New Ducati Streetfighter V4: the highest performing Fight Formula ever

For the first time, the Streetfighter V4 mounts the Desmosedici Stradale engine in the same configuration as the Panigale V4.

The new Streetfighter V4 is at the top of its performance class, with a power-to-weight ratio of .49 hp/lb

MotoGP-derived technology combines fun on the road with Superbike performance on the track like never before

Electronics and chassis are derived directly from the 2025 Panigale V4, with aerodynamics integrated into the style of the bike and the new Hollow Symmetrical Swingarm

The 2025 Ducati Streetfighter V4 and V4 S are bikes born from the application of Fight Formula on the new Panigale V4 – the seventh revolutionary generation of Ducati superbikes – and sit at the top of their performance class while improving rider comfort and enjoyability in road use.

The new Streetfighter V4 is a beautiful, fast, and sophisticated Ducati superbike, stripped of its fairings, with a high and wide handlebar, a weight of 417 lb., a 205 hp Desmosedici Stradale engine, biplane wings, and an electronics package that is unlike any other in the world.

Derived from the Panigale V4, it consists of the same engine, chassis, and electronics configurations. The difference in horsepower is due to different intakes. For the first time, Ducati has chosen to transfer the technology and performance of the Panigale V4 to a naked bike without sparing anything, creating a bike that combines the best of both worlds—track handling like a supersport bike and road enjoyment like a true naked.

Its impressive power/weight ratio of 0.49 hp/lb. obtained from a lighter engine combined with electronic and chassis developments such as DVO, Öhlins Smart EC3.0 suspension, and the new Race eCBS braking system makes the Streetfighter V4 even more effective on the track.

At the same time, it can be fun on the road with superior comfort in everyday riding. This is thanks to the wider calibration range guaranteed by the suspensions to a more rigorous chassis that gives the rider a greater feeling and ease of riding with a more contained exhaust noise while simultaneously offering great character to the bike.

Desmosedici Stradale engine

The Streetfighter V4 engine derives from the Panigale V4, with an even more direct link than the previous model. The Desmosedici Stradale is closely derived from the Ducati MotoGP bikes, which share numerous technical solutions, starting with the architecture. It is a 90° V4 with desmodromic distribution, counter-rotating crankshaft, and Twin Pulse timing, which gives the Streetfighter V4 a sound similar to that of the Desmosedici GP.

The Desmosedici Stradale of the new Streetfighter V4 has had its distribution diagram revised compared to the version of the previous model, with cams with a different profile and a higher lift value. The alternator and oil pump are the same as those mounted on the Panigale V4 R, while the gear drum is used on the Superleggera V4. For the first time, the Streetfighter V4 also features variable-length intake trumpets, with a value of 25 mm in the short configuration and 80 mm in the long one, thus simultaneously increasing maximum power and rideability.

The Desmosedici Stradale engine delivers 205 hp at 12,650 rpm and a maximum torque of 88.3 lb.-ft at 11,500 rpm. Values ​​that can be higher in track configuration: by adopting the Ducati Performance by Akrapovič racing exhaust, the maximum power increases to 226 hp. The Streetfighter V4 has never been so powerful.

Design

The design of the new Streetfighter V4 maintains the unmistakable Streetfighter DNA, and its Panigale nature is stripped of the fairing. With more balanced proportions and distribution of volumes between the front and rear, the Streetfighter V4 has lines aimed at the front that make the bike look ready to launch toward the next bend. A completely new full-LED headlight enhances the aggressive face of the new Streetfighter, maintaining its iconic light signature. At the rear, the full LED light cluster is functionally divided into two parts, generating that double C that characterizes the sportiest Ducatis.

The 4.2-gallon tank, particularly narrow in fit and characterized by a distinct shoulder, is reflected in the tail, which is more elongated towards the rear, with a shorter license plate holder and the passenger seat positioned lower than the 2024 Streetfighter V4. Both components have been designed to combine style and functionality, improving ergonomics while riding.

Finally, the forward-slanting biplane wings, a distinctive element of the Streetfighter V4 since its inception, remain a key distinct element of the motorcycle. Compared to the previous model, they are more effective (+99 lb. of downforce at 167 mph) and integrated more into the design line. The wings allow for a bike with very nimble chassis qualities but, at the same time, stability and rigorousness at high speeds. Finally, the exhaust under the engine maintains the stylistic imprint of Ducati sportbikes, keeping the center of gravity low and leaving a clear view of the new double-sided Hollow Symmetrical Swingarm, also visually lightened by the large exhaust openings on both sides.

Ergonomics

The riding position of the new Streetfighter V4 is derived from that of the Panigale V4. Still, it has been designed to improve vehicle control and increase comfort, especially for taller riders. The seat-tank unit offers more freedom of longitudinal movement thanks to greater room, making reaching and maintaining the aerodynamic posture more natural. A deep recess in the upper part avoids interference with the helmet chin guard.

At the same time, the rear area of ​​the tank, combined with the side covers and the seat shape, increases support for the rider during braking, corner entry, and cornering. The rider will find it easier to anchor himself with his knees to counteract deceleration and lean out of the saddle once the bike is in a curve, thus reducing the effort on the arms and, therefore, fatigue.

Compared to the previous Streetfighter V4, the bend of the handlebar has been moved back, now closer to the rider by 10 mm, and the footpegs are lower and more forward and positioned 10 mm further inward. This increases comfort for the rider without compromising ground clearance. Finally, the two vents inside the side panels move hot air away from the rider’s legs, improving thermal comfort.

