Aprilia scooter servicing costs

Hi all, I'm looking at buying an Aprilia SR 125 GT Sport as it seems to be the best adventure style scooter I can get for the money but I'm wondering if anyone has any idea what the servicing costs might end up being?

Also considering a Voge SR1 ADV. I suspect the Aprilia's still the far better choice here but I think it really comes down to how much the parts and servicing might end up costing.

EDIT: Should probably add I'm not expecting a hugely specific figure, I'm just trying to figure out if Aprilias are any more or less expensive to have serviced than Japanese scooters.
