No. They were also made for other Bikes, and other size Engines. Take a look at the Down Tubes, and the Motor Mounts. Mine was originally made for a 2 Cyl Engine. And a bigger Engine. My Down Tubes had to be cut and moved because the inside 2 Exhaust Ports of the CB750 Engine hit the Exhaust. The Motor Mounts also did not line up for the CB750 Engine. But if you really want an original Amen Savior Frame, especially a Plunger Frame like mine, you can make it work. Take some measurements, and see what you have to work with. I don’t Weld, but have both a friend and a Nephew who are Certified Welders. It all worked out for me. Good luck. “Make it fit”
