What is the difference between a weld-on hardtail and a full frame?

A weld-on hardtail attaches to the front section of your stock Harley-Davidson frame. A full frame is a complete, one-piece replacement that comes with a new vehicle title (MSO) for registration.

Can I install a weld-on hardtail myself?

Yes, with caveats. Weld-on hardtails are designed for installation by skilled and experienced fabricators. We strongly advise that only individuals with appropriate welding and fabrication knowledge and expertise undertake the installation. When in doubt, you can do the preparation and fitting of the hardtail yourself, and take it to a professional welder to have the finish welding completed.

Do I need a new title if I use a full replacement frame?

Yes, all of our complete sportster chopper frame options are sold with a Manufacturer's Statement of Origin (MSO), which you will use to register your new custom motorcycle with your local authorities.

Harley Sportster Frames & Chopper Chassis

The Harley-Davidson Sportster is the ultimate platform for a custom build, and the sportster frame is its backbone. Whether you're converting your stock bike with a weld-on hardtail or building a ground-up chopper, we have the high-quality harley davidson bike frame components to create the perfect stance.

Choosing the Right Sportster Frame for Your Build

The frame you choose dictates the entire look and feel of your motorcycle. Here’s what you need to consider:

Weld-On Hardtail vs. Full Frame: A weld-on hardtail section is the most popular way to get that classic rigid look by modifying your stock harley sportster frame. A full sportster chopper frame is a complete replacement, offering custom geometry like stretch and rake right out of the box.
Know Your Model Year: Sportster frames changed significantly over the years. It's crucial to select the correct frame or hardtail for your specific model, whether it’s an Ironhead, a 4-speed Evo, or a 5-speed sportster 1200 frame.
Rigid Ride vs. Swingarm: A rigid frame or hardtail provides the cleanest, most traditional chopper look. While some search for a sportster swingarm frame, the classic custom path is a rigid frame, which sometimes requires a sprung motorcycle solo seat for comfort.
Complete the Build: Changing your frame's backend requires other parts. You'll need to consider a new motorcycle oil tank, fender, and mounting hardware to complete your custom sportster frame conversion.
