Handguards and risers WITH Wunderlich Handllebars

[inditx]

I have a 2016 R1200RS with the Wunderlich handlebar conversion and didn't need any cable extensions.
I would like the bars a bit back and up just a titch yet still.

What risers would work?
Would I then need to add cable extensions?
What handguards could I add?

Thanks in advance
