Vintage Harley Davidson Big Twin Motorcycles are some of the most popular platforms for motorcycle customization. The undisputed king of Harley Big Twins is the mighty Knucklehead, but no one can argue the prominence of the Panhead and Shovelhead motors. At Throttle Addiction we carry the Knucklehead parts, Panhead parts, or Shovelhead parts to keep your vintage iron on the road. We have parts for choppers, restoration parts and maintenance items like oil and oil filters.
