1973 Honda CB350F0 · Seat Hardware Buying guide

Inspect the latch before replacing seat hardware

The lock bar is a mechanical service part for the seat’s retaining arrangement. Check the surrounding mounts and engagement points as well, particularly when the seat pan or upholstery has been changed.

Parts to consider

Match the lock-bar assembly

The replacement assembly corresponds to the two listed Honda lock-bar references. Compare the existing mechanism and its mounting before ordering. Damage elsewhere in the seat’s retaining arrangement can prevent correct engagement even when the lock bar itself is serviceable.

Check modified seats carefully

A replacement seat pan or changed mounting position can alter the latch alignment. Inspect how the seat meets the frame and retaining mechanism before buying original-type hardware. Keep upholstery work and latch repair as separate decisions so each problem is addressed by the appropriate part.

Seat Hardware questions

Will this fit a custom seat pan?

Compare the custom pan’s retaining arrangement with the original-style lock bar first. The model application does not establish fitment to a modified latch or relocated mounting point.

Does a new lock bar fix a misaligned seat?

Check the seat mounts and the matching engagement point before ordering. The assembly replaces the lock bar; correct alignment still depends on the condition and position of the surrounding seat and frame fittings.

Which original references does it replace?

The assembly is listed for references 77220-340-003 and 77220-340-011. Compare the removed component and its mounting arrangement, especially if the motorcycle has accumulated replacement seat hardware over the years.
