I think this quote from Aaron P. Frank's Honda Motorcycles sums up best why I like it:
"When Honda first appeared on the American scene in 1959, the company gained a reputation as the purveyors of odd-looking motorcycles. No doubt much of this impression was formed in response to Honda's early Dream (and Benly)- model motorcycles, which remain to this day some of the most distinctively styled motorcycles ever to roll off of a production line.
Drawn in the Jinja-Bukkaku style (which translates loosely to "shrine style", a reference to the angular architecture of Buddhist temples), the lines of the Dream are dominated by sharp creases. Everywhere that the Western eye is trained to expect curves, the Dream meets with edges. The rear shocks are rectangular in shape, as are the pressed-steel covers on the leading-link fork. The headlight is virtually square, as are the fenders, with acute creases along the radiuses. These design elements, coupled with the high "toaster" tank and the blockish profile of the parallel twin engine, give the Dream a quirky look that remains compelling even now, 40-plus years later..."
