I am in the process of getting my 03 WR450F street tard and had some questions about the plastics. I know you can put a YZ rear fender on the WR, but is there any difference in the radiator shroud plastics on the WR and YZ. I know the tanks as slightly different, Will the YZ shrouds go on the WR tank? And will a YZ tank go on a WR? I kind of like the look of the smaller YZ tank.