MotoGP-derived chassis
Thanks to the very rigorous chassis of the new Panigale V4, it was not necessary to lengthen the swingarm to stabilize the bike with the new Streetfighter V4. Still, improving the front chassis dimensions (+0.5° steering angle, +1 mm on the trail) was sufficient to find the synthesis between agility and stability.

Just like the new Panigale, the chassis of the Streetfighter V4 is entirely new. The Front Frame is, therefore, lighter (7.5 lb. compared to the previous 9.7) and reduces stiffness compared to the previous model (-40% in lateral) to offer improved confidence when leaning in taking the apex and maintaining the trajectory.

Furthermore, the double-sided Ducati Hollow Symmetrical Swingarm improves traction when exiting corners and the rider’s feeling in acceleration, with a reduction in lateral stiffness (-43% compared to the single-sided swingarm of the previous model) and an overall lightening of the swingarm-forged rear wheel assembly equal to 6 lb. On the Streetfighter V4 S, the forged aluminum alloy wheels with five tangential spokes, inspired by those of the DesmosediciGP, weigh only 6.5 and 10 lb., respectively, for the front and rear.

The third-generation electronically controlled Öhlins NIX/TTX suspension of the Streetfighter V4 S expands its adjustment spectrum, allowing more comfortable calibrations for road use and more sustained and effective when riding between the kerbs of a circuit. At the same time, the increased speed of the hydraulic valves offers a more precise and accurate response in every riding situation. Furthermore, compared to the Panigale V4, the rear suspension link is more progressive to provide greater comfort on the road, which is increased thanks to “Cruise Detection.” The latter softens the suspension when it detects a constant pace, such as on motorway transfers, significantly increasing rider comfort.

Like the new Ducati Panigale V4, the Streetfighter V4 also mounts Brembo Hypure™ front brake calipers. Lighter (-2 ounces per pair compared to the Stylema of the previous model) and higher performing, the Brembo Hypure™ calipers disperse the heat generated by braking more effectively, offering more consistent performance for riders seeking their limits.

The Race eCBS system with Cornering functionality, developed by Ducati in collaboration with Bosch, can activate and modulate the rear brake, limiting load transfers and improving the stability of the bike in the braking phase both in road and track use, even when the rider only applies the front brake. The system, which offers five levels against the three of the previous Streetfighter model, intervenes similarly to what is done by professional riders at the lowest levels, reserved for track use, while improving safety and stability at the higher levels, designed for road use.

Ducati Vehicle Observer

The Ducati Vehicle Observer, an algorithm developed by Ducati Corse in MotoGP, simulates the input of over 70 sensors, thus refining the electronic control strategies, which can achieve unprecedented effectiveness in series production. The precision of this functionality allows the controls to intervene in an almost predictive way to promptly accommodate the rider’s needs in the search for maximum performance.

The 2025 Streetfighter V4 has a complete package of electronic controls: Ducati Traction Control DVO, Ducati Slide Control, Ducati Wheelie Control DVO, Ducati Power Launch DVO, Engine Brake Control and Ducati Quick Shift 2.0. The DQS 2.0 system uses a strategy based solely on the gear drum angular position sensor, thus being able to use a gearshift rod without microswitches and therefore offering the rider a more direct feeling with reduced travel.

New 8:3 dashboard

The new 6.9” dashboard with 8:3 “aspect ratio” offers maximum readability. The protective glass uses Optical Bonding technology to provide optimal readability on a black background, even during the day. The interface offers differentiated views (Infomode) for use on the road or the track to support the rider in the search for maximum performance in the second in either environment.

The dashboard dynamically changes its layout, moving the columns and redistributing the spaces to offer maximum visibility to the functions that are being used at the moment, such as the navigator. Similarly, by selecting the Views mode, the left column gains space by moving the rev counter to the right and compressing the right column to display the different functions available, including the TPMS, instantaneous torque and power delivered, lateral and longitudinal acceleration values, instantaneous lean angles and action on the throttle and brake.

The Road Infomode has very clean graphics, emphasizing the round rev counter placed in the center and indicating the engaged gear inside. The left side of the screen is reserved for the settings, the navigator, if installed, the music player, the management of the smartphone and accessory heated grips, and the different functions available for each of these features. On the right side are the indications of speed, time, water temperature, and cruise control, if enabled.

The Track mode, combined by default with the Race Riding Mode, is designed to emphasize the most relevant information in circuit riding. The rev counter is positioned at the top of the screen, with a scale compressed up to 9,000 rpm. At the same time, in the center, the rider finds the indication of the gear engaged, and on the right, the levels are set for the electronic controls (adjustable via the right rocker) and their activation. In the left column, we find the stopwatch, which, by mounting the DDL accessory or via the GPS module, can show lap time with different split times, lap number, and the indication of the improvement in absolute terms or about the session using the same color codes – white, grey, orange, red – used in MotoGP.

The new Streetfighter V4, available in V4 and V4 S versions, featuring Öhlins suspension and steering damper, forged rims, and lithium battery, will arrive at dealerships in the United States in April 2025. Pricing for the Streetfighter V4 will be $23,395 and $29,295 for the V4 S model in the United States. Both are offered in single-seater configuration, with a passenger kit available as an accessory.
