Here is a GS750/1000 rear wheel circa 1978 ish

can you tell me what swing arm it is or from what ?

i know the GS range was round from that era not square it would help me identify the one on my GT750

Sorry Von, can't help on the swingarm in the photo - except that there's a mod there to jack up the back of whatever bike it's on....

Going back to the other photo you posted of your bike though, I could be wrong but the spoke pattern of the rear wheel looks yamaha-ish to me, could the swingarm be off a yammy? Check it out for tuning forks!

But the rear wheel on your GT is off a GS750T. The old gs custom jobbi.

I recon the swing arm is a performace aftermarket job. I dont remember anyone using box section & twin shocks & if I remember right the japs never started using box section until the early 80's

nice input chaps..

will have a look out for tuning forks on swing arm. i know Mr suzuki started putting disc brakes on rear wheel late 70's again.. think the first disc brake on the rear was on the T10 250 circa 1964/65

this is the rear of me GT750...

Hmmmmm, I see where you're coming from Ronni. GS750T had a drum at the rear, but those spokes are joined into 5 pairs, Von's are not. I'm sticking with Yammy for the wheel, 80-81 XJ400/550 before they went curvy like RDLCs? Maybe........??

As for the swingarm, Von's new piccy shows a lot of fresh air on the right side, looks like it was probably off a bike with a disc brake? Does the swingarm have any obvious modifications or unused brackets/mounting points on it Von?

thanks Dr grimm.. my GT dose have 5 sets of twin spokes like the ones on the GS750T.. did not see any mods on the swing arm or lugs with out bolts in.

your close with the XJ400.. but it dose have a ridge in the center where the air valve is.... were mine dose not see pic of XJ400

the XJ550 has curved spokes.

the GS750T is the nearest yet..

until i can get access to the bike (as my mate has gone away on holiday) I'll
have to keep guessing !!!

If I remember right the Katana 1100 of around the early 80's had a box section swing arm. AND twin shocks. Painted grey as well if I remember right?

Allso remember nearly every Katana I saw had a after market braced swing arm. So I imagine quite alot were ditched.

OK, I'll shut up about the wheel, :confused:

I reckon Ronni's on a winner with the Katana swingarm, though. :D

is OK Dr Grimm all help is welcome, yours & RonnI's help has been most helpful to my problem..

at the end of the day think i may just get a GS1000/750 back wheel & disc brake and get the frame altered to suite the rear master cylinder.. that way it would match the front end..:)

Ho have sent a E-Mail off to the chap that owns that rear end on that pic of the GS 750 with the square swing arm... never know he may get in touch.. don't see any harm in asking.. :)

is GSX1100E. The 1100E (that is ET,EW,EZ not ESD or EFE)had rear disc ,box section and twin shox but think your pic is deffo Suzuki wheels although not totally convinced swingarm isn't after market like Ronni sez.Could be the 750 of course but this had an 18" rear wheel where the 1100 and 1000 had a 17".
"I'm not being much help am I ,dad ?":no:
OK so I've added nothing at all to this convo but this is kinda my era and I love these big ole suzy fours!(Oh and triples of course!)(anyone for tea?!)

DAD !!!! you'll pay for that Max.. ;)

well got me reply from the feller.. he don't have a clue what bike the swing arm is from... but he dose need swing arm bushes!!

still was nice of him to reply to me... all be it I'm none the wiser.. :eek:

on a up note.. I can shoe horn a GS750 back wheel onto the swing arm and make a pair of wheels the same type front and back.... sweet.. :)

so far.. front end defenetely suzuki think from a GS1000... size- 100x90x19" twin disc's 11" die 4.5mm thick..

rear wheel is a Italian MELBER alloy size 120x80x18"..drum brake

swing arm... god knows ? will strip it down and look for the make.. the drum brake brace arm is on the under side of the swing arm.. and the GS range of that area was on top of it..

the chap i spoke to re the GS750 wheel ..the blue one on the squire swing arm..
well he sold me the wheel & disc.. i have a matching pair of wheels now..:)

the next fine day i get off work.. I'll strip the bugger down and start from scratch.
