What animal is the Harley Davidson motorcycle often referred to as?

For nearly 100 years, Harley-Davidson motorcycles have been referred to as "hogs." Although you may assume that this nickname has something to do with the size or sound of their motorcycles, the true origins of the nickname are rooted in racing. In the years leading up to World War I, Harley riders dominated the sport of motorcycle racing. The Harley-Davidson racing team acquired a pet piglet, which was quickly adopted as the team's mascot. A tradition soon began of riding a victory lap after each win with the pig, whose name was Johnny. It is because of "Johnny the Pig" that Harley-Davidson motorcycles are called "hogs."
