I know someone on this forum had one. I don't remember who, but there was a thread about the space under the seat where the alarm goes, and that person chimed in. That was the only time I have EVER heard of someone having one.
Here's the post I remember. It's on ADV. I think this is the only post I have ever seen someone mention actually having the alarm. http://advrider.com/index.php?threa...questions-thread.850525/page-68#post-22029528
My mate just installed one on his TR. I think he got his from a shop which had a leftover from a customer who never picked it up. The problem was he bought the alarm almost a year ago but had to take it to a BMW dealer to have it plugged into the MOSS to have the alarm hooked up to the ECU. It is apparently not just a plug and play. So if you don't have access to a BMW dealer who is willing to assist it may not work for you.
Seems like Hall's still has them: https://halls-cycles.stores.dealerspike.com/product.aspx?zpid=5509055 I also ordered an OEM bag from them and from what they told me, if it's on the website, they still have it...
Thanks for the replies, don't want to have it MOSS'ed for this install but thought it might be a good OEM item while they are still available.
