So, bottom line... why does the parts fiche show my bike having a different swingarm than what (seemingly) was actually installed at the factory? Whats the story there? I think this is mainly an academic question, all the parts (bearings, spacers, seals, etc) are identical between the two years/styles. The only difference is the '82 (square aluminum) swingarm fiche doesn't show a washer used under the head of the swingarm bolt, just under the net (and the '81/tube swingarm shows a washer under both).

81 GS1100E... which swingarm do i have??
So I have an 81 GS1100E that i bought earlier this year. A previous owner has done some work converting it to a "cafe" style bike, so its not stock, but so far most of the mods have been appearance, and the suspension/drivetrain/chassis all seems pretty much stock from what I can tell. But this bike has been my entry into the GS world, so not like I'm an expert. My next project is to replace rear shocks, new sprockets/chain (and a conversion to 530 chain), and while I've got it apart was going to replace the wheel bearings, and contemplating replacing (or at least inspecting/greasing) the swingarm bearings. So i'm on the parts fiche looking at what bearings, seals etc would be needed, how its all put together and such. And I notice the swingarm in the drawing looks nothing like mine, and googling of the lsited part number looks nothing like mine. The parts fiche shows a tubular (steel?) swingarm, but my bike has an aluminum swingarm of a rectangular cross-section. And this matches photos of stock/new '81 GS1100Es, so I'm guessing its correct/original. But digging through the parts fiche, I need to go to an '82 1100E to find a swingarm that looks like mine.
So, bottom line... why does the parts fiche show my bike having a different swingarm than what (seemingly) was actually installed at the factory? Whats the story there? I think this is mainly an academic question, all the parts (bearings, spacers, seals, etc) are identical between the two years/styles. The only difference is the '82 (square aluminum) swingarm fiche doesn't show a washer used under the head of the swingarm bolt, just under the net (and the '81/tube swingarm shows a washer under both).Tags: None

The '81 GS1100E sitting in my garage has an aluminum swingarm. Pretty sure that is what was stock on that bike. Same swingarm that was on the '83 GS1100E I used to have, I believe. Parts drawings are not real exact and some get re-used from one model year to the next for some reason???Last edited by 1978GS750E; 12-01-2021, 10:21 PM.Ron
When I die, just cremate me and put me in my GS tank. That way I can go through these carbs, one more time!https://www.thegsresources.com/_forum/core/images/smilies/cool.png

Cycle World called the '81 a "built-up box section aluminum" swing arm and I'm rather certain it is identical for '81, '82 and '83. Probably for 1980 as well.1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

Yep, all 16 valve 1100's had alum., even the L's". Quickest way to tell difference, at a glance, in the Gs750 16 V & a GS1100 16V, in those yrs. as all body parts were identical, was look at the swingarm, all the 750's had the steel.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw.

I checked the parts fiches at Babbits/Suzuki Parts House, Partzilla, and CMSNL. All showed the '81 having a tubular swingarm, with a diff part number from the rect. aluminum they show for the 82.

Are you SURE you have an '81? I ask that because mistakes are not uncommon when a title is issued. Some states will call a bike an '81 if it's sold in '81, regardless of when it was actually built. Can't go by the build date, either, because production of the '81 bikes started as early as August of 1980. Suzuki is also the master of "parts bin engineering", and also making up differences on the assembly lines. Maybe they ran out of aluminum swingers that day and had to borrow some from the 750 line?
And, unless you are the original (and ONLY) owner, who knows what somebody has done.

As I recall: Every 16-valve 1100 had the built-up square section aluminum swingarm. This was a New Idea from Suzuki. No manufacturer had used a swingarm like that previously. The 16-valve 750s (and all smaller engines) used the round-tube steel swingarms.Expecting the Spanish Inquisition

I know the KZ guys have been adapting the GS swing arm to their motorcycles for years. Pushing the price up to $200+... I'll hang on to my stash a little bit longer. Unless someone really wants one... 👍My Motorcycles:

TeamDar, I sure thought I remembered the "80" GS1100LT had the alum. swingarm, I didn't trust your opinion. I looked at the photo gallery, on this site, & it sure looks like you are correct. No perfect pictures but they sure do look like they did have the older style steel tube swingarm. Thanks for bringing this out.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw.
