Topic: longer swingarm for cb550

[unkle fester]

what swingarm that is longer will work the best for a cb550??....I like the look of this bike but that's not the stock swingarm on it......any suggestions???........thanks

  You did know that's a 400 in that pic right?  Could be a later 550 swingarm.

[unkle fester]

yeah....knew that....I want to do a 550 similar to that though......by looking at the shock angles, I'll need a little longer swingarm on the 550.........

You looking for straight bolt on or something you could modify?

Because you could technically modify anything to fit the length you are looking for.

Maybe a later 750 swing with some trimming??

   Just a hint, YZF600R swingarms are about 2-3 inches longer and VERY close width wise at the pivot.

i had a 750 parts bike and was gonna try its swing arm for my 550, but theyre the same length too.

I lengthened one for my 750. I cut the middle of the flat area behind the bearing area. Then inserted 1 1/4 angle into the swing arm legs, mig welded that into the legs and to the front section. i left a gap equal to the stretch I wanted and tig welded plate over the gap. the edges are a bit of a challenge to get looking right so I boxed it square and welded it up. One saturday morning. CLEAN off the paint before welding it is nasty if you burn it and will make you sick. I was able to leave the brake bracket and slice the weld from the front part and re weld to the new plate.

Have you looked at a '80-'82 cb650 swingarm?
I used one of those to get a longer swingarm than the stock '79 cb650 uses.
Not a straight across swap, but it works well with a set of custom bushings.

1982 cb1100f, you'd have to make some spacers though

hey fester, I dont get on here much but wiseguy did one for my 550. I also donated a 750 to set up a jig for him, you might give him a yell. Ive also got a 500 ninja, but cant remember how it measured , it did fit between bosses. ld part with it ya need it shoot me a pm. Ive got 28 bucks in it without shpping. (no axle or sliders.).
