The lowers are made by Powerbronze (Link for S2 Fairings), they are a glossy black plastic. I added vinyl wrap to break up the "slab-side" look, but where the silver wrap is it gets too hot and peels off pretty frequently.
Some of my other mods:
FZ1 handlebar
Manual cam chain tensioner
RaceTec fork springs and gold valve emulators
Braided front brake lines
Also cut a couple springs out of the throttle return spring
Pretty much everything I've done to it has been either maintenance, suspension mods, or ergonomic mods.
