Dirt Digits actually makes this kit complete by adding the front plate and lower fork protectors for $150, not $167, whereas it normally comes without those pieces for $119.
So the first comments are accurate that seemingly no manufacturer offers a truly complete plastic kit. It took Dirt Digits to take the obvious step and offer them together.
I can't see any reason why plastic manufactures wouldn't take the initiative to make a complete kit complete, it just seems obvious.
The only kits I have seen complete are for the mini bikes like the CRF50 and the KX65/KLX110/RM65/DRZ110
