Abstract
Due to low first cost and economy in running and maintenance, two wheeled vehicles, that is, scooters are becoming very popular for urban transport in developing countries, particularly where the year-round climate is moderate. The present study was carried out at Roorkee in India as a theoretical investigation of the dynamic characteristics of the prototype of an indigenous scooter, RAJDOOT, which is being developed by Escorts Ltd. The results are compared with the existing data for the Italian scooter VESPA.
