Thanks to Berkeley we have some photos of the new equipment installed on the Euro4 engine in the 2018 RS4-50 bikes.

This line looks like it come off the pipe, into a hose that passes through a check valve, and then goes into the air box. Probably to capture unburnt fuel.

There is a completely new CDI unit. Not sure what the extra connectors do yet. Hopefully a workshop manual for these new engines will pop up soon.

The pipe also has a lot going on with it.
