    I need some more swingarm dimensions!

    Anyone still around that remembers this?



    I'm doing more of that shit again! I'm working on a 2002 Honda Shadow 750 (see it here) and my original plan was a Yamaha R1 rear wheel. Getting it to line up has been a little more cumbersome than I had hoped. Just for kicks I'm not looking at a single side swingarm setup...but here's the rub...

    My previous projects (the TL1000S and GSXR1000) the spread in the swingarm up front didn't matter and there was very little issue with the arm's offset. This project might not be the same with the offset, but the spread up front is definitely important as the pivot bolt goes through the frame AND the motor. I need two things:

    1. Offset: how far to the left does the swingarm extend past the pivot? How far behind the pivot does it go before it starts offsetting to the left?

    2. I have the overall width of the swingarm at the pivot, but what is the inside width?

    Somewhere around here there's some CAD drawings that May answer your question and be a visible cue as well. Take a gander for the CAD drawing threads. Maybe ParcNHawk or another one of the members who hangs out here more frequently than I've been here lately can point the direction if they know the location of such?

      FYI even at its under sprung weight of approximately 1100 lb spring on the stock shock ( usually more spring weight ) is required and desirable. This makes the frame attachment point critical for structural rigidity. A spaghetti tube frame may need some substantial modifications or beefing up to handle the non linkage damper setup.

        See if any of these files can help you out?
        I know we have at least two versions of the frame, and there's another member here who would like to share their drawings as well. We will be keeping this thread as a sticky. So with that being said, wildwhl and frinesi2 , feel free to add your files for posterity. Here's a quick reference of parts in this thread: Post #6 -


        IDK Maybe you just want someone with a tape measure to go out to the garage?

        Happy Hunting !

            If you really want to blow your mind check bogan 's custom one off linkage drawings for the Hawk swingarm/frame there should be an entire thread on that somewhere lol

              Anyone know if a '96 VFR750 eccentric would fit in the GT's arm?

              It looks like the Hawk arm will work with my project, and there's a local VFR750 I can get pretty inexpensively that has the full rolling assembly.

                  yeah some of those hits say you have to use the hawk eccentric and some say either or. Plus, early 90's 750's and mid 90's 750's aren't entirely interchangeable. That's why I'm trying to confirm it.

                    If the eccentric is the same between the 96 VFR and the 650 then it's a done deal

                        I didnt think about it until this thread popped again but there is a 3d model of the swingarm you can download and windows 10 has a built in app for looking at those models. You can also download a free version of fusion 360 and use that to get dimensions based off the cad models. Might provide usueful.
