swingarm

hello people; I'm new. In the past a SA upgrade was to go with a Suzuki GS 1000 alum. SA. I believe that was the model and I believe it was longer but did it change the shock location?

Location is about the same, but shock mounts are different. A lot of folks used the G S shocks since that is easier than replacing the mounts on the swingarm.

Honda goldwing shocks are also reported to work.

And yes it's approximately 2 inches longer

Click on the Phoenix Fighter link in my signature, I used a GS1100e SA on my KZ1000. I have links to products I have used. Feel free to ask me questions or for measurments. What ever you need to help out. Good luck with your build.

(Yes,Its the GS1100 not the GS1000) .The standard Z shock has an eye on the bottom of it which fits into a fork on the swingarm but the GS has a fork on the bottom of the shock which fits onto an eye on the swingarm.
When I compared the GS swingarm to my CSR swingarm,there was virtually no difference in length.
Good luck

the gs1100e aluminum swingarm 80-83 is almost two inches longer also a little wider. however kz shocks are eye to eye shocks gs shocks are eye to clevis mount. it is no big deal just get you a set of gs shocks with you swingarm. i've done that swap many times in the past. mainly because i could polish the gs arm and also run a wider tire. ive actually ran 180 series tires with them arms plus there lighter. good luck to you.

(Clevis-Thats the word I was looking for.)
My mistake about the length.They may be a couple of inches longer but what I meant to say was they are the same length from pivot point to shock bottom.
Also be aware that there is a GS1100 shaftdrive.You wont be wanting that arm.

78kzturbo,did you really squeeze a 180 tyre into the GS swingarm? I tried it but couldnt manage.I went for a GSXR600
arm in the end.

My question is are they stronger than Z1 KZ swing arms?

Yes, they a LOT stiffer than the stock round tubed KZ swingarms. I swapped one into my 650 about 20 years ago there is no flexing at all when I am running it hard in corners. The GS SA is boxed aluminum while the KZ is round tubing. The KZ one tends to flex when pushed hard, that is why you see them all braced up or simply swapped out on the early superbikes, My bike handles much better, I am sure the upgraded shocks I put on helps also but I am pleased with the end results and wished I had done this swap earlier.
The shock attachment points on the GS SA are about 2" farther back than the KZ ones so depending on the length of the shocks you choose, the bike can sit a little lower. I opted to have shocks made by YSS and got them 13" from eye to eye, this sits my bike just a little lower than stock.

Normally not too into red bikes, but really like what you've done!!! The black on the swing and pipe almost seem to make them dissapear into the bike!
