Bugattz

Hi guys, Is there anyone who would be able to guide me in the case for a motorcycle. I have purchased the motorcycle from Vic and the seller said that it has 11months rego on it and with a custom number plate. He informed me that he would remove the number plate(custom) and transfer the rego to the new number plate and then send the motorbike. My question is whether do I have to pay for greenslip here and get it registered as I would do for a fresh rego for a second hand vehicle or do I have to pay only for the registration fee and stamp duty as I normally do when purchasing old vehicle with rego on it. Thanks in advance..
