For $700 difference in list price, what does one get for that additional money in a Ruby over an ES, especially now with all the changes made to the ES? It's only about 25cc's bigger, and has the Hondamatic transmission. Both models are about the same overall dimensions. The Ruby is liquid cooled and has front disc brakes. I'm not sure about gas tank sizes. Is the transmission itself worth the extra dollars? Are there other features that make it worth it I'm not seeing?
