Although I have no direct experience with this "Reckless" brand. I did take a peak at their site.
Their fairing seriously looks like a fairing I've seen before, but can't recall where. Therefore, Reckless may simply be a re-seller.
They list a unit for the VTX 1800.
I know the VTX 1300 triple tree and forks are very similar to the Valks. I assume the 1800 may be the same.
If you end up researching this setup on your own without any assistance from someone who applied it to a Valk you'll need to be aware of a few things.
a) Potential creativity required to get it mounted & functioning.
Read may = a lot of work!
b) Headlight opening. If it fits a VTX, it likely won't fit the Valks oversize headlight bucket. You may need to change out the Headlight to a VTX unit. Or an aftermarket headlight, which is very difficult to find a head light that will allow for the wire harness in the bucket.
c) Instrument relocation & cables and electrics.
Mine, from the
Trike Shop, took a tremendous amount of determination, modifications, $$$ and time. And, it was designed to
mount to a VTX 1300. And, I painted it myself with rattle cans from ColorRite.
Edit: There were very few other options several years ago when I did mine.
There are now a few more.
Woodys, a VRCC ad sponsor, is one and his is along the lines of the Reckless your interested in and is set up to mount the Phat Lady.

Rattle can color & clear takes longer to cure than professional painting w/hardeners.
Although, it had been wet sanded [to remove orange-peel] & polished at this point.
