1970 Honda CB100K0 · Seat Supports Buying guide

Plan the order around the seat underneath

A seat cover’s appearance tells you little about its support rubbers. Inspect the pan and retaining positions, then use reference 77205-286-000 to identify the B-type cushion described here.

Parts to consider

Honda CB Seat Rubber B ~ Replaces 77205-286-000 Seat setting rubber BSeat-to-frame cushion replacing reference 77205-286-000. Sold individually for CB100K models from 1970–72.View part

Choose for the support position

Seat rubber B is offered as a replacement for 77205-286-000, for CB100K models from 1970–72. Match the cushion’s shape and attachment to the position on your seat. Do not assume every rubber underneath a seat is the same type.

Order around the pan you actually have

An aftermarket or repaired seat pan can change the mounting arrangement even when its cover looks appropriate. Compare its underside before buying and identify missing supports separately from damaged hardware. The individual supply format lets you order the confirmed B-type quantity without assuming a complete kit.

Buying questions

Will a replacement seat cover change which rubber I need?

The support choice depends on the pan and its attachment points, not the cover material. If only the upholstery changed, inspect the existing supports; if the whole seat changed, verify the underside before selecting rubber B.

How do I calculate an order for missing B-type seat supports?

This cushion is sold individually. Identify the B-type positions on the actual pan before counting the order quantity; where supports are missing entirely, confirm their type from the pan details rather than assuming every location uses the same rubber.

What should I compare if the original rubber has disappeared?

Identify the retaining features and contact position underneath the seat, and use reference 77205-286-000 when asking for confirmation. A photograph of that area is more useful than the seat cover’s color or pattern.

Not sure which part you need?

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