i can see no reason why you need do more than a simple repair.
If it were me I'd 100% just repair these. The only gotcha it to make sure you still have enough length.
The easiest might be to buy a cabled connector stub, and splice it in, rather than try to crimp a new connector to the end of the current cable.
Maybe give yourself a few extra inches of cable on the repair to allow for the soldered joint being a little stuff.
I've had luck buying ebay or amazon "bullet-connector to ducati turn-signal connectors" and just cutting off the end I needed.
Something like
this but for whichever connector you actually need (these are turn signal connectors).
