I had a 2011 Kawasaki Concours 14 but compatible with all model years between '08 and '22.
THIS IS ONLY COMPATIBLE WITH THE AFOREMENTIONED MODEL YEARS.
Works great in stabilizing the Concours for rear wheel work or in conjunction with a front wheel lift. (Protip: extremely easy to engage if the bike is on its center stand first.)
The product website pretty much tells you everything you need to know:
The Concours Rear Stand should fit '08-'22 Kawasaki Concours models. It was developed with feedback from C14 owners, and features height adjustability so that you can fine tune the height to your needs.
Also including an unopened set of EBC brake pads. Not sure why I have them but verified they're compatible with a 2011 Connie.
