No definately not, but I am a dreamer and proud of it. Following is the 1985 spec sheet for Maico models, including their water cooled 530cc 71hp Chair.
I believe a guy called Zabel, was actually a sidecar team mechanic/racer.
When the factory spoils got liquidated in 87, Zabel kept the maico big bore dream alive and eventually these monster horse power two smokers came to bear his name of course.
I think Vince down your way has a couple under the bench, that he wanted $1,500 for both.
