Graduate Cycle (ca 1977)

Rod's Suzuki 500
(anyone know the model number?)

The last time I rode a motorcycle I was a pharmacology graduate student at Temple University Medical School circa 1977. I owned a used Suzuki 500cc 2-stroke twin which I bought from a fellow grad student, Len Jacob.

I can't believe I never took riding lessons or read a book on motorcycling. I did have a helmet though. I commuted to grad school and my adjunct instructor job at Drexel University.
