David - I spoke to Kury by phone and in person at Daytona Biketoberfest, they do not have an adjustable passenger peg for 2017 CVO Limited. Did not sound like they had anything in the works either, which seems od considering how many of these are out there on older models.
On my 2010 CVO Ultra I used Kury #4505 Chrome Adjustable passenger pegs. Also come in black. My wife really liked these and Kury had nothing that would fit the 2017 unless you swap out the CVO boards & mounts for regular Ultra mounts - Harley or Kury. More than I wanted to spend to just get back to what I had on my 2010, plus had kept the Kury boards from the 2010. Decided to adapt these to fit the 2017.
Machined out the inside of the Kury clamshell to fit over the CVO mount. Friend has a milling machine, much better than a vise & a hand grinder. There was not enough "meat" inside that mount to get a flush fit. So far has worked ok & if the BSR is happy...you know the rest. The machining process was trial and thankfully, no error. Took a measurement, machined away material, took another measurement after fitment to determine how much more to remove.

Pic shows small gap in mount, final fitment.
There are other ways to get there, I did this because I already had the Kury parts & already had $200 invested. Good luck on whatever you decide.
