Unabiker has some great designs! If he makes one for your model get it! For my bike I had to make my own version by combining Devols with Works Connection braces for more money! Brian may get to the WR450 soon. I was very impressed with his shop and attention to detail! He is working on a Carbon fiber air box cover for the wr450's which are prone to leaking badly around the cover seal due to plastic flexing and only 3 fasteners. An ultra stiff Carbon fiber cover will be awesome! Go Brian!
