There are two basic styles of passenger armrests for the Honda Goldwings: drop-down and swing-out.
The armrests of the drop-down style literally drop down over the saddlebag lid. These armrests are installed with a hinge and bolt system positioned close to the trunk mount bar above the saddlebag. Drop-downs may make mounting difficult for some passengers. These armrests may be impaired by rails installed on the saddlebag lid.
The mounting weldment of swing-out armrests are installed underneath the trunk on the mount frame. The weldment attaches to trunk mount frame with u-bolts, washers and lock nuts as shown below.
This picture illustrates a complete swing-out armrests installation on a 1983 GL1100 Aspencade before the trunk is put back on.
Swing-outs swing wide and clear of the saddlebags making it easier for passengers to mount and swing clear of any rails installed on the saddlebags.
