this is the swingarm on the next bike I building. It doesn't look like any swingarm I have seen. I can't find any numbers or anything thanks guys

If it helps the frame is a 1980 gs1000g

It looks like am shaft drive frame to me.

Yea I got that, but it's square swingarm vs all the others I have are tubular. It is totally different than my other 1000g swingarm

Crap no one knows?

Weird....

Been digging through some part numbers, and I don't think it's a substitution from a different Suzuki.

61100-45820-019 is the original part number for the 1979 GS850G, and the same swingarm is used on 1979-1981 GS850 and GS1000 G and GL models.

This superceded to 61100-45870-019 , which is used in 1982-84 GS850, GS1100 G/GL/GK.

Both appear to use round tubes.

81-83 GS650 G/GL used 61100-34841-019, but this appears to use round tubes as well.



Lots of other oddities in this one as well -- that long gusset on the left where the final drive mounts, and the longer, large-diameter tubular section where the u-joint inserts. On all shafties, the front gusset is all one piece -- from the curve in front of the tire to the pivot is one boxed-in piece.


I think that's a clue -- I'm guessing this is a custom extended swingarm someone built.

What's the measurement between, say, the center of the pivot to the center of the axle? Do you have the driveshaft, and does it show signs of being lengthened? (Or what's the driveshaft's length?)

A very unusual swingarm indeed.

I'm leaning towards Honda - looks vaguely like a cb650 nighthawk

The shock absorber mounts look very "honda-ish"

Yamaha XJ very similar too

I guess the real question is will one of the driveshafts and final drive units I have fit this. Does anyone have any real concerns based on the photos of just running it? I will get measurements this weekend, the frame is at my dads awaiting powdercoat and having the side panel mounting tabs welded back on, someone has cut those off

^wow. I looked at approximately 54,792 swingarms on google and couldnt figure it out.

So is this a notable swap?

I just looked at the swingarm fische on Alpha Sports and will agree with this suggestion.

Wow, thanks guys! now the question is if I should use this one or a regular GS swingarm
