SONIC2... ride leading technology


A proving ground for FLYSURFER Kiteboarding technology, the dedication to the kite-racing sport isn't just for show. It's a science. The racetrack has repeatedly been a laboratory for successful development of our products and innovations. Pushing the SONIC2 to the limit reflects the spirit of the brand and the men and women who strive for victory.


To strengthen our competitiveness and to lay the foundation for the success of our athletes, we are continuously investing in R&D. You benefit from the results of these long-term tests under extreme conditions.


The SONIC2 lightweight construction, includes a LOTUS cloth topsail for an even smoother airflow, as well as our proven DLX+ cloth for more control and responsive turning. The total rework on the airfoil improves the aerodynamic efficiency, which results in stunning speeds with improved angles on all courses. The SONIC2 was also thoroughly tested with twintips and built specifically for extreme jumps with long hang-time to also make it one of the best Big Air products on the market.


The SONIC2's virtue of highest lift to drag ratio instantly shows the exceptional qualities that a foil kite with depower has to offer. Experience the fascinating balance of raw power, mad lift and outstanding hangtime from the get go. Aesthetic high-performance technology.

Double Cordwise Ballooning
Double Cordwise Ballooning minimizes the creasing of the cells on the kite to an absolute minimum. With exactly calculated arc-shaped panel cuts and double-stitched and glued seams, a perfectly smooth, high performance airfoil is created. This optimizes the aerodynamics, especially the glide ratio and the low end of the kite.


Flat Winglet Technology
The Flat Winglet technology reduces the induced aerodynamic drag, whilst at the same time increasing lift. This leads to a noticeable improvement in lift to glide ratio and forward flying speed of the kite. As well as constant pull while turning without wingtip collapse.


Maximum Pressure Valves
The M.P.V in the center of the leading edge provides maximum air flow into the kite. The kite fills faster and accelerates even when fully depowered. A moving separator inside the valve transfers the airflow directly into the kite, regardless of angle of attack. Improved internal pressure means the kite is stiffer, more responsive and stable.

Rigid Foil Technology
These stiffeners integrated in the leading edge ensure a smooth, creaseless and stiff topsail. This results in reduced aerodynamic drag and enhanced kite stability. As a result, the kite translates every gust of wind into propulsion without deforming the canopy. Overall, the Rigid Foils increases the kite’s stiffness and makes it more dynamic.


Lightweight Construction
The SONIC2 benefits from a unique material composition. The LOTUS top sail forms a wrinkle-free airfoil and facilitates the relaunch in light winds. The DLX + bottom sail contributes to the directness of the kite and allows a reactive bar feedback. The ribs, V-belts and cells of the inner construction are designed for diagonal rigidity at highest loads to keep the SONIC2 in form. The weight reduction obtained increases stability and allows deeper downwind courses.


Sharp Mini Ribs
Doubling the number of cells at the trailing edge increases its shape stability substantially. This means less turbulence, improved aerodynamics and thus performance.


IKA registered
FLYSURFER is passionate about kite-racing and has registered the SONIC2 kite officially. This allows you to attend every official IKA racing event. Even if a FLYSURFER kite construction is officially approved for kite racing in the IKA class – Formula Kite, this does NOT mean that the kite itself is automatically IKA registered. This must be registered by the rider him/herself, so that he/she is allowed to officially compete in the IKA class – Formula Kite and its specific events. Link to registration form:


Triple Depower Technology
There are 3 ways the kite achieves its maximum depower: Reducing the angle of attack, profile change and reducing the projected area. This leads to a huge wind range and ideal handling.


Automatic Drainage System

The proven drainage system integrated in the whole trailing edge of the kite, with finally openings near the tips, about the size of a hand. They allow water and sand to be drained automatically, without influencing the performance of the kite.


Uniform Bar Setup

Our Infinity 3.0 Control Bar system is designed to be used on all FLYSURFER kites. It is only necessary to ensure that the stopper knot is set to the longest FLS position of the kite of choice.
