More comfort, more control

Chassis and ergonomics

Compared to the Panigale V4, the riding position - with an above-ground height of 845 mm - has been redefined as per the specifications of a naked model. In keeping with streetfighter culture, the semi-handlebars have been replaced by a high, wide bar that, together with a seat with 60 mm of foam thickness and moderated footpeg position, ensures sports-style comfort during inner city rides and the control needed to tackle country roads or racetracks.

While maintaining many of the Panigale's stylistic features, the tail is supported by a steel subframe and has been redesigned to enhance passenger comfort and give the rider more lengthways space. 

Front Frame

The Streetfighter V4 features the Front-Frame - an offshoot of Ducati's extensive experience in MotoGP - which uses the Desmosedici Stradale engine as a load-bearing member.

Compared to traditional perimeter frames the main lay-out difference is that the engine is used as a structural chassis element. Weighing just 8.8 lbs, the compact Front-Frame is attached directly to the upper crankcase of the front cylinder bank and the cylinder head of the rear bank; the V4 crankcase also provides the rear suspension attachment point and the single-sided swingarm pivot mount.

The key advantage of the Ducati Front-Frame is that it uses the Desmosedici Stradale engine to achieve the desired stiffness: this has resulted in significantly lower main frame length and weight and a better stiffness/weight ratio. Moreover, the struts alongside the engine have been shortened, making bike design more compact, especially in the rider's seat area.

Completing the chassis is the under-seat Trellis subframe, attached to the Front-Frame at the top and bolted to the head of the rear cylinder bank below.

The rear suspension linkage mechanism is attached to the Desmosedici Stradale engine via a forged aluminium bracket. The linkage reacts to movements imparted by a cast aluminium high-truss swingarm.

Steering geometry features a 24.5° rake and 100 mm trail.

Sophisticated suspension

The Streetfighter V4 mounts 43 mm Showa Big Piston Forks (BPF) to provide full adjustability in spring pre-load and compression and rebound damping. 

The fork bodies house chrome sliders with Brembo radial caliper mountings. A Sachs steering damper completes the front-end package. At the rear there is a fully adjustable Sachs shock absorber, one side of which is attached to the Desmosedici Stradale engine via a forged aluminum bracket.

The Streetfighter V4 S, instead, is equipped with an Öhlins NIX-30 fork, an Öhlins TTX36 rear shock absorber and an Öhlins event-based steering damper. On this version suspension and steering damper are controlled by the second-generation Öhlins Smart EC 2.0 system which, among other things, features the new OBTi (Objective Based Tuning Interface).

Wheels and tires

While the Streetfighter V4 mounts cast aluminum 5-spoke wheels, the V4 S is equipped with 3-spoke Marchesini forged aluminum alloy wheels.

The rims mount Pirelli Diablo Rosso Corsa II tires. Combining track performance with road versatility, they come in the 120/70 ZR17 (front) and 200/60 ZR 17 (rear) sizes, already used extensively for slick tires in the FIM Superbike World Championship. 

The rear tire compound has been designed by Pirelli specifically for the Streetfighter V4. It ensures the same dynamic behaviour as the Supercorsa SP race replica tires mounted on the Panigale V4, but has better low temperature performance to ensure the versatility one expects from a naked.

Braking system with Brembo Stylema® calipers

The StreetFighter V4 range incorporates the powerful Brembo Stylema® monobloc calipers that represent the evolution of the already high performance M50 callipers.

Brembo double calipers have four 30 mm diameter pistons each and work on 330 mm diameter discs for an unparalleled braking power. Whilst the rear system incorporates a single 245 mm disc with a 2-piston calliper. The braking system is supported by the ABS Cornering EVO system, which uses the lightweight 9.1MP control unit.

With the MY2021, new front brake pumps and a self-purging clutch have also been introduced, both originating from those used for the first time on the Superleggera V4. The new pump unit has been designed with a unique configuration to allow “natural” purging, hence eliminating the need to intervene on the system if any air gets into the circuit.

Racing tank

As on racing bikes, the 16-litre aluminum tank has a section that extends under the seat. Compared to the Panigale V4, the lower section of the tank has been modified to allow installation of a seat with thicker padding to boost rider comfort. 

Up front, the space not occupied by fuel has been used to house all the electronics, battery included.

Let’s get down to details

There are a multitude of engineering and technological aspects conceived for this champion road bike. A balance of distinctive lines, brutal output, state-of-the-art technology and components have been combined in this “Fight Formula” of the Streetfighter V4.
