In order to get more riding time I built some arm rests for my Swing, so the wife could come along. The materials are inexpensive, and easy to get. The arm rests mount to the Givi Top Box mounting plate. The brackets, and hinge are made from 3/16" x 2" flat stock. The arm rest is made from 3/8" steel rod, 1" x 1/8" flat stock, and the pads were from a discarded office chair. I drilled one hole in the Givi mounting plate. The brackets fit right up against the bend in the Givi plate. The arm rests swivel in and out while not interfering with the Top Box. The hinge maintains tension by using a nylon locking nut. I attached a cup holder to the right side arm rest. Caution... the welds are not pretty, but they hold well. The pictures are in my album.
