Low-Emissions Two-Strokes on the Market

Saving gas is certainly good for the environment but did you know many two-stroke scooters (old and new) emit more hydrocarbons than an average SUV? See Bajaj USA for their comparison on emissions.

Generally speaking four-stroke engines offer reduced emissions compared to two-stroke engines. More and more scooter manufacturers such as Honda, Vespa, Aprilia and Bajaj are using four-stroke engines to meet new 2006 EPA standards.

But two-stroke engines are still popular due to great fuel economy, increased power and cooler operation. As a result companies such as Piaggio (parent of Vespa) and Aprilia have turned to direct injection to meet emissions standards while still offering the benefits of a two-stroke.

The two-stroke 49cc Vespa ET2 can be seen at Vespa St. Louis and the Aprilia Scarabeo 50 Ditech is available through the Extreme Toy Store.
