I am with TitanRanger, if it works for the 2013 It should work for the 2014. That being said here is another option, it is the link to the adapter plate for the Shad topcases. Get the plate then buy the topcase you want. I do not know anything about the product except that they are out there.Firstly, let me qualify my following statement: I have NO previous experience with Givi products, but I understand that they make a nice topcase. Givi makes topcases and mounting brackets for the 2013 R12RT's (and prior). A BMW topcase for a 2013 R12RT will fit a 2014 R12RT...if that is the case then a Givi mounting bracket for a 2013 12RT should fit a 2014 12RT. Is my logic flawed?
I use the Givi Trekker 52 L top case with their rack and backrest when I use one. If I remember from the application chart, the mounting adapter plate for my 2009 was kind of "universal" and left quite a bit of latitude on how it fit.I'm not sure, but I'm thinking the Givi adapter plate for the 14s may be, MAY be, different than those from previous years. TRanger's logic should be sound, but the overall shape of the 14 rack may be slightly different than the previous years. The mounting holes may be the same, but the overall shape may not and that may necessitate a different plate.
