Hey, new here im 22 and on my green P's and planning to go on my first adventure! Here's the Plan: pack light as possible, Sydney to Adelaide via broken hill then back home via melboure & saphire coast in 10 days. Going solo, camping mostly, might do 2 up for 20% - 30% with girlfriend. the issue I have is I have 2 bikes, a 82 cb400n rat bike or a 94 dr650. It's going to be allot of highway. Is there a way to make the dr aceptible for highway 2 up? Will the cb be semi decent off road with on/off tyres? What would you choose? Why?
