Det första exemplaret av Ducati Superleggera V4, med en prislapp på 100 000 Euro och begränsad till bara 500 enheter, har rullat av produktionslinjen i Bologna, dit ägaren av motorcykel #001 var inbjuden för en speciell leveransceremoni.
Den rikligt kolfiberkittade modellen är den tredje i Ducatis superexotiska Superleggera-serie.
2014 föddes den första Superleggera, baserad på V-twinnen 1199 Panigale rikligt tillverkad av magnesium. Den följdes år 2017 av 1299-kolfiber-versionen och nu kommer även Panigale V4 i det exklusiva Superleggera-kolfiberutförandet.
Samtliga 500 Superleggera V4 kommer att drivas av en 221 hk stark V4 R-motor och kommer återigen att vara rikligt kittad av kolfiber, vilket sägs ge en torrvikt på låga 159 kg. Om motorcykeln dessutom förses med det superlätta titan-avgassystemet uppges toppeffekten öka ytterligare till 231 hk samtidigt som torrvikten minskar till 152,2 kg.
Ducatis pressinfo (på engelska) om Superleggera V4:
The Superleggera V4 is the only motorcycle in the world, approved for road use, with the entire load-bearing structure of the chassis (frame, subframe, swingarm and rims), made of composite material, obtaining, for these components only, a weight saving of 6.7 kg compared to those of the Panigale V4 MY20. To ensure the highest quality and safety standards, these components are 100% controlled by the most sophisticated techniques borrowed from the aerospace industry, such as thermography, ultrasound checks, and tomography.
The specific set-up of the chassis gives an unparalleled deceleration capacity, an extraordinary speed of descent when cornering and a marked tendency of the bike to close the trajectories when exiting corners.
Many components are made of carbon fibre , modelled in advanced aerodynamic shapes. These include the fairing, which reaches efficiency levels higher than those of today’s MotoGP bikes, which are limited in this by the current technical regulations. Thanks to the aerodynamic biplane appendages inspired by Ducati’s 2016 MotoGP bike, the most highly-performing in this field, it is able to guarantee a vertical load of 50 kg of "downforce" at 270 km/h, 20 kg more than that produced by the wings of the Panigale V4 MY20 and V4R. This downforce improves acceleration by counteracting the tendency to wheelie and increases braking stability.
The carbon fairings are embellished with a livery inspired by the Desmosedici GP19, with an alternation of lines and depths between the red colour of the GP19 and the visible carbon that highlight the shapes, the materials and the technical details. The red continues on the coloured sides of the OEM Pirelli Diablo Supercorsa SP tyres, specifically developed in the construction for the Superleggera V4.
The most powerful and lightest Desmosedici Stradale R engine is hidden under the carbon skin.The 998 cc 90° V4 unit of the Superleggera V4 weighs 2.8 kg less than the 1,103 cc V4 and, thanks to the Akrapovič approved exhaust, produces 224 hp of power in road configuration(EU homologation value), which becomes 234 hp by mounting the titanium Akrapovič exhaustfor track use, which is included in the Racing Kit supplied with the bike.
The racing connotation of the engine is emphasized by the use of a dry clutch and by the timing of the Desmodromic system made manually by a specialist who, after checking, confirms the positive result by affixing his signature on the metal plate that embellishes the carbon cover of the rear cylinder bank.
Only on the Superleggera V4, by loading the engine calibration for the racing exhaust, is it possible to enable the display of the "RaceGP" dashboard. Intended for circuit use only, it derives from that of the Desmosedici GP20 dashboard designed on the indications of Andrea Dovizioso.
Thanks to the extensive use of carbon fibre, components made of titanium, magnesium and others from aluminium billet, the Superleggera V4 shows a dry weight of 159 kg on the scale (16 kg less than the Panigale V4), for a power/weight ratio of 1.41 hp/kg. A record value for a homologated sports bike. In track configuration, by mounting the Racing kit supplied with the bike, the power rises to 234 hp and the weight drops to 152.2 kg, with a power/weight ratio of 1.54 hp/kg.
The electronic controls have also been evolved in a purely racing perspective. By default, the operating parameters of these are associated with three reprogrammed Riding Modes with specific names (Race A, Race B and Sport). In addition, for the first time five Riding Modes can be added, customizable with your favourite settings. The rider can monitor lap times through the evolution of the Lap Timer, which now allows you to store the coordinates of the finish line and the split times of five favourite circuits, so as to recall them every time you go out on the track without having to repeat the data logging procedure. By default the system proposes the coordinates of the finish line and intermediates of Laguna Seca, Mugello, Jerez, Sepang and Losail.
Added to this is a latest-generation electronic package that includes EVO 2 strategies for DTC and DQS up/down.
Öhlins lightened suspensions with pressurized fork and lightened billet foot and shock absorber with titanium spring and GP-derived valves are part of the equipment, which improve the absorption of road roughness in the initial compression phase.
The braking system is the best of Brembo production with an MCS radial pump equipped with a remote control for adjusting the distance of the lever and Stylema® R calipers, an exclusive of the Superleggera V4 that allows greater consistency of front brake travel in long runs on the track.
All this translates into a level of performance of absolute importance. Alessandro Valia, official Ducati tester, with Racing Kit and slick tyres, lapped the Mugello circuit in 1m52.45s , less than two seconds away from the time of the Panigale V4R SBK winner with Michele Pirro in CIV 2019.
An example of maximum attention to detail is the aluminium radiator cap machined from billet and the dedicated ignition key with aluminium insert on which the motorcycle number is indicated.
