Custom Hardtail Kits and Hardtail frames for Sportsters and Shovelheads for sale at Throttle Addiction

Hardtail kits versus full custom frames

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.

Hardtail kits Made in the USA

Throttle Addiction offers weld-on hardtail kits for Harley-Davidson Sportsters, in addition to 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 come together as smooth as possible. All of our weld-on hardtails are made by Throttle Addiction at our facility in Eau Claire, WI.

 

Why do people hardtail their Sportsters?

Some people prefer to hardtail their motorcycles because it creates a distinct, classic look that is often associated with choppers. Hardtailing involves removing the rear suspension and replacing it with a rigid frame section, which can give the motorcycle a lower, more streamlined appearance. This can be particularly appealing to riders who want to customize their motorcycle to reflect their personal style.

Hardtailing a motorcycle can be a way to make it more unique and personalized. With a hardtail, riders can lower or raise the motorcycle to their preferred height, which can improve the overall look and feel of the bike. For those who enjoy customizing their motorcycle to reflect their personality and style, a hardtail can be a great option.

 

Why weld-on hardtails are better than bolt-on hardtails

A weld-on hardtail is better than a bolt-on hardtail because it provides a stronger and more durable connection between the frame and hardtail section. Welding creates a seamless connection, eliminating potential weak points or areas of stress that could arise with a bolt-on hardtail.

 A weld-on hardtail is also more customizable as it can be designed to fit the specific dimensions and shape of the motorcycle frame. Once welded, the hardtail becomes a permanent part of the motorcycle, eliminating the need for future replacements or maintenance required with a bolt-on hardtail. While a bolt-on hardtail may be easier to install, a weld-on hardtail provides a more secure, permanent solution for customizing a chopper.
