The 2020 RT's have completely different seats to the earlier RT's, so while your 2016 RT Rider's backrest will fit any similar std RT Seat from 2010 right thru to 2019 (with the appropriate 'under-seat' bracket of course!

) I don't believe that it'll fit on the 2020 RT's at all! :shocked:
Sorry, but if you've gone & bought yourself a new 2020 RT, then it's probably also time to buy yourself a new backrest! Enjoy!
