Racing derived aerodynamics

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.

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.
