Well it is 100% not a genuine Superleggera. Subframe is a real give away as is the front frame, neither of which are full carbon. Rear wheel cover is hideous IMHO.
Leggera and frame etc I know nothing about, but the rear wheel cover is double hideous and has made my eye hurt!
Wasn’t the guy who sells all the wsbk stuff selling those for about a grand a piece as ex Chaz Davies items..
Although Tbf I’m not sure it’s actually the worst part of that bike!! wtf are those taped on wings about and those brake ducts…
Dunno about the dustbin lid, all I can see are the woos-lines on the rear tyre. He'd be fine with a 160...
The wheel covers are available in the States. The guff that goes with the product page is unbelievable. https://shift-tech-carbon.com/products/st5000-19-fullsix-carbon-ducati-aero-wheel-disk-gloss
The average mass/volume of the wheel plus cover is less than the average mass/volume of the wheel alone ( carbon fibre is lighter than alloy) Simples
