125-200cc When did they body/parts change

I have an 02 wr125. Wondering what year do the parts change? And body style? And curious if I could take a new body style. (tank and plastic ) and if it would work on my 02 frame. Meaning bolt right up? Any thoughts?

perhaps someone else could confirm but i believe plastics changed with the colour scheme 2006 and frame changed (white frame) 2009.

All the two stroke had plastics change in
1995, not sure any difference to earlier models.
1998( Different radiator shrouds),
2000( Different Rad shrouds, side panels, rear fender, front fender, subframe, tank & seat)
2005( Different Rad shrouds, side panels, rear fender, front fender, tank & seat)
2007( Colour change)
2009 ( Frame colour)
I'm not too sure from here on.

So if I'm reading that correctly, everything from 2005-2009 should interchange?

I believe so.
The best thing to do is to find someone who has a bike/plastics the year you want & start swapping plastics to be 100% sure before ordering anything.
