Ten motorcycles were tested at a time according to the requirements of the ECE-regulations 40 and 47 with regards to their exhaust gas emissions. Beside the gaseous emissions CO, CH and NO/sub x/ the particulate bounded PAH were measured. Additional the gaseous emissions at constant speed were investigated, more over the influence of different variations to the exhaust gas emissions. The measurements showed, that the emissions of modern motorcycles are in most cases lower than the limits. The determination of the PAH proved higher emissions of carcinogenic PAH-components from the two stroke engines than from four stroke engines. The determination of the exhaust gas components at constant speeds showed for the ECE-regulation 47 motorcycles at maximum speed due to the decrease of air-fuel-ratio the tendency for a great increase of CO-emission and a less distinct increase of HC-emission. The determination of the exhaust gas components at the variations showed a strong interdepencence of the exhaust gas emissions from the choice of the gearshifting points and the adjustment of idle-CO.
