This is the TOURTECH windscreen accessory mount that is no longer available from Touratech. They sold it as a GPA mount. However I advise against anything with weight being attached to it as the windscreen bracket can not handle the vibration and can break at the welds. I switched to the handlebar mount version. This should be fine for lighter items. This free, but you must pay shipping. you can call me at 713 664 7332 if you are interested.
Thanks
