I have an AN650 passenger backrest that I took off my Burg when I chopped it. It's in excellent shape. It's been sitting in a box getting dusty. Has all the bolts, screws and parts. There's a LED run/stop light mounted on the back panel. The cost is whatever a USPS flat rate box to your location costs.

In 36 days, when bike season starts for me this year, this is going into the recycle bin. I've been hanging onto it for way too long.
