FYI: 1975 Hercules W2000 (rotary bike)
 

For the rotary enthusiast who has (almost) everything:

Worldwide Auctioneers - 1975 Hercules W2000 - The Burt Collection

That is sweet.

I remember the Suzuki Rotory bikes but not the Hercules.

Hmm, this auction is near me too.

There's a Hercules that shows up at DGRR most every year.
