2021 Model Year
To comply with the new European standards on pollutant emissions, as of 2021 all the Ducati Streetfighter V4 range models now comply with Euro 5 anti-pollution regulations.
New front brake pumps and a self-purging clutch have also been introduced, both originating from those used for the first time on the Superleggera V4.
The inspiration: Joker
The minimalist design of the full-LED headlight perfectly captures the essence of the Streetfighter V4 – reminiscent of the Panigale V4’s front end and at the same time evocative of the deranged look of the comic book character who inspired the designer of the Ducati Design Center in creating the new naked from Borgo Panigale: the Joker.
The Ducati signature style is represented by the V-shaped DRL which already characterises the Panigale V4 and SuperSport.
The compact front light unit is housed in a carefully designed double-layer fairing that accommodates the air inlets for the airbox and for cooling the LED lights, while a rear deflector ensures that the air flow is not aimed straight at the fuel tank.
The headlight is mounted on the 5” TFT instrument panel (the same as the one used on the Panigale V4) featuring a sophisticated front over that stylishly conceals the connections and wiring.
The low forward angled front mirror the lines of the fuel tank to give the Streetfighter V4 the look of a predator awaiting to pounce.
The Front Frame and the Desmosedici Stradale are kept as much in view as possible, partially covered by minimal fairings and covers with sharp lines and sculpted volumes that create an uncluttered, essential look. The F1-derived air extractors stand out from behind the radiator.
They have structural function, connect directly to the frame and incorporate double stacked wings – another MotoGP-derived element – that generate the vertical load necessary to ensure maximum stability at high speeds. The colour scheme with the double red area with the black extractor in the centre emphasises the dynamic look of the bike when viewed from the side.
The Panigale V4, stripped of its fairings and with high, wide handlebars. This, in short, is the underlying concept of the new Streetfighter V4, a bike that magnifies the thrill of the ride every time it takes to the road.
The result? An unrivalled naked bristling with cutting-edge technology and an awe-inspiring design that oozes pure performance.
The minimalist full-LED headlight captures the spirit of the Streetfighter V4 perfectly. On the one hand, it recalls the front of the Panigale V4 and, on the other, evokes the crazy grin of the Joker (the comic strip character from which the Ducati Style Center drew inspiration for this new Bologna-built naked). Already featured on the Panigale V4 and SuperSport, the V-shaped DRL is another clear Ducati hallmark.
Fast, agile mixed-road performance demands maximum stability at high speed and when braking, reduced wheel-up during acceleration and minimised electronic control of the suspension set-up: that’s why Ducati Corse specialists have, together with the Ducati Style Centre, developed biplane wings for the Streetfighter V4.
The aerodynamics were developed using CFD (Computational Fluid Dynamics) simulation. The calculation method involved stationary simulation of flow and pressure to achieve increased downforce, especially on the front wheel.
To reduce lateral protrusion as much as possible, the aerodynamics team decided to adopt a ‘biplane’ configuration of limited ‘wingspan’ with upper and lower wings working independently.
Each appendage can be described as a square-plan mono-wing with a winglet on its outer tip. Moreover, the wings have been positioned as close as possible to the front wheel (near the radiator side panels) to maximise the anti wheel-up effect.
The Streetfighter V4 mounts 43 mm Showa Big Piston Forks (BPF) to provide full adjustability in spring pre-load and compression and rebound damping.
The fork bodies house chrome sliders with Brembo radial caliper mountings. A Sachs steering damper completes the front-end package. At the rear there is a fully adjustable Sachs shock absorber, one side of which is attached to the Desmosedici Stradale engine via a forged aluminium bracket.
Wheels and tyres
While the Streetfighter V4 mounts cast aluminium 5-spoke wheels, the V4 S is equipped with 3-spoke Marchesini forged aluminium alloy wheels.
Braking system with Brembo Stylema® callipers
The StreetFighter V4 range incorporates the powerful Brembo Stylema® monobloc callipers that represent the evolution of the already high performance M50 callipers.
Brembo double callipers have four 30 mm diameter pistons each and work on 330 mm diameter discs for an unparalleled braking power. Whilst the rear system incorporates a single 245 mm disc with a 2-piston calliper. The braking system is supported by the ABS Cornering EVO system, which uses the lightweight 9.1MP control unit.
With the MY2021, new front brake pumps and a self-purging clutch have also been introduced, both originating from those used for the first time on the Superleggera V4. The new pump unit has been designed with a unique configuration to allow “natural” purging, hence eliminating the need to intervene on the system if any air gets into the circuit
