1983 Honda CB1100F · Fork Seals Buying guide

Seals and dust seals together

Dust seals keep grit away from the oil seals, so worn dust seals shorten seal life. Replacing both together during a fork rebuild keeps the job tidy.

Installing the seals

A 39mm split fork seal driver in carbon steel is listed under fork suspension tools for the CB1100F. A driver helps seat seals squarely without damaging them. Follow your service manual for fork disassembly and oil quantity.

Mis-tagged items

This category also shows a front reflector, which is only offered in Canada, and a 16mm clutch and oil filter rotor lock nut. Neither is a fork part, so they are not featured in this guide.

Fork seal questions

What size are the fork seals?

The fork seal set lists 39 x 52 x 11mm and names the 1981-85 CB1100F, CB1000C, CB900F and CB650SC. It is made in Japan by an OEM supplier.

How many dust seals come in the set?

The fork dust seal set contains two seals, enough for both fork legs. The listing describes them as made in Japan and lists the 1983 CB1100F.

Is fork oil included?

Neither listing mentions fork oil. Check your service manual for the oil type and quantity, and buy the oil separately before you start the rebuild.
