Change the whole chainset to a new one before you leave - better to carry new sprockets and buy a new chain on route, but carry some master links. Chains can be bought in most places, but finding the correct sprockets can be difficult -especially on a newer bike like the 500x. Then put on old chainset when you get home.
If you have a good idea of where you will be when the chainset is worn out, ship a new chainset (and any other major service items) ahead and have them ready waiting for you to arrive - (or order some locally before hand) much better than carrying them, especially 2up. If you have to carry sprockets bolt them to the back of your panniers or to luggage rack or frame somewhere out of the way and make sure the teeth cannot injure you or your passenger if you dump the bike.
if its a 525 X or O ring DID you should get 25,000 - 30,000 kms out of it if you look after it.
Whats your route and expected total distance?
