1977 Honda CB750F · Fork tubes, springs, seals & boots Buying guide

Choosing fork parts

Identify the fitted fork before selecting tubes, seals and internal parts. Confirm replacement-tube dimensions and compare the supplied parts and fitting requirements of each spring or damper option.

An oil lock piece for later forks

The genuine Honda oil lock piece replaces 51432-371-003 and lists the 1977–80 CB750F. It is sold individually. Match the reference and the fitted fork’s parts information before ordering; it is not described as a universal fork component.

Separate seals and retaining parts

Fork seal set 27-1007 is listed as 35 × 48 × 10.5 / 11 mm. Stopper-ring pack 73-0940 contains two rings replacing 51447-KL4-951 and is described as fitting above the seals. The separate dust-boot pair 27-1081 lists the 1977–78 F.

Fork questions

Do the progressive springs include their spacers and washers?

Spring set 27-1078 includes two springs together with the required spacers and washers. Account for those supplied parts before ordering separate spring hardware; this package does not establish the parts required for a separate damper-valve conversion.

Do the damper valves need drilling?

The supplier requires damper-rod drilling and recommends mechanic installation. Some applications may need an additional tube spacer; the listing does not say this is required for the 1977 F. Confirm the fitted fork and required parts before ordering.

Not sure which part you need?

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