As a young teen I was mesmerized by this film when it came out.  This film was to the 60's what "The Wild One" was to the 50's.  The definition of cool.  Now, decades later, I see much more in the film than I did back then.  The social issues.  Rebellion.  Drugs.  Freedom & travel.  Conformity & captivity. Love.  Hate.  Peace.  Violence.  The stars of the show remain the motorcycles (which  in this case, also served as vehicles of rebellion, escape, and non-conformity).
