The Little Black Pig that Could
In the early 1920's, Harley-Davidson's racing team was unbeatable. Their 8-valve V-twins were no match for the other American makes.
One of the popular team members of the Wrecking Crew was Ray Weishaar. Ray had a pet pig that he paraded around the track after winning a race. Soon, the name "Hog" became associated with Harley as people shouted. "The Hog won again."
