Ducati Streetfighter V4 S: Raw Power, Zero Sacrifices

Ducati pulled the 2025 Streetfighter V4 S right alongside the Panigale V4. Underneath, you get the identical engine layout as the track weapon—minor intake tweaks account for any output variance—while the frame setup, rear arm, and digital brains come straight off the superbike. Forget watered-down streetfighters. Think of this as a Panigale V4 boasting upright bars, crafted to kick out pure circuit pace alongside pure street thrill without full-fairing hassles.

Opting for the S badge gets you top-shelf gear. It targets riders craving the sharpest, most refined, and sensor-dense iteration of Ducati’s hyper-naked concept—equally ready to shred lap times or slice up backroads.

Desmosedici Stradale V4: Born on the Grid, Stripped for the Street

Tucked into the frame sits the 1,103 cc Desmosedici Stradale 90° V4, ripped directly off Ducati’s MotoGP effort. It packs a reverse-rotating crank, Desmo valve actuation, plus a Twin Pulse firing cadence that barks out an aggressive, race-bred exhaust note.

This year, engineers pushed the powerplant near-identical to Panigale V4 trim by fitting variable intake funnels directly from the flagship racer. That single tweak uncorks a 6 hp jump over the outgoing model, pushing max output to 214 hp while smoothing out throttle response and low-end pull. Shaving off engine mass helps lower dry weight, boosting its power-to-weight ratio to top of its class.

Core motor specs (Global / European trim):

Note: North American tuning sits at 205 hp @ 12,650 rpm with 119.7 Nm @ 11,500 rpm. Bolt on the optional track-only Akrapovič exhaust to release extra grunt.

Öhlins Smart EC 3.0: What Gives the S Its Edge

Suspension sets the V4 S apart from the standard Streetfighter. Standard bikes settle for fully manual Showa BPF forks alongside a Sachs rear shock, but the S steps up to Ducati’s semi-active DES 3.0 setup running state-of-the-art Öhlins Smart EC 3.0 gear.

• Front: Öhlins NIX30 (SV) S-EC 3.0 43 mm upside-down fork with TiN-treated stanchions, featuring electronically adjustable compression and rebound damping with event-based control.

• Rear: Öhlins TTX36 (SV) S-EC 3.0 monoshock, also electronically adjustable in compression and rebound.

• Steering damper: Öhlins electronic steering damper with event-based adjustment managed by the Smart EC 3.0 system.

Because it runs as a semi-active setup, the suspension reads speed, throttle position, lean angle, and braking force instantly. Leveraging Objective-Based Tuning (OBTi), it tweaks damping continuously to keep the chassis pliant over bumps yet rock-solid during hard attacks. Testers rave about it: “The Öhlins system adjusts compression and rebound on the fly via the Objective-Based Tuning Interface… it’s now so damn good, I’d happily go racing with it.” Ducati also gave the Streetfighter a softer initial rear linkage rate than the Panigale, soaking up urban asphalt chatter with ease.

Chassis and Swingarm: Tuned for Feel

Engineers built the bike around an aluminium “Front Frame” engineered with less lateral rigidity than the track-focused Panigale. That extra flex boosts tyre feedback and mid-corner traction. By matching chassis flex to the upright bars and higher body posture, riders can feel tyre grip limits directly and lean hard with total faith.

The biggest chassis update center-stages the new Ducati Hollow Symmetrical Swingarm—ditching the old single-sided arm for a twin-sided alloy setup. Lap times drove this decision, not budget cuts. Dropping 37% off its weight while cutting side-to-side rigidity by 43% gives controlled lateral flex for quicker turn-ins, clearer trail feedback, and massive rear drive. Paired with the S version’s forged rear wheel, the back end sheds 6.4 pounds (2.9 kg) compared to its predecessor. Combined with frame weight savings, wet mass stands at 189 kg without fuel.

Geometrical tweaks suit its wide-bar stance. Adding 0.5 degrees of rake over the superbike delivers calmer steering inputs, while a slightly stretched wheelbase keeps high-speed runs settled with relaxed ergonomics.

