The bike in picture #1 was built using these components. It converts the'78-82 Honda CX500 into a monoshocked cafe, or bobber, depending on which direction you go. It is almost completely bolt on, except for the lower shock mount.
That could be bolted on as well, but I recommend welding it. This is a "builders" kit that requires a little bit of mechanical inclination. Although, you could easily adapt a cafe seat on it. Until I can get the updated kit finished, I will be happy to walk someone through the mounting process if needed. Feel free to ask questions.
