2025 Ducati Streetfighter V4 and V4 S – First Look

The Ducati Streetfighter V4 has never been a slouch in the performance department, but until now, it was never quite on par with the Panigale V4, using a different tuning for its Desmosedici Stradale engine and having some differences to their chassis and electronics. With a new, seventh-generation Panigale V4 introduced for 2025, Ducati has narrowed the difference, bringing the Streetfighter V4 closer than ever to the Pani and making it a true naked superbike.

The only difference is to the design of the air intake, resulting in a 2 hp difference between the naked bike and the sportbike. For Euro5+ models, Ducati claims a peak output of 214 hp at 13,500 rpm and 88.5 lb-ft. at 11,250 rpm for the Streetfighter V4, but as was the case with the Panigale V4, North American models have different figures, with Ducati claiming 205 hp at 12,650 rpm and 88.3 lb-ft. at 11,500 rpm. An accessory track-only Akrapovič racing exhaust pushes the power even further, with Ducati claiming a peak of 226 hp.

The chassis is derived from the new Panigale, with a lighter front frame with reduced lateral stiffness. The Streetfighter V4 also adopts the new double-sided Ducati Hollow Symmetrical Swingarm. Ducati claims it provides improved traction, less lateral stiffness, and less weight than the previous design, though there is a sizeable following who will mourn the loss of the single-sided swingarm.

The Streetfighter V4 S will come equipped with Öhlins Smart EC 3.0 event-based electronic suspension, with an NIX30 43mm fork and TTX36 shock, both fully-adjustable. The base model Streetfighter V4 makes do with a 43mm Showa BPF fork and Sachs shock, both also fully-adjustable.

Both versions come equipped with dual Brembo Monoblock Hypure radially-mounted four-piston calipers and 330mm front brakes, plus a 245mm disc and two-piston caliper rear brake. The lean-sensitive Race eCBS that debuted on the Panigale V4 comes standard. The system automatically modulates the rear brake to provide stability, even when the rider applies just the front brake.

Other standard electronic aids include four selectable ride modes, lean-sensitive traction control, slide control, wheelie control, engine brake control, launch control, and the bi-directional Ducati Quick Shift 2.0 system. A new 6.9-inch screen with an 8:3 aspect ratio displays the Streetfighter V4’s data and electronic settings. Most of these functions make use of the Ducati Vehicle Observer, an algorithm developed by Ducati’s MotoGP program to simulate the input of over 70 sensors.

Visually, the Streetfighter V4 retains elements of previous versions, while offering a better visual balance between the front and rear than the 2023 model. The 4.2-gallon fuel tank has a flatter top than the old design, and has a new shape to make it easier for riders to anchor their knees when decelerating or leaning into a curve.

Ducati moved the handlebars back 10mm while repositioning the footpegs lower, further forward, and 10mm further inward, claiming improved comfort without sacrificing ground clearance.
