I recently traded in my 2007 RT for a 2012 RT. I had a set of K1200RS mirrors on my '07 which I habitually used since I first added them back in '08. On the way home with the new bike, i suddenly noticed that I was somewhat blind to the rear so have been searching for additional mirrors. When I get ready to tour and camp, my gear will essentially block all rear view from the stock mirrors.

I found mirrors and an adapter at A&S for $213.00 http://www.ascycles.com/detail.aspx?ID=76241

I also found what appears to be the same thing on ebay for about $123.00:

Anyone here added auxiliary mirrors to the newer RT? I think if I could just buy the little mounting adapter, then I could have a choice of mirrors in the future. Advice, please!
