Update!!
I emailed Penske Shocks requesting information about what other bikes this unit would work with. Their answer is pasted below.

* ’98-’04 Kawasaki ZX6R
* ’05 Kawasaki ZZR600
* ’00-UP Kawasaki ZX9R
With some small modifications to the clevis and by drooping the shock so it is shorter it could fit-up on the following:
* ’98-’99 ZX9R ($7.50 DROOP + SERVICE FEE)
* ’04-’06 ZX10R (CLEVIS, DROOP & SERVICE FEE)
* ’06-’08 ZX6R (CLEVIS, DROOP, & SERVICE FEE)
Cost is $95 service/rebuild fee.
Hope This is helpful for you, If you have any other questions feel free to email back or give us a call 610-375-6180
