Hi Spainy MY 2015 12rs suspension was also very loose comparing to my 2017 12rs.I took the 2015 to the bmw dealer and he tried the shocks by pulling the front brake in and pulling and pushing down on the handle bars with the ignition ON and i must say he did that a good few times before the bike activated the valve inside the shock to damp the movement.He then walked to the demo 2015 rs and did the same with that one with the same outcome.So i think it's more to do with the software than the shock itself.saying that my 2015 rs popped seals on 1000 km from new.When i got my 2017 12rs there was a notable difference in shock movement from sloppy to firm and stable.Hope you come right.
