Above almost all else, motorcycle frames shape the overall look and feel of your custom chopper. If you’re mulling over the idea of building your own custom chopper from scratch or from a custom bike kit, motorcycle frames are the piece around which you’ll want to build your design concept.
There are several styles of motorcycle frames to consider depending on the look you’re going for and how you’ll be using your custom chopper.
Measuring Custom Frames: When comparing custom frames, you’ll notice that they are described in terms of “stretch.” The amount of stretch in the downtubes refers to how much higher the custom frame is than the stock frame. The stretch in the backbone refers to how much longer the custom frame is than the stock model frame.
