Thats are `vertex` pistons. www.google.nl search on vertex piston

It's probably just sprayed with graphite. Or maybe is anodised (=ceramic, but slim layer) and dyed black. I don't think any of these options is much beneficial.

Yes you are right ,the simple graphite coating is good for-running in only, or the tin coated Asso.. But the ceramic is really good for durability, performance, and heat conduction..

There was also availible graphite spray for pistons; some cross racers applied it when rebuilding top end (every race). But with questionable results.
I wouldn't have the piston skirt anodised, AlO is very hard, probably it would wear out the cylinder much sooner. But ceramic coating is very good on the top of piston, to insulate the crown from overheat.
