You have got a great bike over there
What some mentioned already this is a 1968-1971 version,
But we need more info, serial number, number on cilinder..
By the way, most A-tank are in chrome, but I know in France was it possible to have one in your color, but was not common.
I’m not the biggest specialist, I’m a junior in comparing with some seniors here. But I have got a RS from 1969.
What I can tell you, it drives really good, fast and reliable, in short terms it’s a dream of a moped.
Asking price?? No idea of the Australian market, I know it’s a little bit higher than in Belgium. $2900 should be possible ( in this state ) wish you a lot of succes and if you have question, please feel free to contact us.
