This study aims to suggest ways to encourage electric motorcycle dissemination based on the factors that influence electric motorcycle purchasing decisions and the Importance-Satisfaction Analysis. To achieve this, 121 electric motorcycle riders were surveyed. Regression analysis and Importance-Satisfaction Analysis were used to derive variables which affect the satisfaction of electric motorcycle riders and identify priorities for major improvements. Conducting regression analysis showed that the factors that positively affect the use of electric motorcycles are "design" and "charging cost" while those that negatively affect the use of electric motorcycles are "distance/charging", "charging time", "charging method", and "maximum speed". These four factors, which adversely affect satisfaction, emerged as the main items for improvement in Importance-Satisfaction Analyses, suggesting technical performance improvements related to these factors and improved infrastructure would encourage the use of electric motorcycles.
