ZRX shocks will be way to long and the spring way stiff for a 650.
I will measure both my SR and ZRX tomorrow morning and report back on the length.
ZRX should be about 14 1/4 to 1/2 in. and SR 12 1/2 to 13 in.

buy haveing the forks above the top tree, it makes it steer quicker (easier.) put them where u like the steering action best. the down side to having the forks above the trees is that u loose some ground clearance.
u could give the zrx shock a try . if u are not happy u can get your money back through ebay.
i have them on my kz1000.they are about 1" longer than my stock shocks.
since they are 1 inch or more in your case ?, longer, i would put the forks back to the stock position.

has anyone else done this mod?

Might simply raise the rear end without adding any additional suspension travel. And which usually quickens the steering (which might aggravate head shaking tendency).

The spring rate may be a more important consideration.

Sometimes it helps to equally increase the pre-load on both shock springs.

Good Fortune!

so if im looking for aftermarket shocks its probably not the best route to go?

i noticed yesterday while looking at my bike that the forks are about 3/4 inch ABOVE the upper triple. i looked in the manual and its supposed to be JUST BELOW the upper triple...this is how i got the bike and i assumed this was how it was supposed to be, should i raise it back up?

I've have the same bike and have had the pleasure of those shocks on my own ZRX and even though I haven't had them together on the same bike I can only say that compared to stock shocks it would have to be as much of an improvement as you can imagine. Tim has just got this bike back together and will be giving us all a review on as much of the bike, etc. after his long haul trip he is taking on it.

How are the shocks working out for you, do they work better than the stockers? Great pinstriping job BTW.

Down the road I'll be doing some things to my own ST, you're definitly an inspiration.
Best,

The shocks are original Kawi equipment (made by KYB) on the 2000era ZRX 1100 and 1200's.

Pinstriping was done by hand by Greg Sabatini at Sabatini Autowerks in Rowlett, TX. Haven't had a chance to test the avons yet but I'll let you know.

We'll try! Knowing our luck we'll probably get a moose this year :laugh:

I would of slanted the shocks more forward to raise the back end a bit or rotate the eccentrics.

in the newer pick i have the shocks laid down more at the top, towards the front.
u have to remember that this frame is dif.than the zrx.
i copied the shock angle of the zrx, so the shock action is the same as yours. but this brought issues . the output sprocket to swingarm axle spacing is dif. on modern bikes, so this causes chain tension issues as u raise the rear end, above the stock kz geometry. i had to run the chain looser, and add a idler wheel, to pick up the slack. raising the rear also lessens the rake . i had to modify the front trees to try to gain some of the lost clearance, and level the bike a bit. the clearance is not a big deal on the street , but huge on the track. the front end isnt bad but it could stand a little more trail.
thanks for the kind words.

Very nice bike.

I was thinking of doing the same to our 73 Z1, Rear swingarm and wheel off of ZRX and front forks too..

But she shot down the idea. I will keep working on her.

Really like the bike!
