The 2026 season has started off on a high for Aprilia racing, with two wins for Marco Bezzecchi and a podium for Jorge Martín at the first two rounds of the year. The Italian team have most definitely placed themselves as a power lead in the aerodynamic development sector, as over the past two years they’ve developed many important devices.
In fact, at the first rounds of the 2026 MotoGP championship, all eyes were set on a specific outstanding innovation: the F-duct.
Before we talk about Aprilia’s innovation, we must take a step back to understand how far aerodynamic developments have come in MotoGP.
Historically speaking, aerodynamics were never a fundamental part of bike development, as the main aim of each team was to create reliable and powerful engines.
The first innovations that saw the light of day were the so-called “dustbin” fairings, which made their way into motorcycle racing around the 1950s.
This very important aerodynamic body work was meant to reduce drag and maximise high-speed stability. Its smooth construction had the purpose of limiting the turbulent air, which would slow the bike down.
Although seemingly perfect, the dustbin fairings were highly unstable in crosswinds, which meant the bike performed poorly when cornering or overtaking.
Efficiency was not the only struggle, the dustbin fairings were all around dangerous when they encountered crosswinds. Therefore, in 1958, the Fédération Internationale de Motocyclisme (FIM) banned the revolutionary aerodynamic bodywork and classified it as a safety hazard.
In the following years, no significant changes were made to the bikes, as the main focus of each team was to develop engines and safety gear.
In the 1980’s, almost 20 years later, we saw the introduction of a new aerodynamic component: the speed hump.
It was initially created as a safety feature for the riders to protect their necks during falls, but promptly became an aerodynamic gem used to this day.
When the riders adopt a crouched position, the air that flows between their helmet and their back becomes turbulent, which ultimately slows them down. The hump was therefore designed to smooth out the airflow and optimise it with the intention of increasing top speed and stability.
With modern MotoGP evolutions, the hump not only remains a part of the aerodynamic components, but it also functions as an electronics storage and hydration system.
The real introduction of specialised aerodynamics began with the arrival of Luigi Dall’Igna at Ducati in November 2013.
By introducing Formula One - inspired engineering, the Italian began to experiment with different innovations, bringing the world of aerodynamics closer to MotoGP.
It was Dall’Igna who first introduced the aero winglets on the Ducati GP16. This key innovation allows stability, generates downforce, increases air resistance and overall makes a significant change to the rider's speed.
In 2019, the Italian pioneered the ride-height device. Another revolutionary technology that allows lowering the centre of gravity of the bike by dipping and locking the rear end. As a consequence, the riders obtain better acceleration and limit wheelies off the start line.
Most of the aerodynamic revolutions are intended to fight the phenomenon of wheelies, as they often occur when a bike suddenly accelerates, causing the front tyre to lift and disrupt the rider.
This system is manually activated by each rider who, alongside their team, carefully selects the right moment to use it, usually on the starting line or before straight acceleration zones.
Although Ducati was the first manufacturer to bring aerodynamic changes, as the years went on, all the teams began to catch up.
As of the last few years, Aprilia have definitely taken on an important part in the aerodynamic developments department.
The Italian team worked with a former Formula One aerodynamicist, Marco de Luca, alongside their technical director, Romano Albesiano, together they designed and introduced ground effect racing in 2022.
Although largely inspired by car racing ground effect, MotoGP’s case is essentially very different.
It’s created by using channelling devices and carefully designed shapes to alter the speed of airflow around the bike.
When the bike is straight up, the airflow is redirected to lower the force of gravity on the front of the bike so that the tyre can successfully grip the asphalt. The overall aim is to maximise the force between the tyre and the ground so that the bike can ride faster on the straights and corners.
Considering that MotoGP bikes lean up to a 60° angle, the ground effect system uses accurately designed fairings to control how much air flows around the vehicle, even at an angle. By doing so, a flow acceleration is created where the pressure brings the bike closer to the ground.
In the 2026 season, Aprilia has introduced a new impressive aerodynamic device. The F-duct is closely inspired by the 2010 device brought by the McLaren Formula One team.
The McLaren took an air feed through the front of the car, redirected it through the cockpit and allowed the driver to turn it off by plugging the vent with his forearm or knee. Eventually, this device was banned by the Fédération Internationale de l’Automobile (FIA) because it was considered dangerous for the driver to move around in the cockpit.
Aprilia’s F-Duct is a vent that redirects the flow of air around the bike. The particularity of this device is that at the end of the vent, an opening is placed, which can be closed by the rider's forearm.
When uncovered, the air circulates through without any kind of alterations, but when the vent is covered, the air is redirected towards the wings on the side, which reduces drag and promotes ground effect.
Aprilia has become the first manufacturer to introduce a form of active aerodynamics. Although not directly classified as active aero, considering the regulatory ban, Aprilia have definitely managed to find a loophole around the rulebook.
It appeared to be completely within the regulations as it’s not a moving mechanical part, like DRS in Formula One, but it’s activated by the driver's movements. It is also not considered a safety issue because the rider is moving around just like in any normal race.
It is safe to say aerodynamic innovations are probably the most fascinating introduction in any kind of motorsport, therefore it’s amusing to finally have some significant developments in MotoGP.
Although at the moment, it’s a very controlled sector, as each team is allowed only one innovation per season. Only time will demonstrate how far developments can go. We are most definitely ready to learn all about them!
