My brother had a copy chinese Chang Ziang 750 as a solo but with the chair brackets.
It had the leading link front and useless drum brakes, compression, what little it had, was the main barking force. Not suited to modern traffic in anyway. It also had reverse gear and a hand lever change, very weird compared to my usual rides.
Was a laugh to ride but only for gentle jaunts in the country.
However, I would not kick it out of the collection if free and on clasic rego.
Today, I went to get a green slip on the bike and its $882- a bullshit amount.
