Hello.
Here is one way to look up parts interchangeability.
As an example, lets say you want to look up the front fender for a 1985 kx500.
1. Go to
www.bikebandit.com 2. Under OEM Parts, Click on "Kawasaki"
3. Click on "Off-road"
4. Click on "1985"
5. Click on "kx500"
6. Click on "KX500(KX500B1)US"
7. Click on the tab that says "Body and Fenders"
8. Click on the picture that says "Fenders" under it.
9. Find the BikeBandit.com Part Number. In this case it is 804273.
10. Copy that number and paste it into the "Search bikebandit.com" box at the upper right side of the page, and hit the search button.
11. Scroll down until you see the "Fits Machine" link and click on it.
You will see that the front fender is identical to these:
1985 Kawasaki KX125(KX125D1)US
1985 Kawasaki KX250(KX250D1)US
1985 Kawasaki KX500(KX500B1)US
Repeat these basic steps for other parts.
As a side note, just because no other parts show up that are identical to the front fender does not mean that other parts won't fit.
A color, vendor, or style change will cause a different number to be used.
Hope this helps.
