Back

The Panigale V4, stripped of its fairings and with high, wide handlebars. This, in short, is the underlying concept of the new Streetfighter V4, a bike that magnifies the thrill of the ride every time it takes to the road.

The result? An unrivalled naked bristling with cutting-edge technology and an awe-inspiring design that oozes pure performance.

The minimalist full-LED headlight captures the spirit of the Streetfighter V4 perfectly. On the one hand, it recalls the front of the Panigale V4 and, on the other, evokes the crazy grin of the Joker (the comic strip character from which the Ducati Style Center drew inspiration for this new Bologna-built naked). Already featured on the Panigale V4 and SuperSport, the V-shaped DRL is another clear Ducati hallmark.

Joker face

The minimalist full-LED headlight captures the spirit of the Streetfighter V4 perfectly. On the one hand, it recalls the front of the Panigale V4 and, on the other, evokes the crazy grin of the Joker (the comic strip character from which the Ducati Style Center drew inspiration for this new Bologna-built naked). 

Already featured on the Panigale V4 and SuperSport, the V-shaped DRL is another clear Ducati hallmark.

The compact headlight is embedded in a meticulously designed dual-layer fairing that incorporates the air-box and LED cooling intakes; a rear deflector, instead, stops flows impacting the tank directly. 

The headlight is surmounted by a 5" TFT screen (the same as the one on the Panigale V4) and features a smartly styled front cover that hides connectors and wiring.

The magic of Aerodynamics

Fast, agile mixed-road performance demands maximum stability at high speed and when braking, reduced wheel-up during acceleration and minimised electronic control of the suspension set-up: that's why Ducati Corse specialists have, together with the Ducati Style Centre, developed biplane wings for the Streetfighter V4.

The aerodynamics were developed using CFD (Computational Fluid Dynamics) simulation. The calculation method involved stationary simulation of flow and pressure to achieve increased downforce, especially on the front wheel.

To reduce lateral protrusion as much as possible, the aerodynamics team decided to adopt a 'biplane' configuration of limited 'wingspan' with upper and lower wings working independently. 

Each appendage can be described as a square-plan mono-wing with a winglet on its outer tip. Moreover, the wings have been positioned as close as possible to the front wheel (near the radiator side panels) to maximise the anti wheel-up effect.

These aerodynamic appendages generate 28 kg of downforce at 270 kph (20 kg on the front wheel, 8 kg on the rear). The wings also help draw heat off the engine by increasing water and oil radiator throughflow speeds by 2% and 10% respectively.

Wing-generated downforce attenuates front wheel 'floating' at high speed and the tendency to wheel-up. It also improves stability during braking at the turn-in point and through the corner.

The aerodynamics thus instil confidence and limit intervention by electronic controls. This helps the rider keep the throttle open longer and brake later going into the bends, providing significant performance benefits.

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 4 kg, 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.

High Power

The new Streetfighter V4 is powered by a 1103 cm3 Desmosedici Stradale engine. In this configuration the 90° V4 delivers 208 hp (153 kW) at 12,750 rpm, an unrivalled power level within the naked segment, perfectly in keeping with the all-out character of the new Streetfighter V4. Maximum torque is 123 Nm (12.5 kgm) at 11,500 rpm, practically unchanged with respect to the Panigale V4. Dedicated engine mapping lets riders safely make the most of Streetfighter V4 performance on the road.

The final ratio, shorter than that of the Panigale V4, delivers a wheel torque higher of +10%, which ensures an immediate response to the throttle command.

Power and torque can be raised to 220 hp (162 kW) and 130 Nm (13.2 kgm) by fitting the full-racing Ducati Performance exhaust by Akrapovič that also reduces weight by – 6 kg.

MotoGP-derived engine

The Desmosedici Stradale was designed around the core of the V4 MotoGP engine – the cylinder heads. With the same dimensions and geometry as the Desmosedici GP, the Desmosedici Stradale offers the same outstanding fluid dynamics. It also has the same engine configuration: 90° V4, rotated rearward by 42°. 

This solution makes the engine extremely compact, allowing centralisation of mass and flawless integration with the vehicle.
