You can put a digital Speedo or a combo Speedo/Tach in the tank console.

There is no need for a speedometer cable with a digital speedo option. You have the option of using your stock cable of course. Or you can swap out the cable for a magnetic bolt. Which is just a wire (No cable).

I'm not sure what Martin62 mean by saying that the gauge needs to be tilted forward.

Mine is just set in it's whole with no bezel tilting it forward.

This is what I have.
