I'm getting into building my '75 CB500t finally (same chassis for all intents as a CB450) and I'm looking for a beefier swing arm, something a bit more rigid than the floppy thing it currently has.
If that doesn't pan out I'll be welding on a loop brace...anyone done anything like that?

Lead, follow or get out of the way!

We made rectangular tube SA at Yetmans back in the sixties. Don't remember how many were made.

Sounds like what I'll need. Was hoping to wimp out and not weld one up myself......dosn't sound like that's gonna fly...

CB750f DOHC might work. At a glance it looks compatible but you will need to do your own homework. Also Suzuki GS1000 (I think, maybe GS750) are aluminum and even longer than CB750F - the CB750F guys use them as a swap.

Get out your measuring tape!

... and after some more research I don't think they will work - 9.5" wide at the mount versus 8" (CB450). Oh well, it was a nice thought.

Hmm....I'm not one to give up too easily.....I like the idea of an aluminum box section. I'm not above finding a viable donor piece and hacking and rewelding it. T'would be lovely to find something compatible directly but I'll not count in it.

I'll be running a set of Konis with adjustable damping and threaded spring jacks I am machining myself. Should be the bee's knees!
