They have a novelty value and are seen as
"Real" Harleys by their fans, later EVO motors
are much nicer and easier to live with unless
you like holding spanners and not handlebars.
They are from an era when to be a rider you had
to be a mechanic. Not like many of the "wanna be"
owners that play at being weekend outlaws today
with their dealer serviced turn key and ignor bikes.
I'd buy one if it was real cheap.
Don't compare them to a jap bike,
