Kaohi Foil Drive Throttle Wrist Leash-Orange

The Kaohi Foil Drive Throttle Wrist Leash is a purpose-built wrist tether designed to secure a Foil Drive throttle controller to the rider's wrist during electric-assist foiling sessions. Produced through a collaboration between Kaohi — an Encinitas, California–based leash maker known for its Grip Leash and Double Coil lines — and Australian electric foil brand Foil Drive, this accessory addresses a simple but important need: keeping the handheld throttle attached and accessible while riding hands-free. The current version reflects a May 2024 redesign that updated the cord and the controller connection point.

• Cuff material: Neoprene-padded wrist cuff
• Closure: Adjustable hook-and-loop with stainless steel slide
• Cord: Marine-grade nylon lanyard
• Attachment: Stainless steel clip (removable)
• Foil Drive compatibility: Assist, Assist MAX, Assist Plus, Assist Slim, Fusion, V1 Motor, V2 Motor, HP Motor
• SKU (Foil Drive): FD085

This leash is for any rider running a Foil Drive electric-assist system who wants added security for the wireless throttle controller. During downwind runs, dock starts, or transitions where the rider lets go of the throttle, the wrist leash keeps the controller from dropping into the water. The neoprene cuff and one-hand tightening design suit riders who need to adjust fit quickly on the water without removing gloves or stopping.

Because the leash is compatible across Foil Drive's full current product range — from the entry-level Assist to the high-output Assist MAX and Fusion systems — it serves beginners through experienced electric-assist foilers alike. It is not a board leash or a safety leash for the foil itself; it functions solely as a controller retention strap.

Kaohi's broader catalog focuses on foiling and surfing board leashes, including the patented Grip Leash with its integrated rail-saver handle and the Double Coil lines built for prone, SUP, and wing foiling. The Foil Drive Throttle Wrist Leash sits outside that core range as a co-branded accessory sold through Foil Drive's own distribution network and authorized retailers. Foil Drive lists it under accessories and upgrades alongside items like replacement propellers, motor mounts, and battery components.

For riders who already own a Foil Drive system, the included throttle lanyard is a basic cord. The Kaohi collaboration leash upgrades that stock attachment with a more secure, padded cuff and a sturdier cord — a straightforward swap that requires no tools or modification to the controller itself. At roughly the same price point, there are few direct alternatives; most riders either use the stock lanyard or this Kaohi upgrade.
