I asked this at the show on Sunday.
The standard setting is damping (combined) if you want to separate the compression and rebound damping, you still need the 2D sensor, so I will be keeping mine
The new Marzocchi forks use a cartridge as other manufactureres do, the shims can be adjusted as any other shim stack.
The DDS is 'paralell' to the cartridge, this means it can be treated separately, whereas in the current '15-'18 models the DDS is in 'series', he also said that the current DDS uses minimum and adds whereas the new one uses maximum damping and subtracts dynamically, it therefore improves the response on the track and corrects the 'dead' feel that some complain about.
I got all this from Josef Maechler who is the S1000RR Product Manager for Euroope
I also asked about the 2D GPS lap trigger, this will also still be needed if you want automatic lap timing, I believe the existing one will fit, or we may need a different adapter cable, I have asked for clarification from BMW.
