Review
The backrest has good adjustability options.. up/down and back/forth.
Adjustability is not quick. It takes wrenching to adjust the position. If you have on a coat at the beginning of the ride and decide to take the coat off and find the backrest now needs an adjustment it is a time-consuming procedure.
The pad itself is too small - feels like a smooth fist against your back but support is adequate if you tighten it down good enough to keep it from moving as you press against it.
Found installation on the 2021 CanAm Spyder RTL to NOT be as smooth and easy as the instructions suggest - took some finagling to get the bracket mounted in the seat base.
Would not purchase again.
