I wonder since you have the original key, would it be possible to find a locksmith to make a barrel chamber, with the necessary pins and tumblers, from the profile of your key? That would mechanically repair things.

The bike does need its matching chipped key fob, immobiliser key fob pick up at the barrel and ECU to electronically complete the ignition, all of which you still have, I guess.
