Topic: Will a '78 CB550 swingarm work on a '75 CB750?

[SDmtnbkr]

I searched my butt off but couldn't get a definite answer. I assume that any '69-'76 CB550 swingarm would work, as it's a known swap, but couldn't find any info on '77-'78 CB550 swingarms.

Any help would be greatly appreciated.

I believe this will bolt on. I think people do this swap because the 550 swing arm is longer than the 750.

the 77/78 K & earlier 550/500 K swingarms are exactly the same except that the grease nipple location changed and the pivot tube & bushes design changed slightly.

The 550s do have different swing arms but the frame spacing is the same. Some swing arms have different axle spacing and I believe the F models have closed axle ends.
