I put BRP's rider backrest on my 2014. installation was unbelievably easy: four bolts to the seat pan, pop out the plug on top, and BOOM!

Initially: it wasn't set up for any rake adjustment. At SpyderFest 2016; I bought the upgraded bracket, and Brentc changed it over for me in the Hotel room...
...surrounded by the rest of us, who were trying to keep the "Barley-Pops" from getting warm! :cheers:
I liked it so much, that I pulled it off the bike when I traded it in. It'll be transplanted over to my 2018! :2thumbs:
