These are Honda Dream 300s. The designation
is CA77 and the motor size is actually 305cc.
They came in red, white, blue and black. The
black one is a 1966, the white one is a 1964
and the red one is a 1967. I under stand that
these were made until 1966 and the unsold ones
were titled in the year they sold.
A close look reveals a pressed
sheet steel frame and fender combo, forks (with
leading link springer hidden inside), head light
nacelle and side covers. Not much tube steel
here. Square is the predominant shape and sharp
lines rule. Very distinctive bike that gets
lots of attention everywhere it goes.
