The Streetfighter V4 S is the premium naked sports machine from Italian manufacturer Ducati. Not only is it one of the most desirable motorcycles in the 2021 Ducati line-up, but it’s also one of the most powerful factory streetfighters on the market. Like almost all other Ducati motorcycles, the Streetfighter V4 S features exotic styling, a powerful engine, and distinctive Italian design language.
Though it shares most of its DNA with the base model Streetfighter V4, there are some differences—but we’ll get to those in a second. Under the hood, the V4 S uses Ducati’s 1,103cc Desmosedici Stradale V4 engine that produces 208 horsepower and 90.4 lb-ft of peak torque, with all of the top tier riding aids and electronics that Ducati has to offer. These include traction control, riding modes, cornering ABS, and much, much more.
The features that separate the Streetfighter V4 S from the standard V4 are numerous. The most obvious and noticeable include the upgraded suspension. Instead of Showa units, the V4 S is fitted with fully-adjustable Öhlins suspension at the front and rear. Other notable upgrades include the addition of Marchesini forged rims and the addition of lighter weight components that enable the Streetfighter V4 S to weigh 5 lbs less than the standard version. Also, the Streetfighter V4 S gets a new color option for the new year.
For 2021, the Streetfighter V4 S is available in standard Ducati Red, as well as a blacked-out Dark Stealth option.
The 2021 Ducati Streetfighter V4 S starts at $24,395 USD / $28,395 CAD.

2021 Ducati Streetfighter V4 S Features
The Fight Formula in Black
The new Dark Stealth color scheme which makes the look of the bike even more thrilling.
Dark Stealth is electrifying, trendy, aggressive, the perfect color scheme to flaunt the “badass” side of the Streetfighter V4 S and attract attention when riding it.
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 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 characterizes 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 color scheme with the double red area with the black extractor in the center emphasises the dynamic look of the bike when viewed from the side.
Fast, agile mixed-road performance demands maximum stability at high speed and when braking, reduced wheel-up during acceleration and minimized 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 maximize the anti wheel-up effect.
The arrival of the 2021 Streetfigher V4 keeps the maximum power and torque values.
The Streetfighter V4 delivers 208 HP (153 kW) at 13,000 rpm and a torque of 122.5 Kgm (123 Nm) at 9,500 rpm. 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.
The rear bank manifolds have been shortened by 100 mm and reduced in diameter from Ø 42 mm to Ø 38 mm. The new component has allowed the introduction of a more compact rear heat shield integrated in the body of the motorcycle.
Also, the introduction of 4 lambda sensors, one for each cylinder, which allow a more refined control of the quantity of fuel injected.
Chassis and 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.
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 personalize 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.
Second-generation TFT instrumentation
The Streetfighter V4 features the same 5″ full-TFT high resolution color screen (186.59 PPI – 800xRGBx480) as the Panigale V4. The dashboard is dominated by the round virtual rev counter on the right. Desmosedici Stradale revs are displayed on a needle gauge.
Movement of the latter is accompanied by a white trail that acts as a ‘shift light’, changing color from white to orange and then red as the rev limit approaches.
The rider can call up two different lay-outs: ‘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.
Accessories and apparel
Complete titanium exhaust assembly
Made exclusively by Akrapovič with the Ducati experience. It is the most advanced racing assembly available on the market.
Each section of the system is manufactured in a special titanium alloy that is both lightweight and resistant to high temperatures, allowing for an overall reduction in the bike’s weight. Once installed on the bike, the exhaust dramatically increases the already excellent weight-topower ratio of the Panigale, for breathtaking accelerations and stretches.
Thanks to its experience in the races has developed the qualities of the motorcycle and exhaust to their maximum levels to create a perfect synergy, specifically for this exhaust, recalibrating the many and fundamental electronic aids: DTC, DWC, DPL and Slide on demand.
