Hi all; I'm considering a contract that would keep me in Australia for six months to a year. I am looking at motorcycles (new and/or used) to get for the duration of my stay there, and I have some questions: 1) What exactly defines a "learner bike"? Engine power, engine vs. mass, something else? What is the number? Is it the same for all federal units? 2) I notice Australia seems to be one of the few countries where the engine power (in hp or kilowatts) is not advertised. Is this item stated in the motor vehicle registration slip, just like make/model, gross mass, colour and the like? If not, how can one find out what is the engine power of a bike sold in Australia, where internationally the bike is available in two different versions, for instance one with 35 and another with 45 kilowatts? 3) What is generally required if a motorcycle purchased and registered in one State is sold privately in another? All answers and comments are much appreciated.
