The GS1100 swingarm uses a clevis mount shock, ZRX shocks won't work for this application.

Mr. Wog?! Yeah, I called him about lowering a zrx seat. I have seen his work. It is really good. You have a zrx too? I notice the shocks. How about some more pics of the whole bike?
I just picked up two zrx's over last summer and the season past. I loved riding them so much I kind of forgot my kz. So much money on that bike to be spending and not getting where I had imagined. That last build I thought would be the last for many years yet something happened and now I can guarantee you if I have the same issues within 10k I am going to be really POed.

welcome fritula!

the longer forks can keep the bike closer to the stock ride hieght.which will give you more cornering clearance.which depending on your local roads may be a plus.

the shorter forks are going to lower your bike,and the zrx shocks are going to raise your rear end.which will reduce your rake and will make your bike steer quicker.

hopefully i have helped you understand a lil more.

He paid a good price for them.

those look like ZRX11 or 12 shocks

here is a link to some details

here is the bushing, or sleeve that i had made up.



i relocated the top shock mount to the more forward spot that can be seen in the pic below. this gave the shocks the intended geometry ,and softend the ride nicely.

they have researchech and suply bearings for doing front end swaps, maybe if u called they could come up with something for u ?

Ah yes, an update....

I did everything I could to find ready made bearings to no avail. I did not look into having anything made though. The local bolt and bearing houses (2) could not do anything for me, and searching online I only found a few that were in far away countries (Poland, Hungary, etc). There were a few I found closer to home, but they were listed as 'camshaft bearing' for Aprilia and a few oddball bikes... I'm not sure what those were, but I'm pretty confident I wouldn't want to be doing 80mph on them in a swingarm.

So after another week or two of hemming and hawing I finally came to terms with having mismatched wheels.
I found a good deal on a nice condition ZRX12 wheel and went ahead and got it. I figured with the three spoke curved design, that is very close to the 08-09 GSXR three spoke curve as well, just different thicknesses... but you could play that off as 'well, the wheels twice as wide, why wouldn't the spokes be thicker?'.
To get the 08-09 wheel on the front all I would have to do is use the 08-09 rotors to fit the 06-07 forks/calipers, so no big deal there.

So for now I have the swingarm mounted, had the KZ swingarm bushing machined down to fit the ZRX swinger and trimmed down the width about 3mm or so to fit the frame. I haven't decided on what I am doing with the rear peg brackets yet, as they seem a bit in the way.
I have KYB shocks in the mail, the rear wheel in the mail, and the ZRX cush sitting on my desk now.

Currently I still need to find:
ZRX12 spacers for rear wheel
ZRX lock clips for eccentrics
ZRX12 caliper bracket/spacer
ZRX12 caliper and thrust rod

Once I have all that, I can see where I am at with chain alignment and make some spacers for the engine placement to align it properly... currently I have the trans mounts gapped out ~1" each to allow for thrust that will be taken up with spacers, since the stock thrust nuts won't work in this frame.


Edit to add: the seizing issue is something I was just unsure of... I have seen on a few occasions sleeved stuff like this (not particularly bike axles) that seized together due to uneven expansion/contraction rates and chemical intolerance between two metals. even with a thin oil coating etc... I'm not a pro on stuff like that which is why I asked on opinions on it, but ultimately I decided even if its a 5% chance it is too risky since it is in an application where I could not simply press it out and start over... it would be permanently captive between those eccentrics.

looking good so far

I started with an 82 GPz750 frame and installed an 81 GPZ1100 engine, ZRX swingarm and shocks. Front end is also 81 GPZ1100.
Mark Wing did the paint, beautiful job I might add. I am almost done so here are the pics so far.

What I started with

Engine final mount in frame

Engine covers after sandblast and painting.

Mark is finishing up the tank and I hope to have it on the road by early next year

Contact Dave Quinn (see link below). He will set up a pair of Hagon shocks specifically for your weight (including the 2-up factor) riding style, accessories, etc., and he does this VERY well. I bought shocks from him a couple years ago and still love them; others have had the same experience. They are top quality shocks that come in a variety of styles, and they have stainless steel bodies. I can't say enough good stuff about them; they're great. Ed
