yupp,
The 07 kx 85 is front sprocket PN#13144 14t
Rear PN#42041 49t and a
420x120L chain
The 08 is the identicle PN#'s and there are several options avail for more / less teeth on sprocket.
I go to a website that offers the OEM parts and pull up a parts diagram, minimize the window and open up another window with the other model you want to compare.
open both windows on your desktop and compare side by side. you can also find all the models a part will fit if you use the kawasaki.com part diagram and click around a bit.
Hope this helps,
