Flysurfer Sonic 5 2025

Updated January 27, 2026 · Tested by Lolo BSD

The Flysurfer Sonic 5 is a high-end kitesurf kite built for pure performance: Big Air, airtime, and kiteloops. You get powerful vertical lift, extended hangtime, and fast, precise loops thanks to its stiffness sleeves. This kite delivers stability that inspires confidence even in marginal conditions. The kites mentioned are in the Kites section of the shop.

Lolo BSD put the Sonic 5 through its paces in real-world conditions. Here's a summary of his field feedback and GlissEvolution's take.

What We Noticed

  • Extended hangtime: Optimized pendulum dynamics keep you in the air longer.
  • Precise and fluid loops: Tighter turning and improved heliloops.
  • Powerful vertical lift: An increased aspect ratio and refined profile deliver explosive take-off.
  • Stability and control, even in turbulent conditions, with effective depower.

A design focused on stiffness and transport

Open the pack and you'll find a surprisingly large bag. The reason is simple: the Sonic 5 incorporates stiffness sleeves that extend halfway across the kite's width. Unlike classic foil kites that fold in half, this construction requires lengthwise folding. This results in neat storage and easy transport. The bag even has a practical strap and a small accessory pocket.

Designed for Big Air and kiteloops

The Sonic 5 has a clear mission: Big Air, airtime, and kiteloops. From your very first runs, the power of the lift will impress you. Each jump is a true catapult to the sky, with a pleasantly surprising sensation of height and duration in the air. You'll quickly realize this kite is designed to push your limits and chase jumping performance.

Fast and precise loops

Loops, both kiteloops and downloops, directly benefit from the kite's design. The large stiffness sleeves create a compact structure. This allows the Sonic 5 to turn with remarkable speed and precision. Whether you're riding aggressively or more smoothly, the kite responds immediately to your input and gives you total control.

Stability and upwind performance

Even in marginal conditions, the Sonic 5 remains surprisingly stable. During lulls, it perfectly holds its position at the zenith. This offers reassuring safety, even in winds as low as six knots. Its exceptional upwind performance is another strong point. Thanks to its high aspect ratio, the kite quickly crosses the window and positions itself far at the edge. This provides truly outstanding upwind performance. This is ideal for transitions and long tacks.

GlissEvolution's Opinion

After a session on the Sonic 5, the verdict is clear: this kite impresses. Its powerful lift, generous airtime, fast loops, stability in light wind, and upwind performance make it a benchmark for Big Air and kiteloop enthusiasts.

Who is it for? Intermediate to advanced riders looking to push their limits and experience thrilling jumping sensations. The lengthwise folding, required by the stiffness sleeves, takes a little getting used to for storage, but it's not a dealbreaker.

Verdict: A refined, high-performance, and reassuring kite that ticks all the boxes for modern Big Air. Our team will help you choose the right size based on your body size and local spots.
