    this is why the cafe racer trend and most of the people who "build" them suck.

    I do not have a problem with removing the rear part of the frame if you can justify it. Which is obvious since I did that to my bike (which I believe Raven was somewhat critical of in another thread). But I agree that the running the top frame tubes into that piece of angle is dumbfounding. There's a whole bunch of ways that could have been done better. And what gets me is that it does not even seem like they are using that space for anything. Maybe that is where the toolkit will go....

    The other thing I think is funny is that it looks like they added as much material on as they cut off. If you are not shedding weight it seems like you are missing the point of removing pieces of the frame.

    I just realized there were more pages to that thread. Have you guys read through all of them? Did you see the rearset mounting! This is my favorite part:

    "We also had a change of plans on the rear set mounts. We made up some brackets using these templates, but they were just WAY too thin. Even doubled up, they flexed and bent."
    "So we made some plates out of MUCH thicker metal and welded them on."

    And the final product...

    All i know is that carpy's father invented the cafe racer in the 50s using cb750s in CA, and thats how he did it.
    Latter his cousin benjie found a old storage locker filled with traditional hoops, since then everyone building a custom motorcycle turns to these parts.
    I also watched a TV show that has experts on how to build a cafe racer. They hacked the whole back off a CB750 and said that as long as the wheels line up its really easy to replace the frame....

    Problem that I have is that there are ways to do this right.
    I dont mind the rear hoop thing to clean up the back and mate it with the seat. Fine, but putting the battery up there?
    The problem comes with this idea that everything should be done for zero money and with what ever you can find on the floor.
    So thats where stupid metal choices come into play and poor welding.

    I saw those....[:0] Unfortunately there isnt much you can do if he is truly having the ergonomic problems he described. If I find and build one, its gonna be midcontrols and dirtbike bars.

    Why oh why didn't they drill and tap the plates?


    I would have run the tubes all the way to the spine. Of course I would have also turned little inserts and pressed into the tubes as alignment/strengthening aids and made liberal use of gusseting on the outside of the tubes. There is a tube butt joint in there someplace just waiting to surface. The angle iron continues to baffle. Its setup like a little L shaped spring in the frame. Gives new meaning to the old saying "hinged in the middle" eh?
