Streetfighter V4 (MY20) – Ducati Ducati Red

The Streetfighter is the result of the “Fight Formula”: the Panigale V4 stripped of the fairings, with a high and wide handlebar, 178 kg on the scale, powered by 1100 cc Desmosedici Stradale delivering 208 hp kept in hand by biplane wings and a complete electronic package.

The modern and technological Ducati naked bike has immediately enjoyed great success among motorcyclists all over the world, also confirmed by the positive feedback from the international media.

All models in the Ducati Streetfighter V4 range have become compliant with the Euro 5 anti-pollution legislation.

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.

Ready for the challenge

There are a multitude of engineering and technological aspects conceived for this champion road bike. A balance of distinctive lines, brutal output, state-of-the-art technology and components have been combined in this “Fight Formula” of the Streetfighter V4.

Design – Powerful & Thrilling

The Panigale V4 stripped of its fairings and with high-and-wide handlebar. This is the design concept behind the new Streetfighter V4, a bike that can amplify the emotions of its rider and make them feel like the leader of the pack on every outing on the road. The result is an unrivalled, contemporary, technology-packed naked bike, with a powerful and exciting design that does nothing to hide its performance.

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.

Aerodynamics – Racing Derived

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. These aerodynamic appendages generate 28 kg of downforce at 270 kph (20 kg on the front wheel, 8 kg on the rear). The wings also help draw heat off the engine by increasing water and oil radiator throughflow speeds by 2% and 10% respectively.

Engine – MotoGP Derived

With the arrival of 2021, all the bikes in the Ducati Streetfighter V4 range become compliant with the Euro 5 anti-pollution regulations, keeping the maximum power and torque values unchanged, but repositioned at different speeds.

The Streetfighter V4 Euro 5 delivers 208 HP (153 kW) at 13,000 rpm (250 rpm higher than the EURO 4 version) and a torque of 12.5 Kgm (123 Nm) at 9,500 rpm (2,000 rpm lower than the EURO 4 version). These values, obtained thanks to a new calibration and the new exhaust, make the bike even more enjoyable on the roads all curves

The silencer, unchanged from an aesthetic point of view, uses oversized catalysts (+10 mm in length) and a new technology of insertion of noble metals, essential to maximize the ability to convert polluting gases.

Also in favor of reducing emissions, the introduction of 4 lambda sensors, one for each cylinder, which allow a more refined control of the quantity of fuel injected.

Chassis & Ergonomics

Compared to the Panigale V4, the riding position – with an above-ground height of 845 mm – has been redefined as per the specifications of a naked model. In keeping with streetfighter culture, the semi-handlebars have been replaced by a high, wide bar that, together with a seat with 60 mm of foam thickness and moderated footpeg position, ensures sports-style comfort during inner city rides and the control needed to tackle country roads or racetracks.

While maintaining many of the Panigale’s stylistic features, the tail is supported by a steel subframe and has been redesigned to enhance passenger comfort and give the rider more lengthways space.

Front Frame

The key advantage of the Ducati Front-Frame is that it uses the Desmosedici Stradale engine to achieve the desired stiffness: this has resulted in significantly lower main frame length and weight and a better stiffness/weight ratio. Moreover, the struts alongside the engine have been shortened, making bike design more compact, especially in the rider’s seat area.

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.

With this latest model, 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.

Sophisticated suspension

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 Streetfighter V4 S, instead, is equipped with an Öhlins NIX-30 fork, an Öhlins TTX36 rear shock absorber and an Öhlins event-based steering damper.

Wheels & Tyres

While the Streetfighter V4 mounts cast aluminium 5-spoke wheels, the V4 S is equipped with 3-spoke Marchesini forged aluminium alloy wheels.

The rims mount Pirelli Diablo Rosso Corsa II tyres. Combining track performance with road versatility, they come in the 120/70 ZR17 (front) and 200/60 ZR 17 (rear) sizes, already used extensively for slick tyres in the FIM Superbike World Championship.

The rear tyre compound has been designed by Pirelli specifically for the Streetfighter V4. It ensures the same dynamic behaviour as the Supercorsa SP race replica tyres mounted on the Panigale V4, but has better low temperature performance to ensure the versatility one expects from a naked.

Electronics

The latest-generation electronics package on the Streetfighter V4 is based on a 6-axis Inertial Measurement Unit (6D IMU) which instantly detects the bike’s roll, yaw and pitch angles.

The electronics package has controls for every part of the ride: some oversee start, acceleration and braking, others govern traction and others again lend a helping hand on corners and out-of-the-corner stretches. 

• ABS Cornering EVO
• Ducati Traction Control (DTC) EVO 2
• Ducati Slide Control (DSC)
• Ducati Wheelie Control (DWC) EVO
• Ducati Power Launch (DPL)
• Ducati Quick Shift up/down (DQS) EVO 2
• Engine Brake Control (EBC) EVO
• Ducati Electronic Suspension (DES) EVO 

Operational parameters for each of these controls are associated by default with the three Streetfighter V4 Riding Modes. Riders can personalise parameters to suit their riding style or restore Ducati factory settings. DTC, DWC, DSC or EBC control levels can be adjusted quickly via the left switchgear.

The Streetfighter V4 features the same 5″ full-TFT high resolution colour screen (186.59 PPI – 800xRGBx480) as the Panigale V4. The rider can call up two different lay-outs for the screen: ‘Track’ highlights the lap times and the rev counter scale makes the revs typical of track use more clearly visible; ‘Road’, instead, replaces lap times with info on the Ducati Multimedia System (DMS), where present, and the rev scale is more appropriate for road use.
