Fuel was extremely scarce and expensive, and by late 1949 some of Honda's competitors had turned to more economical [[four-stroke]] engines. Despite some initial reluctance, Mr. Honda decided to take the four-stroke path as well. This was an ambitious undertaking: If the company had to risk expensive retooling to produce such engines, the design would have to be a good one. But Mr. Honda was willing to wager everything on the strength of bold engineering ideas.

That design was an [[overhead-valve]] (OHV) four-stroke [[engine]], an idea far ahead of its time in [[:Category:Japanese motorcycles|Japanese motorcycle manufacturing]], where most were using lawn-mower-like flathead engines. An OHV engine allows higher rpm because it offers less restriction to airflow through the engine. Its more compact squish [[combustion chamber]] also allows a substantial boost in [[compression ratio]], giving not only more pulling power, but better fuel economy too. The single-cylinder 146cc E-type engine could go 220 miles on a gallon of fuel, yet delivered 5.5 horsepower, and in an impromptu test, a test rider took the two-speed prototype on a rainy ascent of the Hakone Mountains, while Mr. Honda followed in a car. The machine made the climb easily, in top gear, averaging 45 mph.

By 1952 demand for the Dream E was brisk, despite the existence of some 200 other motorbike producers. In fact, the E's sales success allowed the company to raise new money, which was used to renovate or build three manufacturing plants, as well as buy sophisticated machine tools and production equipment. It also enabled the company to cut its dependency on suppliers and set up its own distribution network. The Dream E design is regarded as the turning point in Honda's early history for all those reasons--and two more.
