BOOST - Unleash its power!


Airstyle, Big Air, Race

The Flysurfer BOOST is a highly efficient L.E.I Race Kite, combining explosive lift and huge hangtime. We took progressive technology and blended it with fast turning speed and everyday usability, for sportsmen who love massive airs or racing around courses.

„Go fast, boost high, loop it! Power is nothing without control.“

Double 3D-Shape & Pre-Tension Technology

Double 3D-Shape & Pre-Tension Technology

Thanks to this technology we can produce a highly efficient airfoil, which results in unrivaled hang-time and unmatched upwind performance.

Effortless Kiting

Effortless Kiting

High performance with maximum control. No un-sudden surprises with responsive and intuitive bar-feedback, easy relaunch and high stability even in the strongest gales or gusty inland spots.

Self Launcher

Self Launcher

With the Self Launcher, we are offering you a tool to easily solo-launch the BOOST. Position the kite at the edge of the wind window, connect the sandbag (which comes with the kite) and place this on the ground. Once the kite lines are tensioned the Self Launcher automatically releases safely at just the right moment.

Free Flow Inflation

Free Flow Inflation

We had to make pumping easier, so we developed a new valve – with a larger opening for increased air intake and easy operation. To complete the system we added a R.E.D Pump. This pump is not only smoother and more durable, it also switches from double hub to single hub under high pressure to ensure effortless use.

The Wind Range Chart is to be used as a point of reference. It is based on a rider who weighs around 75kg (165lbs.) Actual use will vary depending on your weight, skill level, board size and the wind conditions on the water or land. When choosing a kite size, always use common sense and always choose a smaller size if you are not sure, especially when using the kite on land.
