Few quick questions, I can not find good information/guides on mopeds. When limited to 80km/h I didn't give way to anyone on the highway. Do I have to give way when I am limited to 50km/h? Who do I take my moped to get a compliance plate? Mechanic? What do I need to put on a bicycle frame to be compliant besides a 50cc motor? How much does it cost to get a compliance plate? Is there a way to make 50cc engine less noisy. I am in Newcastle, Australia.
