Between now and 1990, motorcycle emissions, if left uncontrolled, are expected to increase by over 100 percent. A large number of the regions in the United States presently exceeding the air quality standards for oxidants and carbon monoxide (CO) will continue to have difficulties in achieving or maintaining air quality standards in the 1980's. Uncontrolled emissions from motorcycles would add to this burden. When statutory standards for automobiles are met, uncontrolled CO emissions will be ten times as high and HC over twenty times as high for the motorcycle. Based on these predictions, EPA is preparing to propose emission standards for new motorcycles sold in the United States.
