Ducati's replacement for the ultra-exotic Panigale V4 is here as the Superleggera V4. Superleggera is a term most often associated with the Italian ultra-lightweight method of constructing sports cars, but here it's absolutely deserved — the Superleggera V4 is the first street-legal motorcycle to use a carbon fiber frame and swingarm, taken directly from Ducati's MotoGP racing program. The MotoGP-derived V4 engine makes its return as the most powerful ever offered by Ducati, making up to 235 naturally-aspirated horsepower with the track-only kit installed. The Superleggera weighs 35 pounds less than the previous Panigale, thanks to lighter Ohlins suspension with titanium springs and the afore-mentioned carbon fiber. The bodywork features the aerodynamic wings seen on racing bikes in recent years, and electronic aids like rider-programmable riding modes make the Superleggera the most advanced bike Ducati has ever built. Limited to 500 units, something like this may never be seen again.
