1981 Honda CB650C Custom Fork Oil & Dust Seals

Check the fitted forks before ordering seals for the 1981 CB650C. The oil seal set and dust seal pair serve different positions, and their package descriptions should stay separate. Do not extend another year’s retaining-ring application simply because its oil seals share a similar size.

1981 Honda CB650C Custom · Fork Oil & Dust Seals Buying guide

Compare both sealing positions on the actual forks

The oil seal set is specified at 35 × 48 × 10.5 / 11mm. The dust-seal product supplies two pieces. Identify the installed fork assembly and inspect any additional retaining hardware separately before preparing the service order.

Keep each sealing product distinct

The oil seal set and dust seal pair are separate choices. Inspect their positions and the existing retaining arrangement using the correct fork information. Package quantity for one type should not be treated as evidence of what comes with the other.

Check the fork’s history

A swapped fork can need different seals despite the motorcycle retaining a 1981 Custom frame. Identify that assembly and its dimensions before buying. Follow its correct service procedure for oil, installation and final checks instead of guessing from the bodywork or engine model.

Fork Oil & Dust Seals questions

Does 10.5/11 mm mean I can choose either seal height?

The listing gives the combined size 35 × 48 × 10.5/11 mm but does not explain the slash or describe alternative seals in the pack. Obtain a dimensioned specification before treating either figure as a selectable substitute for a different fork.

Are dust seals included with the oil seal set?

The dust-seal pair is a separate product. Inspect and choose it independently so the order reflects the condition of both sealing positions.

Can I use an earlier Custom retaining-ring listing?

Verify the actual year and fork arrangement first. Shared oil-seal dimensions do not establish that every retaining-ring application carries forward to the 1981 assembly.

Not sure which part you need?

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