Rivco risers for 2015 roadster, where to buy them in US?

I sold all my R3 acc's summer b4 last and I think the riser was $225, but good luck finding them anymore outside of swap meets
 
They took the order but then sent an email that they are out of this item…so I guess it’s out of production now
What’s the alternative to
Improve riding position? Z handle bars or any other kind that does not require any cable mods? Or May be cable
Mods?
 
Earthquake, if interested in risers but not sure if there are Rivco or not. Send me phone number and I can send you pictures of what I got.
