The displacement of the four-stroke engines for motorcycles currently manufactured ranges from 50 cm 3 to 1.000 cm 3. Most of the engines for street use motorcycles develop approximately 1000 horsepower per liter. Four-stroke engines are utilized for such diversified purposes as street use, for sports riding, touring and business purposes, family use, leisure purposes including off-road use, motocross, trials, etc. Therefore, the emission control for motorcycles, for which appropriate engine configurations and performance are required, substantially differs from that for automobiles and poses many problems yet to be solved in the future. This paper presents the engine modifications that HONDA has developed on their 1978 model motorcycle four-stroke engines including measures to have been adopted to minimize deterioration and production deviations of emissions, and the resultant emission levels.
