If by billet he means aluminum, yes, I think they are. They look and feel it and are nonmagnetic.
A billet is actually just a chunk of something, like aluminum. Or wood. So many things are CNC'd from a billet of aluminum nowadays, I think the meanings are becoming synonomous.
BTW, I also like the feel of the broad Roadster levers.
I think by billet , they mean machined from the billet block.billet items are usually more expensive, being machined. I suspect the R3 levers are just pressed metal?
I think most things like that are cast,its the cheapest way to do it for mass production.
If they were low volume custom levers ,they they would be machined from billet.
Anodising can give unpredictable results on castings - depends on properties and densities.
Good 2-part epoxy spray paint or ceramic is probably tougher anyway. I'm in a similar dilemma as the lever "blacking" on my 1979 Guzzi is wearing through.
I might have to go the spray paint route Barbagris, as I can't see any sensible way of removing the flared connector that holds the lever adjuster in position. I think I might be able to mask it off for spraying though. Is there a chemical alternative to emerypapering everything, as there are a lot of nooks and crannies.

Drill it out and replace with a bolt?. I'd be cautious of aggressive chemical strippers on Aluminium. Good Epoxy paint will only need the original surface to be keyed not stripped right back. There are some REALLY good surface finishes in the firearms business. http://www.lauerweaponry.com/
I've not used Lauer stuff - I've used others (KG coatings for example) - but they require clean metal and really need oven curing.
