Race Performance Closed Cell Foil Kite



At FLYSURFER Kiteboarding—racing is a proving ground for kiteboarding technology—the dedication to the kite-racing sport isn’t just for show. It’s a science. Pushing the SONIC Race to the limit reflects the spirit of the brand, and all of 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 a great racing team and in research and development of our highest performance wing. FLYSURFER SONIC Race developer Benni Boelli supports our athletes during the pro tour season to continuously improve the product. You benefit directly from years of great team work and our absolute passion for hydrofoil racing.

The SONIC Race lightweight construction is built upon our new X-Light fabric for maximum durability and highest stability. Our 3-Level Bridle Design and a total rework of the airfoil greatly improves the aerodynamic efficiency; which results in stunning speeds with improved angles on all courses, and even better—almost unreal—lightwind abilities. Designed on short flying lines and supported by rigid construction and a new mixer which provides reliably-quick manouvering of the wing, the SONIC Race shows its strength in gusty winds and let you fully focus on your riding to win the toughest races.

With the SONIC Race it shows instantly that we made no compromises on performance, get excited by exceptional efficiency – the race is on!

Choose the SONIC RACE in sizes 7m. 9m, 11m, 13m, 15m, 18m or 21m together with the optional Infinity 3.0 Race-Bar Pro and line lengths of your choosing.


The technical features are the result of years of development experience and cooperation with the workshop.

X-Light Fabric
At FLYSURFER Kiteboarding, we made weight reduction one of the important development goals for the SONIC Race. The new X-Light Fabric has the best qualities for maximum performance and impressive longevity. The incredibly lightweight (32g / m²) double-ripstop material is highly tear-resistant as well as airtight, and provides an extremely smooth sail. The X-Light cloth underlines our philosophy of sustainability. You can trust the X-Light Fabric – built into your SONIC Race – to help you reach your best performance every season.

3-Level Bridle Design (A, B, Z)
The next generation in race-kite development. The 3-level bridle design dramatically reduces the number of lines and the associated resistance by an incredible 30{7f1bfda37e37d6699d3cebb5c1d5aed7971856e0deac40555cf8ace0362828e5}. The fully-spliced, uncoated Dyneema SK99 lines are the perfect choice for this application. The result: the best angles at maximum speed on every course. The SONIC Race cuts cleanly through the air.

Modern Competition Technology
Our FLYSURFER Kiteboarding athletes worked hard with R&D race specialist Benni Bölli on fine tuning the prototypes. The SONIC Race is built using the shortest flying lines (from 12-17m, depending on the size), to allow for the fastest manoeuvres and kiting at the lowest angles.

The highlight is the mixer, which can be adjusted by means of a new splice system. Due to the high aspect ratio of the kite, it is difficult to uniformly adjust the angle of attack – but the new mixer transfers power to the kite by means of three deflection pulleys – A1 with 8:1, B1 with 4:1 and B2 with 2:1. It is a perfect match for the 3-Level Bridle Design, and changes the ratio evenly from the middle of the kite down to the tips while braking / depowering. This provides uncompromised maximum performance.

High Performance Construction
The SONIC RACE is imbued with our most cutting-edge technologies taken from both the kite and paragliding development. Proven features such as Cordwise Ballooning, Rigid Foil Technology, and Sharp Mini Ribs are integral parts of the design. The heart of the kite is in its lightweight construction: the arc curve on the B-level allows the surface to be supported along the entire span by means of fewer lines while at the same time keeping the load evenly distributed. The X-Light fabric makes the construction stiffer and allows for an incredible maximum speed with full control in the most difficult conditions. The SONIC RACE is not covered by our 12-Month Free-Repair Warranty.

IKA registered
Take part in every official IKA – Formula Kite race event. We have registered the SONIC RACE kite for every rider. This means that your FLYSURFER SONIC RACE is already approved for every IKA race and you DO NOT need to apply for an additional IKA plaque ID. This was changed for the 2017 racing season.

Automatic Drainage System
The drainage system is integrated in the entire trailing edge of the kite and terminates with 4cm long openings near the tips. This drainage system allows water and sand to be drained automatically, without affecting the performance of the kite. This feature allows you get back in the race quickly after a crash.
