The first street-legal motorcycle produced by Honda was the Honda Dream Type D, also known as the Honda Model D or Honda Dream 98. It was introduced in 1949 and marked Honda's entry into the motorcycle manufacturing industry. The Dream Type D was a small-displacement motorcycle with a 98cc four-stroke engine. It featured a simple design, reliable performance, and fuel efficiency, which made it popular among Japanese riders in the post-World War II era. The success of the Dream Type D laid the foundation for Honda's future growth as a motorcycle manufacturer and set the stage for the company's ongoing innovation and expansion in the industry.
