No, not all parts of Harley-Davidson motorcycles are made in China. Harley-Davidson sources components and parts from various suppliers around the world, including countries like the United States, Mexico, and other locations. Like many global manufacturers, Harley-Davidson has a global supply chain and may utilize parts from different countries based on factors such as cost, quality, availability, and expertise. It's important to note that manufacturing and sourcing decisions can change over time, so for the most accurate and up-to-date information, it's best to consult Harley-Davidson or refer to their official communications regarding their supply chain and manufacturing practices.
