Well I am sure there is a good amount of people looking for answers if this is possible or not and yes it is in fact possible to put YZ250f or YZ450f plastics on your WR. Theres quite a few things to do/must be done inorder for this to work. I chose to do the because my WR426 is a supermoto but I wanted to change my color scheme and kinda update the look so I chose black and white plastics. Overall it isnt that costly unless you decide to buy everything listed below brand new.
For starters you're gonna need these things from and 03-05 YZ250f or YZ450f.
-Rear Side Panels
Once you have all of that, then the fun begins. I'll try and walk everyone through this to the best of my ability and I will post pictures, its a project in the making on my end also. I know there are a couple other threads out there but hopefully this helps/answers some of your questions. There are some little tweaks/trimming and brackets that need to be made for a safe secure fit of the tank and shrouds. With this being said, lets begin!
This thread will also help you greatly with wiring in lights, turn signals, brake lights etc: http://supermotojunk...(electrically)
Very good write up^ I'll try and cover my wiring set up also.
