I finally gathered all of the plastic pieces to turn my 2016 WR 450 black. Well almost all of the pieces.
I couldn't find the white plastic cowl, fairing thingy that the headlight mounts to. All the ones I found in black had a headlight attached to them and they were very expensive so I decided just to paint the thing with Krylon super Maxx in gloss black and its worked out okay.
I had been looking for a kit that had all of the parts in it and that's what I couldn't find anywhere but once I found out there were black plastic pieces out there I just had to buy them one at a time I started looking for a place that had the most of them in stock and That place turned out to be "Rocky Mountain ATV MC". so I ordered all of the Acerbis pieces from them. The piece that I couldn't find besides the headlight thingy was the rear fender. I looked high and low for a black rear fender and was about to give up when I figured I would just buy a YZ450 fender and make it work. I did make it work but it was far from perfect, the way I had to mount the tail light was kind of ugly but the biggest problem was the battery compartment and all the electronic gadgets there are attached to the metal plate the battery sits on. The YZ fender is a completely different shape in that area and takes up a lot of space where the battery should be. The only thing that saved me was I had just bought a Shorai lithium iron battery and it's so tiny it fit in that limited space.
By the way I weighed the batteries on my postal scale and the factory battery weighed 4 lbs. 8 oz. and the Shorai lithium iron battery weighed 1 lb. 7 oz.
I'm really not liking the way the whole rear fender turned out so if I ever find a black one for a WR450 I will replace the cobbled together thing that I've got now.
All the other parts fit like they were made for it and went together quickly and easily. The weird thing is each part came in a bag with a label that said it was for some other model or some other year or some other size, the only thing that was labeled for my motorcycle was the front fender, But everything fit just fine.
