1973 Honda CB175K7 · Seat Support & Lock Bar Buying guide

Inspect support points and latch hardware separately

A cushion supports the seat against the frame, while a lock bar belongs to its retaining arrangement. Check both against the fitted seat pan, especially on a restored or modified motorcycle.

Build a position-by-position cushion list

The B-type seat rubber replaces 77205-286-000 and is sold individually. Inspect each matching seat-to-frame support, then order only the missing or deteriorated cushions. Where the pan has been replaced, use its actual cushion mounts and contact positions to plan the repair.

Match the locking arrangement

The seat lock bar replaces 77220-340-003 and 77220-340-011, with an explicit 1972–73 CB175K application. Compare the fitted bar and retaining arrangement. If the repair also needs a key or cylinder, establish those components separately before choosing the order.

Questions before buying

How many B-type seat cushions should I buy?

Each purchase supplies one cushion, replacing 77205-286-000. Count the matching support positions needing renewal under the fitted seat; no complete-bike cushion quantity is specified for this product.

Does the lock bar include a key and lock cylinder?

The documented product is a seat lock bar assembly; a key or cylinder is not named. If those pieces are needed, confirm them separately before treating this as a complete lock replacement.

Will these parts fit a custom seat pan?

Compare the cushion mounts and lock-bar arrangement on the custom pan first. The standard model application does not prove that replacement bodywork retains the original mounting and latch geometry.

Not sure which part you need?

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