One of the best ways to turn your stock motorcycle into a chopper is to hardtail the frame. There are many advantages to using a hardtail on your stock frame. The most notable advantage is the avoidance of a special construction title which comes when building a chopper using a full custom aftermarket frame. Throttle Addiction offers weld-on hardtail kits for Harley Sportster and Big Twin Shovelhead and Panhead frames. Our hardtail kits can be purchased in deluxe form which includes a sissy bar, fender and oil tank, or individually. We offer specific parts that go with each kit so your chopper project can go together as smooth as possible. All of our weld on hardtails are made by Throttle Addiction in our facility in Eau Claire, WI.
