'92 - '94 ZX7 shocks fit for sure. Just do not confuse the standard ZX7 withe the ZX7R. The "R" uses a remote reservoir shock. And I am sure that there are others out there! I just took a stab at it one day by taking a few measurements of my stock shock and searching e-bay. I came across a couple of pics that had a ruler placed next to a ZX7 shock. It looked close, so I took a gamble. Somebody else here has used I think it was a ZX12 shock with remote preload adjustment and had to do a little modification. Yet another person here has fitted a remote reservoir shock by relocating the battery box.
Some of the ctritical dimensions are: the shock spring diameter (a very large diameter spring/shock probably will not fit), there must be an eye at the top and a clevis mount at the bottom (2 eyes = no good), The over all length should not be much longer than the stock shock (a little bit longer is Ok, like the ZX7 shock, but another inch or two would not be good), and remote nitrogen reservoirs of any kind will make life difficult for you.
Overall, I am very happy with my $20 ZX shock. The adjustable rebound damping makes a huge difference in the ride quality and allows me to adjust my ride from a bit bouncy for cruising, to a bit slower acting for more spirited riding. I have not had the need to purchase a stiffer spring.
Anyway, as far as these bikes go, your choices are a cheap ZX shock or a $400+ Hagon. I do not doubt that the Hagon's are worth every penny, but it just kills me to put a nice piece of bling like that on a $2500 bike.
You could always buy the ZX shock off of e-bay and then send it out to Race Tech for a full rebuild with a Gold Valve. I am sure that it would rival a Hagon.
Race-Tech/Paul Thede=Good Stuff! I have used their Gold Valves on my dirt bikes with surprisingly good results. You can also source parts for the ZX shock there.
