STREAMLINED LIGHTWEIGHT CONSTRUCTION
The combination of lightweight construction, durability and optimal force distribution across the entire span. The upper and lower sails are made of 34 g/m² TX-Light, the leading edge of 44 g/m² DLX+ cloth. The DLX+ increases the service life and protects against abrasion. The Little Connection Lines (LCL) serve as a predetermined breaking point and make it easier to replace the bridle lines. All components of the SONIC are designed for maximum performance in any terrain.
PERFORMANCE TUNER
The Performance Tuner is a knot ladder integrated into the C-Pulley Line to influence the camber of the kite. Moving the Z-Main Line influences the bar forces and performance of the kite. By shortening it you get more low end, steering/holding forces. Lengthening it has the opposite effect, you get less backstall, steering/holding forces. With the settings for brake emphasis, power and depower you can optimize - depending on wind conditions and personal preferences - to exploit the maximum potential of the kite.
Bridle Check Tool
Profile Momentum Adjuster
The SONIC is a trustworthy, user-friendly and predictable powerhouse that you'll want to ride in challenging weather. Specialized to meet the needs of the next generation of big air kiters and loyal foil kiters.
WIDE WIND RANGE
The SONIC is designed to perform exceptionally well in varying wind conditions. Whether you're kiting in light breezes or strong gusts, it maintains its shape, responsiveness and efficiency. The enormous depower minimizes risks and ensures that you can confidently push the limits in a variety of conditions and on any terrain. The kite features a sophisticated bridle system and refined canopy profiles that ensure the kite flies consistently smoothly.
ENHANCED ACCESSIBILITY
The kite has advanced aerodynamics that make it incredibly stable in a variety of wind conditions. This allows you to focus fully on your riding rather than constantly correcting the kite. The internal structure speeds up inflation so that the kite can be controlled as quickly as possible - especially in strong winds when launching. After a crash or a kite landing, it can be launched with minimal effort. In an emergency, the kite will blow out on a single front line after activating the quick release.
