Aerodynamics

To ensure maximum stability both at high speeds and when braking and a lower tendency to wheelie during acceleration, limiting as much as possible the interventions on the chassis so as to have a nimble and quick behaviour in mixed conditions, wings have been developed for the Ducati Streetfighter V4 in biplane configuration designed by Ducati Corse specialists in collaboration with the Centro Stile Ducati.

The aerodynamic development was carried out entirely with CFD (Computational Fluid Dynamics) simulations using a calculation method that involves stationary simulations of the motion and pressure fields with the aim of increasing the vertical force on the vehicle, in particular on the front wheel.

Mudguards

The new fenders provide 35 kg (+ 7 kg) of "downforce" at 270 km/h, including 27 kg on the front wheel and 8 kg on the rear.

Increasing the "anti-squat" effect

Increases the anti-squat action that helps the rider thanks to greater stability, precision and the ability to maintain the trajectory when exiting corners and, in general, in all acceleration situations.

Increased support under braking and cornering

Increased support in haste and cornering is provided by both the new ergonomic shape of the fuel tank and the increase in its capacity (+ 0.5 liters).

Biplane wings by Ducati Corse

To reduce the lateral dimensions of the appendages as much as possible, it was decided to develop an aerodynamic configuration that provides two wings of reduced opening positioned in the shape of a biplane with the aim of making them work independently. The single appendage can be described as a wing with a single element and a rectangular plan, equipped with a winglet on the external lateral end. The wings have been positioned as close as possible to the front wheel (near the side radiator panels) in order to maximize the anti-wheelie effect.

How they work

The vertical load generated by the wings reduces the "buoyancy" of the front wheel at high speeds, the tendency to wheelie and increases stability during braking, entry and cornering.

This dynamic behaviour instils safety and limits the intervention of the electronic controls, so that the rider is led to keep the throttle open for longer as well as to brake later right into the corner, benefitting in terms of performance.

What are the benefits

The effect of the introduction of the aerodynamic appendages is 28 kg of downforce at 270 km / h, of which 20 kg on the front wheel and 8 kg on the rear wheel. The wings also give benefits in terms of heat loss by increasing the speed of passage through the water and oil radiators, respectively by + 2% and + 10%.
