: 33 mm, 46 mm and 11 mm. Do not choose by the first measurement alone. Verify the existing seal and fork assembly, especially on a motorcycle whose front end has been replaced during its life.

Inspect the surfaces the new parts protect

New sealing parts belong in a service plan that also examines the fork tubes and surrounding components. Use the appropriate Honda service manual for disassembly, inspection limits and reassembly specifications. A seal purchase by itself does not diagnose the cause of oil leakage.

Buying questions

Are the dust boots supplied as a pair?

Yes. The separate fork dust-boot product contains two 33 mm boots and uses Honda replacement reference 91254-413-881. Compare the fitted boot profile if the fork assembly has been changed.

Which should I buy for an oil leak at the fork?

The 33 × 46 × 11 mm oil seal set is the sealing part to assess, while the dust boots serve the outer protection position. Diagnose the leak and inspect tube condition before deciding which service parts are needed.

Can I use these after a front-end swap?

Choose by the replacement fork’s requirements. The listed Hawk I application applies to the supported fork setup, so compare the full seal dimensions and dust-boot profile rather than ordering solely by the frame’s model year.

Not sure which part you need?

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