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?
