Not got to that stage yet. Soon hopefully.
This is my theory and at this stage it's still just a theory. There are three wires that come from the speedo drive.
One goes directly to the speedo
One goes to the TPS and the Pick Up Coil
One goes off to the speedo and the Igniter Unit (ECU).
The Koso speedo I'm using also has three wires that go to the magnetic speedo pick up at the wheel. I would suggest as long as you splice in some wiring and maintain the feeds to the TPS, Pick Up Coil and Igniter Unit then you should avoid getting error codes. However if you use the speedo pick up that comes with your aftermarket speedo then the signals might not be the same as the OE speedo sensor on the wheel. I don't know how you would check that, but someone with good electronics understanding would probably be able to work it out. If you are using the OE wheel then you could use the OE speedo sensor to drive your aftermarket speedo. On the Koso you calibrate the speedo so it knows how many pick up points it's looking for and I'd assume other makes work the same. Just to reiterate, this is all still just theory on my part and I hope it makes sense.
One thing does bug me though. For those owners that have had their bikes set up on a dyno, did they get error codes? Because the front wheel wouldn't be registering any speed.

Feel the Fear and do it anyway!
