O Shit Look what we Did!!

Nice, but I think the I-beam design is not yet fully developed,
have a look at e.g. VOR or old KLX250 swingarms:

Both swingarms are drop forged and welded (KLX) resp. bolted (VOR) together....

the swinger looks great! I don't think it would work on a 450 Lingo. I'm not certain about that though, but I don't think a 750 and a 450 swingarm are interchangeable.

Guys, you could think about doing one for a 360, so you would cover the 350,360 and cb450 with one design! The axle bolt is the only thing different and a 17mm for the 360 is the size, so for a 450 only a hub is different.

Next question, will it fit my cb450?

+1 would you guys consider them for other hondas?

Grant it look purdy but i have some doubts about its rigidity in the lateral plane compared to say a conventional box section swingarm. I beams have very different characteristics than Box sections. It looks like it would be stiff at the front, but you need the FEA first of both designs and then you should deflection test on a rig and test for deflection and strain.

See DR Rob Tuluie's Tularis story for details.

BTW, I suspect I need to be sitting down with a strong sedative available when you tell us the price ;-)

I agree with what your saying teazer. That is why we are doing some FEA test and deflection test. We have access to a computer program that will model the part and put several different forces to the part. We plan to do computer test until failure of the swing arm. We will then do some real world testing. (Have not decided who that person is going to be though). We already know that the swing arm bolt junction is going to be much better than stock. But until we get this on a bike and run some test it remains to be seen. Like I said in my email we have made some revisions already. Much less expensive to make changes on the computer than the actual part. Time will tell but I think we are going to be very successful in our design.


You may want a horse tranquilizer when I tell you the price, chase that with a shot of whiskey too

I work at an automation company, and we use that COSMOSXpress tool that's part of SolidWorks to virtually stress test most of our parts before manufacturing them. It works pretty well. We relied on it heavily when we designed a robotic end of arm tool that was carrying two 30 pound brake rotors for a pickup truck at 2 meters a second. You could do pull ups on that tool and it still came in under payload.

As long as the price doesn't exceed what I paid for the original bike, I probably won't faint or anything.
