R4D (RAD)

FREEMOVE

The R4D is designed for YOUR type of expression. Use it for freeride foiling, ride it as a freestyle sail, carve moves on your foil, and go as R4Dical as you dare.

Designed with Balz ‘Radiculo’ Müller, this sail adapts to every rider’s ambition. Balz pushes it through signature aerial stunts while the R4D remains accessible for everyday sessions, transcending traditional boundaries. The new FoilWave dimension opens unexplored territory – draw lines in waves regardless of conditions.

Four battens – that’s what the “4” in R4D delivers. This configuration maintains precise balance between maneuverability and stability throughout the entire size range. Smaller sizes enhance quick turns, mid-range delivers versatile performance, and larger sizes provide freeride power without adding weight.

A sturdy, but lightweight construction makes the R4D among the lightest in class. Premium materials and strategic panel layout strip away excess weight without sacrificing durability. Less weight means more response and longer sessions.

Rediscover that true feeling of freedom that started it all. The R4D’s versatility, promoted by an Xtended Range, strips away complexity; maximum range, minimal equipment. Break barriers, R4Dical freedom awaits.

Description
