This research quantifies the real-world emissions and fuel economy of a BS-VI motorcycle. The emissions estimation by standard driving cycles in the laboratory does not represent the emissions factors estimated in real-world driving experience on road. In real-world driving conditions, the emissions of motorcycles were influenced by vehicle driving patterns and traffic conditions. The time-speed data was collected during peak and non-peak hours on weekdays and weekends. The fuel economy and emissions factors were estimated for peak and non-peak hours by simulating the time-speed data on a chassis dynamometer interfaced with a gravimetric fuel consumption meter and a 5-gas analyzer. The average and maximum speeds of 29 km/h and 60 km/h in urban, 33 km/h and 72 km/h in rural, and 47 km/h and 79 km/h on highways respectively were observed. The CO and HC emissions were higher during peak hours on weekdays in urban traffic conditions compared to other traffic conditions.
