Frames / Rolling Chassis
Demon’s Cycle specializes in frames and rolling chassis for Harley and Harley style engines. We offer a great selection of quality custom frames in rigid, softail, bobber and pro-street styles. Width of our frames varies from stock to 330 wide. We accommodate Big Twin motors and Harley Sportster engines.
If you are looking to build a fully custom motorcycle, Demon’s rolling chassis is a great way to start the project right. Select your frame style: Bobber, chopper, prostreet, softail or rigid and then select the style of rims and front end of the rolling chassis. We have many great choices of rolling chassis starting at very basic and going all the way to a very fancy chopper. You can see some examples of motorcycles built on Demon’s rolling chassis in the ads and in our gallery.
