Aprilia has revealed a significant aerodynamic development on its RS-GP26 during the latest MotoGP test in Buriram, underlining the Italian manufacturer’s determination to push technical boundaries ahead of the new season.
The most striking innovation was a previously unseen duct system integrated into the fairing. Positioned to draw air from beneath the bodywork, the dual-sided opening channels airflow through a completely new route. The concept replaces the earlier Formula 1-inspired S-duct, which transferred air from the lower fairing to the upper section to manage turbulence.
This latest solution reflects Aprilia’s continued focus on aerodynamic refinement during the final year of the current 1000cc engine regulations. The project has been led by technical director Fabiano Sterlacchini and head of vehicle department Marco De Luca, with development supported by extensive CFD analysis and wind tunnel testing at Toyota’s facility in Cologne.
From a technical perspective, the twin-duct design is expected to deliver two key advantages. The first relates to aerodynamic efficiency, particularly in reducing turbulence in the lower fairing area. Cleaner airflow in this region may also enhance cooling performance by improving the management of air around critical components.

The second potential benefit is rider comfort. The redirected airflow could help shield the rider’s forearms from the intense heat generated by the engine and radiators. Over race distance, this marginal gain may contribute to improved physical endurance and consistency.
Development has not been limited to the front fairing. The RS-GP26 has also featured a partially-faired rear swingarm, first seen during testing at Sepang. The carbon-profiled component extends downward and incorporates a micro Venturi duct intended to accelerate airflow. Meanwhile, the distinctive “Panoramix” and “Obelix” tail configurations remain under evaluation as Aprilia continues to assess multiple aerodynamic packages.
With the 850cc regulations set to arrive in 2027, Aprilia’s aggressive development programme signals a long-term strategy. The RS-GP26 represents not only an attempt to maximise performance under the current rules but also an investment in aerodynamic knowledge that could shape the brand’s future competitiveness.
As rivals analyse the data from Buriram, Aprilia has made one thing clear: innovation remains central to its pursuit of success at the front of the MotoGP grid.
