I would only consider the Torino Terra 250 at a price of $3k on the road (USD since I live in the US and that is about the max price I would pay for a new Chinese bike), so I would agree with the others about a Japanese used bike, or the 650 Hyosung since you said yours reached 350, 000 km (or was it 35, 000 km which is still fantastic?). The one bike you did not mention, and would be one to consider if it is available in Australia, is the Qingqi GY200 which is available around the world under different brand names. This bike is relatively low cost and is as reliable as the Suzuki DR200 because Qingqi is the OEM for Suzuki's under 250cc engines. If you can find one at a price less than the Lifan 250 mentioned, I would consider it.

I am not sure if they are still in business, though...