Chassis geometry:

Braking: Brembo Hypure Hardware Meets Race eCBS

Up front, 4-piston Brembo Hypure® radial calipers bite down hard on 330 mm semi-floating rotors, backed by a 245 mm disc and twin-piston caliper out back. These next-gen Hypure units pack ferocious initial bite and lever feel that stays fade-free session after session. Riders report they bring “superbike-levels of bite and feel”, boosting circuit confidence exponentially.

Brake management relies on Race eCBS featuring lean-sensitive Cornering support, created in tandem with Bosch. Grab the front lever, and the ECU automatically feeds in rear brake force using five tailored modes. On street runs, this settles the chassis and tightens stopping distances by flattening nose-dive. Out on track, even front-brake-only riders gain chassis stability during heavy trail-braking into tight bends.

Electronics: Ducati Vehicle Observer (DVO) Array

At the center of the electronics lies the Ducati Vehicle Observer (DVO)—a code package crafted by Ducati Corse capable of virtualizing input from 70 virtual sensors and tracking 70 physical parameters to calculate exact traction and wheelie intervention levels. Ported directly from MotoGP tech, this system operates pre-emptively, maintaining total composure and rider trust whether on track or mountain passes.

Riders manage everything through a crisp 6.9-inch TFT screen running a 1280 x 480 layout in an 8:3 format. Thanks to optically bonded glass, glare is practically nonexistent under glaring sun, while dual Display Modes—Road (dominated by an analog-style tach) and Track (highlighting a full bar-graph tach with lap timers)—let you tailor the display instantly.

Aerodynamics: Double-Tier Wings Built In

The Streetfighter V4 S mounts double-tier winglets along its flanks, blending sharp aesthetics with functional downforce. Up to 45 kg (99 lb) of downforce squashes the front tyre at 270 km/h, pasting the front wheel to the tarmac under hard acceleration while steadying high-speed runs. Unleashing all 214 horses on a straightaway feels planted and controllable through the handlebars.

Ergonomics and Design: Improved Comfort, Raw Stance

Styling mixes raw menace with high-end detail: signature LED headlights with DRL lighting, an angled 16-litre aluminium cell, and a tight rear end showing off the V4 and two-sided swingarm. Sharp biplane wings and traditional Ducati Red or Corse livery make its identity clear at first glance.

Ducati overhauled the cockpit layout to make daily riding easier without dulling performance:

• The handlebars sit 10 mm closer, easing arm reach without compromising control.

• The footpegs sit 10 mm narrower, granting extra ground clearance at full lean while letting riders clamp the chassis easily.

• The saddle offers extra width and padding over the Panigale seat, turning this weapon into an all-day road bike.

• The fuel cell features deep side cutouts, letting knees lock firmly under heavy braking.

Journalists love the relaxed, roomy ergonomics, pointing out how well it fits taller riders. Toggling riding modes lets the bike switch from a relaxed commuter into a surgical track missile in a heartbeat.

Colour options:

• Ducati Red (standard)

• Corse Livery—inspired by the Desmosedici GP 2025, combining traditional Ducati red with fluorescent accents and a white number plate area.

V4 S vs. Standard V4: Upgrade Breakdown

The S package brings premium hardware that elevates the whole riding experience:

Merging semi-active Öhlins dampers, forged alloy rims, and a lithium battery endows the V4 S with effortless tipping effort, lower rotating mass, and sublime suspension action on any pavement surface. Hands down, it stands as the ultimate, most uncompromising take on the Streetfighter blueprint.

Technical Specifications

Raw horsepower alone doesn’t make the Ducati Streetfighter V4 S king of its segment; sheer perfection in execution does. Öhlins Smart EC 3.0 semi-active suspension pairs up with lightweight forged rims, a tiny lithium battery, and full-bore Ducati Corse race-grade electronics. The result? Pure telepathic handling. Every input feels immediate, crisp, utterly dialed in. Take it to a circuit, and you’re riding a true superbike minus the clip-ons. Slice through daily traffic, and it plays nice—until you crack the throttle open and unleash mayhem. That’s the Fight Formula perfected.
