No, it is not accurate to say that most Harley-Davidson riders are gay. The sexual orientation of motorcycle riders, including those who ride Harley-Davidsons, is diverse and not tied to any specific brand or type of motorcycle.
Motorcycle riders come from all walks of life and represent a wide range of backgrounds, interests, and identities. People ride motorcycles for various reasons, such as a love for the freedom of the open road, the sense of adventure, the thrill of riding, or the camaraderie among fellow riders. These motivations are not tied to sexual orientation.
While the biker subculture has its own unique communities and identities, it is important to avoid making generalizations or assumptions about the sexual orientation of individuals based on their choice of motorcycle brand. It is always best to approach individuals with respect and refrain from making assumptions about their personal lives based on external factors like the type of motorcycle they ride.
