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 In keeping with streetfighter culture, the semi-handlebars have been replaced by a high, wide bar that, together with a seat with 60 mm of foam thikness and moderated footpeg position, ensures sports-style comfort during inner city rides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.
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 aluminium 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 tyres
While the Streetfighter V4 mounts cast aluminium 5-spoke wheels, the V4 S is equipped with 3-spoke Marchesini forged aluminium alloy wheels.
The rims mount Pirelli Diablo Rosso Corsa II tyres. 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 tyres in the FIM Superbike World Championship.
The rear tyre compound has been designed by Pirelli specifically for the Streetfighter V4. It ensures the same dynamic behaviour as the Supercorsa SP race replica tyres 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® callipers
The StreetFighter V4 range incorporates the powerful Brembo Stylema® monobloc callipers that represent the evolution of the already high performance M50 callipers.
Brembo double callipers 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 Bosch Cornering 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.
As on racing bikes, the 16-litre aluminium 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.
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.
