1980 Honda CB750K · Fork Tubes, Springs, Seals & Boots Buying guide

Distinguish fork seals, dust seals and stopper rings

The catalog lists the fork seals, external dust seals and metal rings as separate products. Each serves a different position in the assembly, so compare the removed pieces and the listed applications individually.

Parts to consider

Honda CB750 / CB650 / CB550 / CB500 Fork Seal Stopper Metal Rings (Pk/2) ~ Replaces 51447-KL4-951

Fork seal stopper ring pairTwo metal rings described for the position above the fork seal, with reference 51447-KL4-951.View part

Plan the sealing components as separate items

The dust seal description lists two pieces, and the metal stopper rings are a separate pair. The fork seal product has its own dimensions and application list. Compare the components removed from the installed forks instead of assuming either package contains the other seals or rings.

Match internal pieces by reference

The genuine Honda oil lock piece listing calls for comparison with the front fork diagram and OEM number. The spring set explicitly lists two springs with spacers and washers. Use the contents of the chosen product and the fitted assembly; avoid treating a spring set as a complete fork rebuild kit.

Common questions

Are the dust seals the same product as the fork seals?

They have separate listings in this selection. The dust seal product describes a pair for the DOHC application, while the fork seal set states its own dimensions. Compare the component and location you are replacing before ordering.

Does the stopper-ring pack include seals?

The stopper-ring product describes two metal rings above the fork seal, replacing reference 51447-KL4-951. It does not list seals as included. Fork seals and dust seals are separate products with their own package descriptions.

Does the fork spring set include spacers?

The spring listing describes two progressive-type front fork springs together with required spacers and washers. Read that listing against your fitted forks; its stated contents do not make it a package of all internal fork components.
