upgrade to gsx sport suspensions??

[Guest]

There are alot of sweet deals on GSX 600/750 parts for front and rear suspensions.

Seems like a solid upgrade but a nightmare to fit. Replacing the front forks requires buying or customizing the triple tree? cant be bore out and slide the new shocks in that would be too easy right?

Have seen a conversion triple tree for like $700+ without the forks or wheel.

And for the rear maybe getting a fatter lighter swingarm and tire but do you have to worry about the chain being aligned and again being able to swap these out from '81 to '04 to present is unreal right?


Anybody have pointers, experience with this sort of project?

GSX front ends bolt right on, need to mod the steering stops

For the GSX rear wheel, a GS1100 swingarm is needed and yes, chain alignment via offset sprocket and trimming or swapping the sprocket carrier

What are your goals? If you're seeking a custom look, then what you're proposing makes sense. If, on the other hand, it's a purely functional improvement you want, then I think you're barking up the wrong tree. Far better to spend the money on springs, oil and emulators for the forks, and a set of Ohlins shocks for the rear. Good pads, SS lines and a good bleed job for the front brake.
Just throwing more modern parts on an older frame, without understanding what effect things like triple offset, fork length and swingarm angle will have is likely to result in a bike that may look cool but handles no better or even worse then the stock bike did.

On my 80 GS750E, I went with the front end off a 80/81 GS1100E (lots more adjustable), direct bolt on. No changing anything, Installed some Sonic springs, 10 or 15w fork oil and got a pretty decent front end now. Haven't done the emulator yet.

Yes that did cross my mind and considered it might be opening a whole new can of worms which is why i didnt start tearing it down without any clue. There are alot of new parts to buy if you dont get the whole section front or rear. Example buying just the swingarm that doesnt include pivot bolts, axle, new calipers, lines, etc.
It would be much easier to stay stock and functional by replacing the rear shocks with ohlins but liking the monoshock look. Thinking of getting the 07gsxr rear together looks like a close fit but no shock mount and still need to check frame fitting.???
