2023 Ducati Streetfighter V4 S – Ducati’s Superbike for the streets. The Streetfighter V4 was an immediate success right from its introduction in 2020, conquering enthusiast hearts and minds better than its V2 predecessor. The renewed 2023 Streetfighter V4 comes in three versions: the basic Streetfighter V4, Streetfighter V4 S, and Streetfighter V4 SP2. All share the major technical upgrades of the 2023 Panigale V4—only natural given the common roots. Basically, the new Streetfighter is a 2023 Panigale V4 stripped of its fairing and fitted with a taller and wider handlebar in place of the clip-ons, along with biplane winglets and Ducati’s latest electronics suite.
The new Streetfighter V4′s styling also has evolved from the previous edition’s, with a new LED headlight and a V-shaped daytime running lamp that make the bike look even more aggressive. The streamlined radiator remains one of the best integrated in motorcycling, and serves as a functional support for the biplane winglets. The Streetfighter shares its fuel tank with the Panigale V4, and is more ergonomically profiled at the knees; its capacity is also increased to 4.5 gallons.
New and very “fast” is the monoposto rider-only seat; removing the aero cowl reveals a passenger section. The seat itself is generously padded (2.4 inches thick) and gives the bike a 33.3-inch seat height.
The chassis is based on the pyramidal sheet-aluminum structure Ducati calls a “front frame.” This uses the engine as an integral stressed chassis member for a very light construction, rigid overall in terms of both flex and torsion. The chassis geometry leans toward the sport segment: 58.6-inch wheelbase, 24.5 degrees of steering rake, and 100mm (3.9 inches) of trail.
Suspension is courtesy of a 43mm male-slider Showa BPF fork and with a gas-charged Sachs shock at the rear. Five-spoke cast-aluminum wheels wear Pirelli Diablo Rosso IV Corsa radials (120/70-17 front, 200/60-17 rear). The tires are common for all three Streetfighter models. As for brakes, the Streetfighter uses twin 330mm Brembo front rotors and Stylema Monoblock calipers, managed by Bosch Cornering ABS EVO.

The Streetfighter V4 S gets the full Öhlins suspension treatment: Its 43mm NIX 30 fork and TTX 36 shock are electronically managed by Öhlins Smart EC 2.0 event-mode software. In addition, it rolls on forged-aluminum three-spoke Marchesini wheels.
Compared to the previous Streetfighter, positioning the swingarm pivot 4mm higher is a very meaningful chassis evolution. This was based on racing experience gathered by Ducati Reparto Corse; the change in swingarm geometry reduces squatting under acceleration and also helps put more load on the front end for more stable and precise steering response.
