They look like battery cables to me.Not coils.
Earth strap from battery and positive to stater motor possibly?
If you don't have these already, then "maybe". But I doubt it. Not large enough to carry the current required for these tasks.

I stopped at the local shop today and there happened to be a bike like mine belonging to a customer. I was able to have a look. Apparently, one of the wires goes behind the voltage regulator mount bolt. the other end goes up where I couldn't see it.
For that one I'd mount the other end to one of the timing cover screws to have a good ground.
