Original Schwinn Marman twin engine motorbike

[Reddindian]

I just made a deal on this very rare Marman twin engine motorbike that uses the Schwinn frame. These were only made for 2 years and these engines were originally used by the U.S. Air Force. It comes complete with everything some stuff not shown but I have it plus extra. Very Kool piece of History here. I am glad to own.

I'm guessing Schwinn just made one style motorbike frame ( WZ cantaliver & DX ) for Whizzer and others so do the belt dimples in the frame just line up for different motors belts?

She built the engines.

The schwinn MP-97 was specially made for this purpose for marman. Which mine is.

So @Reddindian maybe you can clear this up for me. The ad for a MP97clearly shows a cantilever frame and you show a cantilever frame bike at the bottom of your post but the bike the engine is mounted on is a DX frame? What gives? V/r Shawn
