Gifrap Footrest system?

I searched and didn't see any info. Does anyone know what's up with these? [You must be registered and logged in to see this link.]

I've got Knight lowering pegs on my bike but have been searching around for adjustable footpegs since the Knights are a little too rearward for me. I stumbled upon these and am really just curious about them. I'm still learning the GRiSO but it looks like these bolt on in place of the massive "rearset" plate the stock pegs mount to. They don't look adjustable but does anyone know if they change the footpeg location from stock?

I couldn't find a website for this company or any info on them. I'm thinking they must be old stock from years ago when the GRiSO was new...
