2026 Ducati Streetfighter V4 And V4 S First Look: The Ultimate Hyper-Naked Machine

The Ducati Streetfighter V4 takes one of the simplest recipes in Ducati’s playbook and pushes it closer to the source material than ever before. It remains, in essence, the Panigale V4 superbike stripped of its fairings and fitted with a standard handlebar, but the latest generation now shares its engine configuration, chassis architecture, and much of its electronics package directly with Ducati’s current flagship superbike.

The Streetfighter V4 sits above the 120-horsepower Streetfighter V2 as Ducati’s full-bore naked flagship. Both the V4 and V4 S produce 205 horsepower in the North American market, with the standard bike priced at $24,995. The Streetfighter V4 S starts at $30,995 in Ducati Red, while the Corse version is listed at $32,995. The distinction between the two primarily comes down to suspension, wheels, and weight rather than outright engine performance.

The Panigale Connection Is Stronger Than Ever

The centerpiece remains Ducati’s 1,103cc Desmosedici Stradale engine, a 90-degree V4 with desmodromic valve actuation, a counter-rotating crankshaft, and Ducati’s Twin Pulse firing order. For this generation, however, Ducati says the Streetfighter uses the engine in the same basic configuration as the Panigale V4 for the first time. The difference in peak output comes primarily from the Streetfighter’s intake arrangement.

Output stands at 205 horsepower at 12,650 rpm and 88.3 lb-ft of torque at 11,500 rpm here in the United States. However, European markets will see a slightly more potent 214 horsepower at 13,500 rpm and 88.5 lb-ft of torque at 11,250 rpm out of the SF V4s on their showroom floors. Changes from the previous Streetfighter include revised cam profiles with increased valve lift and, for the first time on the model, variable-length intake trumpets. These switch between 25 mm and 80 mm configurations depending on operating conditions. The alternator and oil pump also come from the Panigale V4 R, while the gear drum traces its lineage to the Superleggera V4.

Power reaches the rear wheel through a six-speed transmission with a standard bidirectional quickshifter and a hydraulically controlled slipper and self-servo wet multiplate clutch. Ducati also raised the engine’s compression ratio to 14.0:1.

A New Chassis Moves It Even Closer To The Superbike

The bigger change arguably sits around the engine. The Streetfighter V4 adopts the latest Panigale V4’s redesigned aluminum Front Frame and hollow symmetrical double-sided swingarm, replacing the previous model’s single-sided setup. Ducati says the frame weighs 7.5 pounds versus 9.7 pounds previously while carrying 40 percent less lateral stiffness, with the aim of allowing more controlled chassis flex at high lean angles.

The new conventional swingarm similarly reduces lateral stiffness by 43 percent compared with the previous design, while Ducati claims the swingarm and forged rear-wheel assembly together save 6 pounds. Steering geometry also changes, with the steering angle increasing by 0.5 degree and trail growing by 1 mm. The resulting figures are a 24.5-degree rake, 3.9 inches of trail, and a 59-inch wheelbase. The bike carries 4.9 inches of front and 5.1 inches of rear suspension travel, with a 33.3-inch seat height and 4.2-gallon fuel tank. The standard Streetfighter V4 weighs 421 pounds wet without fuel, while the V4 S drops that figure to 417 pounds.

Would-be owners will find the largest mechanical distinction in the suspension. The regular Streetfighter V4 uses a fully adjustable 43 mm Showa Big Piston Fork and a fully adjustable Sachs rear shock, along with a Sachs steering damper and cast-aluminum wheels.

The Streetfighter V4 S moves to electronically controlled Öhlins hardware, pairing a 43 mm NIX30 fork with a TTX36 rear shock and electronically adjustable steering damper. The system can alter compression and rebound damping through its event-based control strategy, while Ducati also adds forged aluminum wheels and a lithium-ion battery. Those changes account for the S model’s four-pound weight advantage.

Both versions wear Pirelli Diablo Rosso IV Corsa tires in 120/70 ZR17 front and 200/60 ZR17 rear sizes. Braking hardware is shared as well, with twin 330 mm front discs and radially mounted four-piston Brembo Hypure monobloc calipers. A 245 mm disc and two-piston caliper handle braking duties at the rear.

Superbike Electronics Without The Fairings

A six-axis inertial measurement unit (IMU) anchors the electronics package and supports lean-sensitive braking and the Streetfighter’s broader suite of rider aids. These include traction control, wheelie control, slide control, launch control, engine-brake management, selectable power modes, and four riding modes covering Race, Sport, Road, and Wet settings.

The latest generation also introduces Ducati’s Vehicle Observer system, which uses sensor data and calculated vehicle parameters to refine the intervention of several rider aids. The electronically combined braking system can also apply and modulate the rear brake even when the rider operates only the front lever, depending on the selected settings and riding conditions.

Information is presented through a 6.9-inch TFT display with a 1,280-by-480-pixel resolution and an unusually wide 8:3 aspect ratio. Full LED lighting, pit-lane speed limiting, self-canceling indicators, and dedicated adjustment buttons are standard.

Ducati’s Naked Flagship Is Pretty Much A Panigale With Handlebars

At $24,995, the Streetfighter V4 represents a major step above the $15,995 Streetfighter V2, not simply in output but in the amount of Panigale-derived hardware underneath it. The $30,995 V4 S then adds semi-active Öhlins suspension, forged wheels, a lithium-ion battery, and a modest reduction in weight without changing the engine’s 205-horsepower output.

That positions both models squarely at the extreme end of the super-naked segment. The standard V4 retains the core engine, chassis, brakes, aerodynamics, and electronics of the S, while the more expensive model concentrates its premium on chassis adjustment and lighter components. Either way, Ducati has narrowed the technical gap between its naked flagship and its Panigale V4 superbike to the point where the lack of bodywork is becoming one of the biggest differences left.
